I am getting (delivered tomorrow) 3 FDM printed ASA plastic prototype aerofoils, maximum dimension 600 mm. I hope to use these 1. for quite a few months of functional testing, 2. for making a mould from which to produce lightweight carbon-fibre replicates of the prototypes. Perhaps you can advise me what surface treatment would suit these aims. I want a high-gloss finish that 1. Will not compromise the ASA plastic parts. A compatible system that will not weaken the parts or cause surface cracking. 2. Suits making moulds using wet lay-up. 3. Suits making moulds using pre-preg. carbon fibre. In this case the ASA plastic parts must not be heated beyond ASA softening temperature (>90C). What processing and materials would you advise?
