Holy Coaster Batman!

Post by hanselcj » Fri May 30, 2014 11:33 pm

I have gone a little coaster crazy recently. I picked up a few pieces of HDPE from inventables on kind of a whim as part of an order. After seeing someone on reddit making star wars coasters out of acrylic with a laser cutter I had a thought... I CAN DO THAT! It started small with a friend and few coworkers, but after word got out they took off. Now lots of friends and coworkers are getting their school, favorite car manufacturer, or video game put on a snazzy coaster for them.

HDPE is a pretty nice material to work with. I found the following settings worked best with a straight fluted bit. Upcut bits make a huge mess of things.

Time to buy more HPDE. There are a bunch more Dr Who and UCF Pegasuses for me to make.

Look awesome. Can you share your workflow? Did you go with inkscape to makercam? Where did you get your 2d images?

I would find the logo I needed online. Many were pretty easy to work with, some needed manipulation. Open up your desired logo in inkscape and use the "trace bitmap" function to get a set of vectors. I found that the color quantization mode was the most successful. Sometimes trial and error is needed. Add a circle outline, and with the SVG created I move into makercam. Typically it is just a single pocket, then profile operation. At some point I will graduate into a more sophisticated program, but this works well for now. I pull the M30 command out of the last line of gcode because it screws up my zero when the code finishes. Lastly I load the gcode into UGS and then off to the races!

No paint, It is the two tone HDPE from inventables. Not much sticks to HDPE, so I would not advise painting it.

Has anyone found a source for this type of material in the UK/Europe?
I have to admit to not looking myself yet, but if nobody has found any, I will go on a hunt.

I think you may actually be talking about the post I made on reddit! My brother is the one who lasercut/etched those starwars coasters. I had the same exact feeling as you once I got my shapeoko, first thing I did was make coasters. Your use of the dual color looks much better though, I will have to try those out. I also use the same workflow, random image from google ->trace bitmap in inkscape ->makercam. Do you find that the trace bitmap gives you a ton of little circular paths sometimes?

Here's what I've made so far:

Tronn: might have been the guy. They were multicolored laser cut acrylic... very nice! I havent had many issues with the inkscape tool causing lots of circles. I think I have given it mostly easy jobs though. Trace bitmap has 3 tabs to it. Look under the second one and try to play with the "suppress speckle" option. That might help. Also, make use of the color quant when ever possible. That one has been pretty bullet proof for me.

Did you do most of yours with a follow path operation? Those look good. Some game of thrones engraving is going to have to be in my near future. This season has been awesome!!!
