Material Data For FabEpoxy

Member of Material Category: Thermoset Polymers

Description

FabEpoxy is a special 2 part epoxy formulated for Fab@Home by Kraftmark Company of Spring City, PA, USA. Is has been designed to be thixotropic (meaning that it will flow when you extrude it, but does not flow after extrusion, so layers stack up), and to have a relatively long "pot life" (meaning time between when you mix it and when it starts to harden) of 2-3 hours in typical conditions. This allows you sufficient time to use a syringe full of the material without having it harden in the syringe. At room temperature, the material takes 24 hours or so to become rigid; warm cured FabEpoxy to 80F/27C for a few hours to increase hardness.

Techniques and Notes

Loading syringes can be messy, but with practice, loading into the top of the syringe barrel can be done fairly cleanly, and without trapping too much air. Try to make all of the loaded material adhere to one side of the interior of the barrel. Then, when you insert the piston, you can squeeze it all toward the tip and most of the air can be pushed out in the process. The initial parameters used here leave slight gaps between strands, and I have not yet tried other than the green (840um) taper tips. More experiments will yield improvement in part quality.
