Back in May I ordered a Lulzbot Taz6 about a week or so after it came out — I had been waiting and saving for one for quite a while. I got to try one at the Red Hat Tower, the corporate HQ down in Raleigh NC and was quickly hooked. (I work for Red Hat, but at their engineering HQ which is is Westford MA.) Like many makers with a new 3D printer I spent a LOT of time printing random fun things from Thingiverse and similar sites.
After getting a bunch of prints under my belt the next part of my 3D printing journey was to start designing some of my own stuff to print. My first custom design was this retro looking sign of my last name — Rainford.
I designed the model using SketchUp and extruded my name in the ‘Lobster 2’ font. I then added a base to tie all the letters together into a one piece print. I also extruded ever other letter a bit more than its neighbor so that I could preserve the serifs in 3D and create additional shadow lines.
After creating the model I used a SketchUp plugin to export the model into a *.stl file. I then loaded up Cura: Lulzbot edition to slice and print the sign.
Printer and Settings:
Lulzbot Taz 6
Dark Blue nGen Filament
No supports or brim
Z-hop set to 0.75 instead of the default profile of 0.1 (I wanted the flat spaces to be smooth — worked out this value as I’d tweak it more each time I printed one. I would up printing 4 of these, one for home, one for the workshop, one for the maker bench and one for my office at work. Apparently I can’t get enough of my name or want to get my money’s worth out of the design time it took to create this model. 😉
The lesson I learned from this was in creating some material to connect the dot over the ‘i’ to the rest of the word. The model looked great in SketchUp but that bridge didn’t show up in the print — didn’t like how some of that solid resolved internal faces I could not see in the solid view I was looking at. I eventually learned about the Cleanup^3 and Solid Inspector^2 plugins for SketchUp that helped fix that issue and I’d also inspect via View->X-Ray. So the second print had a properly connected dot. I also now look at the layers view in Cura to make sure the paths, and the brim and supports when needed show up the way I would expect.
