Making a 3D Printed mold for Carbon Fiber Infusion Process

Firstly I am not a professional. I am a hobbyist that has been playing around with carbonfiber. For the last 1.5 years I have been trying to find a workflow for my 3d printed mold process that can promise great results. I have tried various things and this is so far my best approach with best consistent results. This lenghty video tutorial shares my process from A-Z. No secrets, nothing special, just steps I take to get to the finish line to allow myself to have a mold that has a decent surface but is air tight and works perfect for vacuum infusion process. 0:00-4:20 - Intro & Sanding First Layer 0:21-4:33 - Washing The Mold 4:34-10:40 - Coating First Layer of Resin 10:41-12:11 - Sanding First Layer of Resin 12:12-14:46 - Coating Second Layer of Resin 14:47-16:43 - Sanding Second Layer of Resin 16:44-18:15 - Sanding First Coat of Primer 18:16-19:07 - Sanding Second Coat of Primer 19:08-20:29 - Comments and Concerns on the mold 20:30-21:12 - Polishg Part and Final Comments
