117: PC Case Engraving

To ring in the new year, and celebrate the ten year anniversary of my previous build, I decided to build a new PC. Back in 2007, it was two years before we even started playing with lasers. This time around, I knew for sure I’d be laser engraving some piece or another. I’ve engraved a few macbooks and other portable devices, and I’ve even engraved a custom wood faceplate for a friend’s ATX midtower. So I’ve been pretty excited about the idea of engraving something on my own machine!

Over a few weeks in January I did the research, collected the parts, and then planned a small “build party” with some of my local PC enthusiast friends so we could put the machine together together. Hey, it only happens once a decade or so, that’s a pretty good excuse for a shindig, yeah?

Together we had dinner, built the PC, played some couch games, and mulled over a few remaining questions. What should this new build be called? What part of the case will be laser engraved? What are we going to engrave on it? I was so wishy-washy on the name decision that I couldn’t even settle on it before the party was over. Furthermore, I wanted the engraving design to be related to the name, so I couldn’t really come to any decisions on that front, either. But we were able to figure out what part to engrave, and as it turned out, the answer was nothing.

Fractal Design’s Define C case is sexy, but made out of questionably engravable plastic.

The Fractal Design Define C is a sexy, sexy midtower ATX case. I love the shroud, I love the quiet, and I love the flat textured front. I like simple, unassuming case designs, and I wanted to continue down that road after my last build in an Antec P180B. But when we finally dug into the case, I learned a few laser-unfriendly things I could probably have sussed out from reviews online if I had been more thorough.

The front of the case is not an anodized aluminum plate, and it’s also not easily detached from the surrounding plastic chassis that covers the front exhaust system. It’s made out of the same plastic—it’s very pretty, with a subtle vertical brushed texture, but it’s still just the case plastic. Because the textured surface isn’t repeated anywhere on the inside (or indeed on any other external surface) I wasn’t going to be able to do an inconspicuous engraving test. So I wouldn’t be able to engrave the front plate, but what about the window?

On a quest for extreme sound dampening, my previous PC build didn’t have a window at all. But over the years I’ve kind of missed being able to peek in on my parts, so this time I bought a case with built-in acrylic window.

With a power shroud for modesty and excellent cable arrangement, who wouldn’t want to peek inside?

Unfortunately, there wasn’t going to be an easy way to test that material inconspicuously either, and with the  engraving quality difference between cast and extruded acrylics, I didn’t want to gamble.

When I looked closer at the acrylic window, I noticed there was a lip on the inside, one that would fit a secondary piece of acrylic just fine as long as the measurements were correct. So I did a couple of sizing tests with some old pieces of acrylic, got my measurements spot on, and settled on a solution: cut a separate piece of cast acrylic and snap it into the existing acrylic window. I wouldn’t technically be engraving the PC case after all, but the finished piece would still look as good. As a bonus, I’d be able to easily change out the acrylic in the future if I wanted to change the design.

Amusingly enough, it was mulling around design ideas that led me to my final decision on the name of the machine. I’ve always been a fan of the Metroid series, you can see it in some of my other projects. Most game servers I host have names based on “Maru Mari”, and you’ll be connecting to “Varia” if you try to stream content to my television. I had a feeling I’d end up going with the Metroid theme again, but it wasn’t until I thought about how much fun it would be to engrave the cold steel corridors of Tourian into acrylic that I really landed on it.

The full map is too big; I’d have to fit it in this cyan rectangle

Tourian is a big map. Well, it’s not big, but its hallways are long and the vertical shafts are all a daunting climb. I’d have to compress the map pretty significantly to make it fit the relatively tiny space I had for my acrylic window. To make matters worse, halfway through the design I realized I had laid out the template wrong and was designing for the measurements in landscape instead of portrait. But after cutting a few rooms in half (and completely excising the hallway before Mother Brain’s chamber) I was able to make it fit.

The final compressed map, corrected to a portrait aspect.

I added a few additional details (the opening text scroll and an excessively big title in the original typeface in the corner) and the design was finished. I cleaned up the acrylic, seated it in the window’s lip, and used a tiny bit of clear packing tape on the inside corners to make sure it wouldn’t somehow come loose.

The panel looks great when it’s not connected to the computer, but as it turns out, I should look into buying some motherboard-powered LED strip lighting to brighten up this design. Most of the photography here is cleaned up to make the engraving visible, but it’s much more subtle than that when properly installed on the PC.

This door is all that’s left of a completely deleted room. Don’t tell the purists!

The end result may be disappointingly dim, but I still had a blast manipulating the Tourian map in a way that wouldn’t compromise the basic layout, and I will definitely be using what I’ve learned on this project to make some more “window inserts” for this case in the future. Once it’s lit up, the design itself should really shine, but for now it still makes for some pretty fun close up photography!

The engraving fights with the inner bits just a little more than I’d hoped.
I love that the escape shaft coincidentally has its own murky yellow and green lighting.

116: Laser Foil

Years ago, I purchased a roll of a foil material when I was first getting creative with the laser. I didn’t really know how it worked, and most instructions required a process I was wholly uncomfortable with: touching the material in-between passes. Most of my experiences touching anything between engraving and cutting meant engravings that fell out of alignment, so my poor roll of black laser foil was left mostly unused for several years.

The metallic foil shines bright red from most angles.

This year, for a New Years Party happening in just a few days, we were asked to design name badges for the attendees. For part of the design, Jen and I wanted to use a thin sticker on top the base badge acrylic, but since our normal supply of paper-thin acrylic didn’t come in red, we had to find alternatives. At some point I was reminded of the laser foil, so I ran a quick test with the black roll I’ve had on hand and quickly realized that would be the way to go.

Laser foil in rolls; one black roll from years ago and the red roll bought for this project.

The foil would have to be red, though, because of the design chosen. The badge design for this event features two small dogs sipping their drinks (art by 957thedog.com!) next to a large dumpster fire—complete with a burning “2016” sign inside—the symbolism of which I’ll leave to you to interpret. That fire wouldn’t really stand out if it was just engraved onto the same smooth silver surface the badge is made from, so red foil it would be!

There are a few different ways to use laser foil effectively, but the way I settled on is described below, and it requires a few different steps that have to be done in order.

Black fills are raster engravings, blue and red are vector cuts of varying depths.

Make sure you only run your raster engraving first—the black and grey fills will convert to halftone and result in the surface engraving seen in the photography, while (in this configuration) the blue and red lines are score and cut respectively and will be done next.

Engraving done, now to carefully apply the foil.

With raster engraving done, very carefully apply a portion of laser foil to the surface, overlapping where your blue and red lines will do the dirty work. Since the fire design element is completely enclosed, you don’t have to worry about aligning the foil too much. Just make absolutely certain you do not nudge the material out of alignment during this step. I use an old iron bookbinding bar to keep my material in place.

The foil is applied; it doesn’t need to be perfectly aligned.

Set your software up to cut the blue lines next, and then the red lines after. You don’t need to stop the process in-between unless you want to turn on air assist for the cutting portion. Once all three processing steps are completed, you’ll have a finished badge with a bunch of extra foil on it.

Peeling foil back isn’t as troublesome as peeling vinyl; not nearly as stretchy!

Carefully remove the foil. It’s not as bad as weeding vinyl, thankfully, as the foil doesn’t easily get bent out of shape. Once you’re done, a light cleaning with some denatured or isopropyl alcohol and the badge is done!

From certain angles the reflection looks even more firey.

Because of its reflective nature, the foil fire will catch reflections and create a high contrast black and red look, while the smooth silver below will be bright in low light and aid in badge visibility. I did consider for a brief time going with a classic “dumpster green”, but the back color (white) didn’t work with the design well and, frankly, the results were too ugly to even consider photographing.

Happy new year!

111: Bottlecap Sign

It wasn’t all that long ago that the craft beer explosion happened, but it’s hard to think back to when beer—at least in my life—was a choice between Budweiser and Miller products. While I’m sure there’s debate aplenty about the community that formed around craft beer, you can’t dismiss all of the awesome artwork that community has produced. One of the best design ideas I’ve seen spreading around the Internet has been beer cap holders. They come in many sizes and shapes—usually states and countries—and are an artistic way to keep track of which craft breweries you’ve sampled fizzy drinks from.

The fact that most of these holders were laser cut was only part of the reason for my interest; many of the examples I saw had different amounts of studs to grip the bottle caps, and I wondered which one was the best solution. Sure, I could’ve done the research and stopped there, but that’s not nearly as much fun. A bottle cap holder I would make!

A stack of prototypes, some with six studs and some frightfully too small.

In my research, I learned that most pop caps (and the twist caps based on their design) have 21 teeth. Despite this, my first few prototypes had six studs. Once I realized they didn’t fit very well on the teeth of the caps I redesigned to include seven evenly distributed studs. I also experimented with stud design, settling on trapezoids after rectangles were too tight and triangles were just a little too loose. This mission to match the studs with the cap teeth would eventually cause me an issue: Goose Island’s caps have 27 teeth! Every other cap I had was only 21. While some size variance made some caps tighter and some caps looser, only Goose Island had to sit this one out. I hate geese anyway.

Bottle caps have feelings too. Look at how well the studs fit between the teeth!

Once I had a single cap holder squared away, I spent an unreasonable amount of time trying to fit a grid of them into the word “beer”. I agonized over spacing, wanting to stick to some kind of grid without ending up with awkward, noticeable gaps. It wasn’t long before I realized I’d have to design my own letters based off of the grid rather than relying on otherwise well-made typefaces.

After a few attempts at grid-based letters that turned out far too large for the scope of this project, I ironically ended up back at a typeface: one I designed years ago based off of the bitmap version of Chicago present in Final Fantasy VI. Why not add a geeky touch? It also very easily solved the issue of making the letters fit on a grid due to its low resolution pixel quality.

Once I had the design complete, I whipped up a quick (and honestly lazy) box joint connection to hold two pieces together; the sign was very nearly three feet long and I couldn’t cut it out of one piece of oak ply. In hindsight, I should have engraved the sections of wood that held together each letter; they’re just a little too noticeable and wouldn’t be if darkened. I also inserted some small holes for screws that will eventually hold this a small distance from whatever wall it ends up on. A light sanding later and the finished piece was ready for caps!

Goose Island just had to have 27 teeth. Figures. Geese.

…As it turns out, I don’t have many caps. I’ll fix that!

 

86: 3D Letters

Looks nice and solid for paper, eh?

So, apparently I’ve got weddings in the brain.  For a friend, of course, I got that done over a decade ago myself.  Bridesmaid dress is purchased, invitations are nearly done, we will scouting wedding venues this weekend!  For this week’s project, my mind turned to table decorations.

Making 3D letters has been on my list every since I saw the “8 bit” 3D word project in the book MiniEco by Kate Lilley.  There was not a lot of instruction in the book, and the only letters available were an 8, B, I, and T.  So, off to the internet!  I found three different free printable 3D letter sets (if you want to try this yourself!)

Mr. Printable’s 3D Alphabet

Punched out Font by Shasta – Extra cool because every letter is made of a singe piece of paper!

Alphabet by Digitprop – Seriously cute 3D letters in animal shapes!

Mr. Printable’s were my favorite, so we created a laser friendly version of the letter M, the new family’s last name.  The bride loves bright colors, and I had this fabulous peachy orange mulberry paper with gold designs.  I used spray glue and mounted it to 100 pound card stock, making it nice and sturdy.

The laser makes cutting outlines a piece of cake, but the best part is that the laser can score fold lines too.  It’s a light partial cut that lets you make all folds sharply and in the right place – it’s amazing.  Folding took zero thought!  (We also used this technique for Week 33: Google Cardboard as well.  For tips on paper cutting, check out Week 66: Tips for Laser Cutting Paper)

It was a fun little project, and they were surprisingly sturdy when finished.  I can’t imagine making tons of them, but they would be super cute on a reception table.  Unless, of course, the bride asks.  I’m a sucker for helping and crafts!
