[TCML] Re: 3D printed coil forms

   Hey Joshua,

   I have 3D printed many coil forms which was my main reason for buying a
   3d printer.

   Not sure what software you use, but Tinkercad is free online and has
   worked well for simple designs for a complete 3D software beginner like

   I have been using PETG a lot – seems a good all-rounder and works well
   even for nested toroidal coil formers which are quite intricate. Not
   perfect as the smaller wire guides can snap easily (as I found making
   the center of spiral toroidal coils very difficult to complete

   I’m now using PA12-CF Nylon filament for high temperature exposure –
   has a warping temp of nearly 200C, and really strong. Working out great
   so far on this printer (Prusa MK3S+).

   Some toroidal coils are just beautiful to look at when finished, whilst
   trying to figure out what they can actually be used for!

   Has anyone experimented with 3D printing coil forms?

   I’ve used the pvc pipe on the past, but there are a few issues there:

   Limited to particular diameters; 2) While ID is well-regulated, the OD

   vary and be out-of-round; 3) Cutting to size is necessary.

   All of these issues could be solved by 3D printing, limited only to the

   dimensions of the printer. Better for SSTCs than big spark-gap coils.

   main concern is the dielectric strength of common materials in 3D

   like PLA. I can print PLA and PETG on my FDM printer. ABS would require

   some upgrades.

   Also, you could do some really odd stuff, like coils that changed

   over the length!

   Anyone have comments or experience?

   Thanks in advance.
