I made a homebuild 5 axis CNC machine and making a mold by my machine see this link : • DIY - homebuild 5axis ... This video shown how i made a first fiberglass mold.
Great job,, Love the 5 axis machine, it's just a thought, but I sometimes use compressed air to help separate items. might just lift your fiberglass right out of the mold.
Olá !!!!! Parabéns pela construção da maquina cnc ..... Acho que para você poder desenformar do molde sem perder o mesmo vc pode tentar usar várias técnicas combinadas .... usando cera no molde antes de aplicar a resina com a fibra e tbm pode injetar ar comprimido depois da peça pronta ..... kisses from Brasil! !!!!
My friend. Next time dont destroy the mold. Do a small hole at the bottom and use compressed air. Then correct the hole and your are OK for another part. I really like your machine. I want to modify a plasma cnc machine I have to build a bigger frame in order to do 10m x 2m x 2m molds for laminates. I really like the Z axis you did with the 4th axis.
I am using a glue which is call - "Water-based adhesive for bonding of insulation materials" and may be you can find some at insulation meterials shop at your area.
