I'm a maker and I've been interested in 3d printing for years.
I have found a technique for dissolve the PLA supports in a model printed in 3D in HIPS
- I have printed the model in HIPS and the support in PLA
- I have put the 3D model in a ultrasonic cleaner in the solution with water and sodium hydroxide
(1 liter H2O + 200 grams NaOH)
The PLA has dissolved after 3 hours with temperature 65° and 1 hour of ultrasonic sound.
I attach a youtube link with a similar experiment
Is it possibile use another substance / solution less dangerous and less toxic?
In theory, the PLA is biodegradable. Is it correct?
Ps: I want use this combination of materials HIPS for model and PLA for Support.
Thank you in advance for the answers.
