Fiber Laser to Color Change Plastic: Hard Drive Marking

In this blog post, CNCROi.com color changes plastic… without melting it… on a hard drive using our fiber laser tube. The results are permanent, the results awesome!

 

Having a dual-sourced industrial wide format Austrian CNC laser has many advantages but one that isn’t shown too often is the ability of our fiber laser tube (we have a CO2 as well) to color change plastic without melting it.

If we tried what you saw in the video and images below using our CO2 laser source, it would be a hot mess, here’s a picture showcasing the difference but it would be worse because this is a rubbery kind of plastic, not solid like the earlier hard drive test we did.

As we aren’t actually touching the hard drive or components with anything but surface light, the electronics inside are safe, they are not heated nor are there any vibrations of any kind. This has no effect on the hard drive at all.

Why would somebody want to do this? There are several reasons, the first is branding, it’s permanent and not coming off. It’s also a fantastic way to kill the resale value or possibility of theft as the mark is permanent. If needed, we can also engrave the internal hard drive inside as well so just removing the casing still wouldn’t be a way around theft or resale.

What is really cool about our CNC laser though is that we can run it through a database, so if you had a thousand of these hard drives needing PERMANENT fiber marking and tracking, we can fiber mark a unique QR code or anything else you want to each one.

This presents a lot of opportunities for our clients, see past the hard drive and think workshop tooling, small equipment and other items that are either prone to theft or you wish to hand out for marketing purposes. We can literally brand any and all surfaces to your specs.

Are there any downsides to permanently fiber marking equipment? Yes, it’s permanent. So, be sure that anything you want us to CNC laser fiber mark or color change won’t be changing anytime soon.

Yes, there are many alternatives to CNC laser color changing, stickers are great but easily come off, scratching these by hand is an option if you have more patience than we do and so is UV printing but those all fade, chip or come off over time. Our process is PERMANENT.

Laser Cut Peach Pie for Thanksgiving

We loved this article so much we wanted to revisit it for this year. Below is a step by step guide as to how to create a lasercut Peach Pie (just imagine it’s pumpkin for Thanksgiving). The Engravers Register wishes all of our United States friends a happy and safe Thanksgiving. Feel free to share your Laser Cut Thanksgiving Pies with us!
The holiday season really starts with Thanksgiving on Thursday 27 November, so why not play around with some cool holiday designs on your pie with your laser machine? The below yummy recipe is reproduced from Instructables, by author Ejosully. Make sure you share any creations with us!
YUMMMM!!!!
Picture of Laser Cut Peach Pie

Step 1: What you’ll need

Picture of What you'll need
Ingredients for the pastry:– 445g plain flour
– Salt
– 175g cold butter
– 95g vegetable fat
– Iced water (or regular water and dry ice, but this is probably overkill)
– 1 eggIngredients for the filling:– 1.2kg peaches
– 100g sugar
– 3 tablespoons cornflour
– Quarter teaspoon ground nutmeg
– Half teaspoon cinnamon
– Juice of 1 lemon
– 30g butterEquipment:

– 9inch / 23cm pie tin
– Laser cutter (optional, but without this it will just be a regular pie!)
– Wooden chopping board
– Large bowl
– Sieve
– Potato peeler
– Rolling pin
– Pastry brush
– Clingfilm
– Greaseproof paper

 Step 2: Prepare the pastry to make the leaves
Picture of Prepare the pastry to make the leaves
Sift 285g of the plain flour and three-quarters of a teaspoon of salt into a large bowl.Add 115g of the butter and 60g of the vegetable fat. Rub the mixture together with your hands until it looks like coarse breadcrumbs.Add 6 tablespoons of iced water and knead the dough together. Gather it into balls, wrap it in clingfilm and store it in the fridge.
Step 3: Cut the leaves in the Laser

Picture of Cut the leaves in the lazzor
Set up the laser:Import the attached PDF into your laser-cutting software. You will probably need to test quite a few different settings until you get it right.Cut the leaves:Break off a bit of the dough and put it on a sheet of greaseproof paper. Roll it out to about 3mm thick.Place the dough and greaseproof paper on the wooden chopping board and pop it in the laser cutter. Depending on how thick your chopping board is you might need to take the honeycomb mesh out of the laser cutter bed to fit it in. When cutting, the greaseproof paper will avoid the dough sticking to the board, and the board will make sure you don’t damage the bed of the laser cutter if you overshoot.

You can copy and paste the leaf vector in your laser-cutting software and set a few running at a time to speed it up a bit. You’ll need to end up with around 50 leaves, so you can probably do ten at a time if you roll out enough dough.

IMPORTANT NOTE!: As soon as you’re done lasering one piece of pastry, put it back in the fridge in a container so it doesn’t dry out. The lasering process will take at least an hour, and the first time I tried this out the crust burnt after ten minutes in the oven because it had dried out while it was sat on the side.

Step 4: Heat up the oven and prepare the filling

Heat the oven to 220 C / 425 F / Gas mark 7.Fill a large heat-proof bowl or saucepan with boiling water. Drop the peaches into the boiling water for at least 20 seconds, then transfer them into another bowl filled with cold water. Leave them to cool down, them peel and slice them.Put the peach slices into a large bowl and add the sugar, cornflour, nutmeg, cinnamon and lemon juice. Put the bowl to one side.Step 5: Make the pastry base

Picture of Make the pastry base
Sift the rest of the plain flour and half a teaspoon of salt into a bowl. Knead in the rest of the butter and vegetable fat, add 3 tablespoons of iced water and mould it into a ball.Roll out the dough about 3mm thick. Transfer it into the pie tin and trim off the edges. Keep the trimmings for decorating the crust later.Beat the egg with 1 tablespoon of iced water and brush the pastry base with the glaze.NOTE: This photo is from the first time I tried this recipe, when I tried lining the pie tin with greaseproof paper to make the pie easier to remove. The paper ended up burning as the pie takes so long to bake, but you might want to use tinfoil instead if you want to transfer the pie onto a plate for serving.Step 6: Add the filling and arrange the leaves

Picture of Add the filling and arrange the leaves
Pour the filling into the pie, piling it a bit higher in the middle. Dot with the 30g of butter.Arrange the leaves on top of the filling, starting at the outside and working your way in. Finish it off by rolling some of the pastry trimmings into balls and using them to cover the hole in the centre.Brush with the glaze.
Step 7: Bake itBake the pie for 10 minutes, then lower the heat to 180 C / 350 F / Gas mark 4 and bake it for another 35-40 minutes.Check on it regularly as the crust is prone to burning (see pic 2 for my first attempt at this, which went slightly wrong).Enjoy, it tastes lush!

Following up on crowdfunding

We can’t believe it’s a year ago that we looked into the concept of crowdfunding as a method of financing your laser machines and equipment. Given the launch of the exciting new concept Lasers for Education, a crowdfunding program and site specifically developed for the educational sector, we thought we might revisit this option and how to manage it. Below is our original blog post from 23 November 2014.

“Crowdfunding” is the latest catchphrase in the finance and funding world, but how relevant is it to the engraving industry and is it worthwhile option to investigate separate to the normal finance and leasing options? There are so many platforms out there, which is the best one to use? Australian business, Chocolate Brownie Leather (CBL) recently used the Kickstarter platform to successfully raise funds to purchase a laser machine, but is it right for you? Below are some considerations.

Firstly, it’s important to identify WHY you are looking to raise funds. Are you looking to raise money to start a business, upgrade your laser machine or looking to commence a dream engraving project that you couldn’t fund as part of your normal business operations? You must have an end goal in mind as many crowd-funding sites have limitations on projects and different types of sites are suited to different purposes. CBL need  to raise some additional funds to secure finance for the purchase of her Trotec Laser machine. CBL had a set goal in mind and usage.

Secondly, what is the best platform for you to use? Kickstarter is focussed on creative industries, there are equity funding sites for start-ups (if you’re looking to establish a business) and even crowdfunding sites dedicated to helping raise funds for lawsuits! Google even has it’s own crowdfunding tool, Contributor for publishers. Thoroughly search the various sites and options before deciding on your preferred site. How long will you want to raise funds for as well?

Thirdly, ensure your project has suitable rewards for backers and is seen to minimise their risk. CBL offered a range of beautiful quality hand-crafted leather pieces as rewards for her backers (there was a range of rewards on offer for backers). Plus using Kickstarter, backers are not charged until full funding is achieved.

Finally, you still have to work  for it! Backers won’t just come to you. Just like any other element if your business, you have to market and sell the crowdfunding component to ensure success.

Crowdfunding can be an out-of-the box way of raising funds from backers around the world, so it’s definitely worthwhile investigating whether it suits your business model.

Below is Chocolate Brownie Leather’s Kickstarter promotional video.

Our favourite guest Engravers Register blogger Jon from CNCKing.com is also part of the Kickstarter action. He has 8 days to go in his campaign – good luck!

CNC Laser Cutting Old 1/4 inch (6 mm) School Shelving into Kid Activity

We think this is a great idea, and particularly relevant for our new partner Lasers for Education.

Thanks again to  CNCROi.com for your blog post, where we recycle old and worn school shelving into a fun new activity for school children.

I’m pretty sure that these shelves, located in a classroom, are older than me which makes them a perfect material to be recycled into a school activity for children in their school. It teaches them about recycling – instead of throwing out perfectly good plywood – and also give the laser something fun to do!

cnc laser pumpkin shelving

Generally we don’t feature any customer projects on CNCROi.com but I made an exception in this case as it’s just such a wonderful case study of the power a CNC laser can bring into the classroom and the lessons that can be taught that one person’s junk is another person’s pride and joy (after the kids paint them).

cnc laser pumpkin shelving

These are not meant to be stencils but this wood was probably the best plywood I’ve cut with our industrial wide-format Austrian laser. The wood was dry, straight and incredibly well textured from all the decades of kids throwing stuff on and off them. This wasn’t junk by any stretch!

cnc laser pumpkin shelving

The entire project entailed custom cutting more than two dozen “stencils”, with the letter being shown representing the child’s first letter in their last name. The cutting process was incredibly clean, I guess in the old days they had more wood in plywood than glue!

cnc laser pumpkin shelving

The great feature about this project was whether the files were all the same or different, it made no difference at all to us here at CNCROi.com. The laser cuts “on-demand” and although several of these letters were repeated (not shown), the result was always the same. A crisp stencil and outline.

cnc laser pumpkin shelving

It just goes to show you the versatility we can offer a business with their products, instead of throwing them out… send it to customers and potentials for promotional and marketing uses! We can mark, etch, engrave and cut just about any material.

cnc laser pumpkin shelving

While cutting through these shelves, we also discovered some embeded nails, good thing this wasn’t cut using our CNC router otherwise we would have gone through some bits! What fascinated me about that was the laser would essentially cut “around” the nail, meaning that even under the nail, the plywood was cut (as well as above) but the nail itself wasn’t cut (we don’t have that kind of laser).

cnc laser pumpkin shelving

Some of these boards were in better condition than others, but there was surprisingly little warping, again, this was the kind of solid plywood you just can’t find anymore!

cnc laser pumpkin shelving

The entire cutting process was done relatively quickly considering how many we had to do, I could have done quite a few boards at once but I wanted to do one at a time for photographic and video reasons. Our bed is HUGE and we take full advantage of it when we can… which is why client projects are fun… because things are optimized to the hilt as nobody will ever see the light of day that we did it or how we did it.

cnc laser pumpkin shelving

The applications of projects we could have done with this material are endless, it would have been fantastic for model making due to the quality of the plywood, great for signage and stencils due to its straightness, amazing for jigs and just about any other use in the shop or for our clients. We also could have made great custom business cards out of these too.

cnc laser pumpkin shelving

There was very little waste left after we CNC laser cut these pumpkins out of the plywood.

cnc laser pumpkin shelving

Throughout the cutting process, very little vapor was seen, due to the dryness and quality of the plywood. This meant that the video showcasing the cutting of these boards is incredibly clear. This is also due to our extraction capabilities and gas kit, basically pushing what little smoke there was being produced quickly out of our Trotec Speedy 400 flexx laser.

cnc laser pumpkin shelving

I hope you enjoyed the vision that the teacher who rescued this fantastic plywood for their class had… I wish more people were as imaginative to see alternative uses for perfectly good material!

Remembrance Day Poppies 11.11

With Remembrance Day being observed in many countries next Wednesday 11 November at 11am, we wanted to share some beautiful images of poppies created on a laser machine that current students gave to ex-service personnel who were past students, in April 2015 (ANZAC Day in Australia and New Zealand). You can also download the file in Corel Draw (corel v3 and v7) so you can create your own poppies this November.  [download id=”15″]

A wonderful touch and very well received. Lest we forget.

How to make an Acrylic Taco Holder

We loved this idea so much we thought we should share it with you all. This is courtesy of Instructables.com, Acylic Taco Holder created by Joe Gadget and reproduced from the site. The machine used was a Trotec Laser Speedy 300.

Step 1: Materials and Equipment

Vector drawing software (I used CorelDraw)
Laser cutter (my TechShop has a Trotec Speedy 300)
Acrylic strip heater
Acrylic sheet folding tool
1/8″ acrylic sheet

Step 2: Measure a Taco

Taco Holder 1

Seriously.  You have to know how big the shell is before you can make a holder for one.  The brand we regularly buy is about 5″ in diameter as shown in the picture.  To plan the holder I added a couple of rectangles to mark points of interest.  Then, using the 3-Point Curve tool I drew in the base.  Then using the 2-Point Line tool I added the two vertical supports.  In the first few attempts I didn’t like the shapes so simply deleted the red lines, resized the rectangles, then redrew the holder profile.  The reason for using the rectangles is it let me easily make a symmetric design.

Step 3: Make a Top Down Guide

Acrylic Taco 2

Again to make it easier to create a symmetric design I dropped down a series of rectangles.  I sized the three large rectangles from the profile in the previous step.  CorelDraw reports the lengths of line segments (including arcs), and I used that to get the 2″ and 3.25″ horizontal dimensions.  Two tacos standing up against each other are about 2″ wide at the top, so I decided to make the widest points of the holder 3″ wide.  I then added the smaller rectangles to help define the openings in each vertical piece and the narrowing of the base in the middle.

Step 4: Draw the Top Down Profile

Acrylic Taco 3

Using a combination of the 3-Point Curve and 2-Point Line tools I drew the top down profile of the holder.  Make sure you use the hairline setting for the profile so that these lines will be cut and not engraved.  Once you like the shape, delete all of the guide rectangles.  I added two black lines (to be engraved) to show the fold lines on the holder (in hindsight it was pretty obvious where the folds would be and I could have skipped this step).

Step 5: Laser Cut the Acrylic

Acrylic Taco 4

Acrylic cuts and engraves quickly and easily.  For engraving I used 100% power and 80% speed, and for cutting I used 100% power and 0.7% speed.

Step 6: Fold the Ends Up

Acrylic Taco 5

Acrylic Taco 6

An acrylic strip heater generates a line of hot air that will locally heat and soften the acrylic for bending.  The acrylic sheet folding tool can be positioned and locked into place so that the acrylic can be bent to a specific angle.  For this holder I set the angle to 105 degrees (so that the ends will be folded slightly back onto themselves).  Line up the first end of the holder over the hot air opening, and after a few minutes the acrylic will be soft enough to bend. Bend the end up partially by hand then press the holder into the folding tool.  Hold it in place for a few minutes to allow the acrylic to cool and set in position.  Repeat the same heat and fold process on the other end.

Step 7: Bow the Middle of the Holder

Acrylic Taco 7

I wanted to curve the base of the holder, and the strip heater doesn’t heat a large enough area.  So I placed the holder over the hot air opening, and shifted its position every minute.  This slowly heated the entire middle of the holder, which I was then able to bend by hand into a gentle curve.  This completes the taco holder!

Step 8: Make Tacos and Enjoy!

CNC Laser Engraving & Cutting Custom Wedding Cake Toppers

Another great “how to” by our supporter CNCRoi.com.

For the past year, CNCROi.com has been solely focused on manufacturing, mill work and aerospace industries, the reason is simple, they have the volume and expertise that utilizes our capabilities to the fullest. Now that we are in our second year of operation, we are expanding into new markets that can benefit from our industrial expertise in areas that aren’t being well served.

Our first stop on the diversification train is custom cake event toppers, specifically, wedding and birthday. We are, of course, still going full throttle with our “traditional” markets and expanding them further thanks to our unique dual-sourced Austrian wide format CNC laser, we are just opening our doors wider now into new areas. The more volume we can get into the shop, regardless of source, the faster we can acquire the equipment we are saving-up for to maintain and expand our lead in the custom CNC marketplace.

custom wedding cake toppers

These custom wedding cake toppers were custom designed by CNCROi.com in-house. This makes us a very unique entrance into the wedding cake topper market as our stuff isn’t imported. It’s CUSTOM DESIGNED, CUSTOM ENGRAVED AND CUSTOM CUT on any material you wish FOR YOU.

custom wedding cake toppers

The entire process can be as fast or slow as you wish, generally, give us a day to design and cut though this can vary to 2-3 days depending on the number of revisions, material selection and other stuff we have going on in the shop.

custom wedding cake toppers

The advantage though with CNCROi.com is that, like our industrial clients, we can easily ramp up production and make hundreds if not thousands of these in very short order. Not only that, but we can customize each wedding topper with the name of the person attending your wedding… as a keepsake.

custom wedding cake toppers

This is entirely impossible and impractible any other way. Why? Because we are a custom mass production business, meaning that in-house, if you need a thousand unique items or a thousand same items, our CNC laser (and operator) don’t care. It’s no problem as we cut, engrave, etch ON DEMAND.

custom wedding cake toppers

This incredible power is now available to you, for your special event… for the FIRST TIME EVER! Having industrial scale expertise and customers has many advantages, that you can now benefit directly from.

custom wedding cake toppers

The nice things about weddings and birthdays is that, generally, you know what the date of the event will be. That gives everybody tons of lead time, and again, you benefit as do we as between production runs at our custom CNC shop, we can fit in custom laser engraved and cut cake toppers.

custom wedding cake toppers

Another advantage that CNCROi.com offers, in addition to custom design and engraving/cutting capabilities and database driven customization of wedding cake toppers is that we are able to make these cake toppers out of any material you wish.

custom wedding cake toppers

In these examples, we make the wedding cake topper out of 6 mm (1/4 inch) birch plywood but that can just as easily have been solid wood, acrylic, plastic, polycarbonate… even stainless steel! What will dictate material options is the design and budget.

custom wedding cake toppers

Taking things one step even further, you can now have a mix and match, which means we can make a custom wedding cake topper for you out of one colored (or multi-colored) acrylic for the cake and make all the others out of plywood or anything else.

custom wedding cake toppers

These options, and a bunch more are all up to you. You want your cake topper to double as a knife to cut your cake? Yep, get one made out of stainless steel. Never seen that before… this is the power that CNCROi.com brings to your event.

custom wedding cake toppers

Not only that… I know, we can expand this infinitely, but we can just as easily make these wedding cake toppers for corporate use, so making them out of your logo as keepsakes or handouts to celebrate a big event. Got your first million dollar contract? Get a custom cake made (we can’t do that) and then get us to make a custom cake topper for it!

custom wedding cake toppers

The quality of our work is evident from both the front and the back. We are truly passionate about what we do here at CNCROi.com and make sure what ever we do for you, you not only are aware of how it’s being made but also get action shots during production.

custom wedding cake toppers

So, if you want to create extra buzz about your upcoming event, we can make videos, photography etc. that you can share on social media so that your awesome cake toppers becomes a conversation piece in addition to a keepsake.

custom wedding cake toppers

Alright, I can write about how awesome this stuff is all day, let’s go back to looking at how these two wedding cake toppers were made, production wise. Keep in mind that the steps change depending on the production quantity, materials and timelines involved.

custom wedding cake toppers

The first step involved with making these custom wedding cake toppers, after the design is signed-off upon, is to mask the plywood (acrylic etc. don’t need this step). The reason why we do this, ON BOTH SIDES, is due to the resins and glues in the wood, we have to do this whether it’s hardwood, softwood or engineered by the way. Once it’s vaporized, the residue which is very sticky, tries to find a place to latch onto, which is generally the surface of the material.

custom wedding cake toppers

The easiest place to latch onto is the front and back of the wood, for engraving, it’s just the front. Once this sticky residue latches on though, it’s very difficult to remove as it gunks up sand paper and most other materials. This is why we mask both the front and back, so that after production, we remove the masking paper which, removes the gunk as the same time.

custom wedding cake toppers

This is why the birch plywood you see in these photos looks “white” (or green actually through our industrial laser window). That’s paper covering things up.

custom wedding cake toppers

After the engraving is complete, we then cut the inside parts and outline. Why? Well, if we cut out the outline first, it will “shift” slightly and so, cutting out the inside parts and the engraving will no longer be the same. We imported an industrial CNC laser from Austria… the precision is insane… and that’s why our customers love us. Just because we are now offering “simple things” like this wedding cake toppers, doesn’t mean we cut corners to speed production up.

custom wedding cake toppers

This is what makes CNCROi.com different. If something takes a bit longer to do RIGHT, so be it, at least you get what you paid for!

custom wedding cake toppers

As you can see from these photos, the masking has burned edges (resin) residue. This is why most laser cut cake toppers look HORRIBLE, because the company can’t be bothered to do things RIGHT. They have a junky machine that’s anything but precise that is simply set-up on the wrong foundation to run a proper custom CNC shop upon.

custom wedding cake toppers

Taking the masking off, you can clearly see the quality of our output. Yes, we masked this (we didn’t have to), yes, we made extra cut lines around the letters (we didn’t have to) and absolutely yes, we custom designed this to spec. We do this because we care about what leaves the shop, we are in business for the long term and CNCROi.com will not last as a business if we only do awesome industrial work but awful cake toppers. Either you do things right and perfect or go out of business.

custom wedding cake toppers

This is plywood, so the results from the laser have a bit of variance. You can see the “white blotch” inside the “Mr.”, upon closer inspection, the wood itself is a different color – in this case, we’d send a photo to the customer for approval before shipping. If you didn’t want that white blotch, no problem we cut another one until you get what you paid for. Easy as that!

custom wedding cake toppers

Here you can more clearly see the quality of the output, our letters are perfectly centered with their related contours, the lines are smooth, not jagged. The engraving is the same depth all over and considering this is wood, a pretty darn good sample of what we are capable of doing!

CNC Laser Engraving Wood Logs (Pioneer Bling)

Our Canadian registered businesses CNCROi.com and Guest Blogger Jon Cantin shows how to engrave wooden logs using his Trotec Speedy 400 flexx laser!

CNCROi.com works with a wide variety of woods during the course of normal operation, including wood logs, or what we like to call, “pioneer bling”.

I grabbed one of the scrap logs from a recent project we did, having a split means it wasn’t to spec but for our purposes here on CNCROi.com, it’s more than fine as a demonstration of what we can do with our Austrian industrial wide-format laser.

cnc laser engraving pioneer bling

After focusing our lens, we powered-up our CO2 laser source (we have a dual-sourced machine with fiber as well) and began engraving away, but first, we had to mask the wood log. The process is the same when we do large natural wood signage, masking, laser engraving and then sealing.

cnc laser engraving pioneer bling

Masking is important as it protects the surface NOT being engraved from vapor and smoke deposits that tend to stick to the surface. The surface may be uneven like this log piece by up to a centimeter without any issues with our laser, as we have a wide focal tolerance when it comes to wood and other materials with similar densities.

cnc laser engraving pioneer bling

In this case, we set-up our CNC laser to vaporise about one millimeter of material from the surface after it was sealed… sealing keeps that “wet look” even when it’s dry and protects the wood long-term from moisture. Sealing prevents the expansion and contraction seen throughout the season as it provides a barrier from local humidity.

cnc laser engraving pioneer bling

The CNC laser engraving went perfect, we were looking to achieve a dark mark that would be clearly visible. Keep in mind, there is NO PAINT FILLING in this project, we are just exposing the charcoal that the laser made during the engraving process.

cnc laser engraving pioneer bling

Taking a look through the masking paper, you can clearly see that we not only produced a very clear set of letters, something not possible with hot branding or CNC table routing, but also exposed the beautiful grain at the same time.

cnc laser engraving pioneer bling

After the masking was removed, there was some smoke overspread exposed, not an issue in this case as it’s easily removed and dramatically less than if we didn’t use the masking.

cnc laser engraving pioneer bling

Another spray of sealant over the entire piece of log once again to keep the charcoal and any wood “seams” exposed during the CNC laser process sealed and the results don’t look good, they look SPECTACULAR!

cnc laser engraving pioneer bling

To give you an idea of scale, I have an averaged sized hand. We can do wooden logs over a meter wide to small little miniature ones to suit any project, several inches to several millimeters in height.
