Modular Fiddle in the Sun

Have you tried PETG or ABS/ASA?

[@openfabpdx]

No, but others have used PETG. Generally speaking for the body of the instrument, we want to maximize the ratio of stiffness to weight. I talked in more detail about material choice in this blog post I wrote for Proto-Pasta. www.proto-pasta.com/blogs/applications/anneal-htpla-cf-for-a-truly-durable-fiddle

Have you ever tried printing one of your violins out of ASA or ABS?

[@openfabpdx]

A little late, but.... no, I haven't, but others have. Generally speaking, PLA is just so stiff, so it's a great option. ASA or ABS could work well for the non-acoustic parts, though. I'm just not set up to print them safely.

What temperature and how long did you annealed it?

[@openfabpdx]

David Conley - after much trial and error, I had the best results setting my kitchen oven to 300F and then turning off the oven before putting my part in. Then I let the part sit for 20-30 minutes, in the hot oven, then remove and cool down at room temperature. For the body I use a butter knife to do a bit of reshaping as the part cools.

Whats your annealing temperature?

[@openfabpdx]

I usually anneal at 225-250F in my oven. You can read about my process in more detail here: openfabpdx.com/2021/12/02/how-to-make-a-truly-durable-violin
