PLA lost method for plastic moulding

Hi Everyone,
I would like to share my experience in the manufacture of molds using the PLA lost technique. In my country, and I think it is the reality of many, the machining of parts is expensive so I decided to approach this technique taking advantage of the ease of 3D printing. I share some results and would like to ask if you have experienced this way before.Greetings to all.

In the images you can see parts made from cast aluminum that were previously parts printed in 3d printers.


Interesting, Could you provide the steps. Are you using plaster and a bakeout oven?

Yes, plaster bake it with incremental temperatures. I will upload pictures and more info when i can continue the work because a new printer has not arrived yet.
