Just about to start sanding and glassing my 3D printed PLA duct. Any advice on the technique, number of coats etc,
Hello perso I sanded with 120 and 600 with water before putting a plastic primer ( 2 thin coats). Then three coats of MOTIP black paint (spray paint) and to finish 2 coats of SPRAY MAX 2K matt varnish.
Thanks @Manu do you think your method is as strong as using epoxy resin?
This is the method I used for my Electric mountain board and it is shock and scratch resistant…
Cool thanks, I might give it a try it sounds a lot easier and less messy than using epoxy
Thanks for the pics, what brand of plastic primer spray did you use?
MOTIP PRIMER PLASTIC
I bought it at FEU VERT car store
Thanks for all the suggestions.
Finally getting round to this! As I still have a little epoxy left I might just paint the duct with epoxy
How does it react to PLA and how do you stop it reacting in the pot while you are painting it on?
