Why create a bathroom sign in your own home? Why not! This project was super fun because I got to play with heat guns, resin, and multi-colored prints!
The Tools
- 3d printer
- heat gun
- disposable gloves
The Materials
- green and white PLA filament
- 2 part epoxy resin
The Build
The most interesting thing about this build was the resin coating. There are a few things to learn here. First, resin is nasty, smelly, and sticky so wear gloves. Also, 2 part resin mixed together ends up with tons of bubbles. You remove them by pouring the resin from really high up, but also using a heat gun or torch to pop the bubbles. This only works if the layer is thin — if you are pouring a thick layer of resin, then you need a degassing chamber to vacuum all the bubbles out.
The second interesting thing about this is the dual color extrusion. I do not have a dual color print so I had to modify the G-Code to “pause” the print at the right height so I could swap out the green filament for white. This is done with Cura3D.
