Hi All,

I’m planning to print a plate & case for a handwired 46-key split kb. I have access to both SLA & FDM printers at a fab lab, so wondering which printer tech would be best to print various parts such as keycaps, plate, case etc. Function’s more important than looks for me.

I’m allowed to use PLA or TPU for the FDM, and the default resin (ABS-like?) for SLA.

I’m thinking:

  • Keycaps: SLA (I want really thin keycaps)
  • Plate: ?? (not sure what’s better for a thin & durable plate that allows a bit of flex when typing)
  • Case: FDM (Due to costs, and easy to embed screws & magnets)
  • Wrist rest (if any): FDM? Would TPU wrist rest be clean or comfortable?
  • Gaskets, extra layers (if any): FDM (cuz TPU)

What do you think?

    Your current plan is solid. Print the plate with fdm, though it can’t be too thin. There are a few designs on thingiverse and etc. to get an idea on how thick.

      Hmm what’s the rationale to print the plate with FDM? Are SLA plates brittle or inflexible? (if printed with ABS)? I don’t have much experience with SLA. And good point, I’ll check Thingiverse for the thickness.

          Ah that’s true. I got the SLA printer’s build volume and indeed it can’t fit a whole half of the split kb in any way.

          I think this SLA printer can print ABS. Or at least I’m told the default resin is ABS-like. Probably not as durable I’m guessing.
