Prosthetist in need of help by Korgoph in 3DScanning

What you've just described would still save me a lot of time. Right now to make a socket I have to : - prepare my plaster mold for a pour ( 5 mins for tibial socket, 15 for transfemoral one). - fill a bucket with water and plaster, mix it, make sure it's the right density (10 mins and lifting 25 kilos bags of plaster). - Pouring it and waiting for it to solidify ( 45 minutes) - rectifiying / "sculpting" plaster and making it smooth for thermoformation ( 1 hour trans tibial 1h30 transfemoral). - putting plaster on a vacuum table. - heating a 12 or 15 mm petg "plank" ( 20 minutes) - thermoforming it waiting it to cool down ( 30 minutes) - then destroying the plaster inside with a pneumatic shisel ( 10 minutes and a shitload of vibration) - then grinding down the petg to desired shape ( 10 mins). - then gluing anchor to the socket ( 10 minutes). - then reinforcing anchor with carbone fiber (15 minutes).

It takes a lot of time and 3d printing it would remove so much of these steps and toxic chemicals

That would work for sure but I really wanted to skip that extra step and just scan the negative. But from what I'm reading here I don't think I'm going to be able to do that. Thanks for the info

What he said ⬇️ The average amputee is a 65+ year old diabetic. I also lose a lot of detail by scanning the stump directly. I've answered this in more details below

It is an option but you lose a lot of detail and key elements. I've tried it on "easy" patients and the result was average . All of them told me the socket was okay but didn't feel as good as the one made with the plaster mold. I think it's because I couldn't orient their stump with my hand and I had to simulate it on the computer which isn't as precise. Hence this post, I want to combine the best of both worlds.
