I'm not familiar with BJB metal filled epoxy as I'm in the UK, but I use similar product called EP426, EP426. Are your pieces particulary small/thin? At the price I see on their web site I'd definitely be calling them and asking why it's not performing.I have read your suggestions and will attempt to do similar. I too have been trying to make bucks w/o having to have them cnc on aluminum which is way too costly for the small production runs I do. I have built my own machine (its a variant of the HobbyVac) where its 220v 12x24 which I use to produce various car dash panels for gauges... I am having the buck positive printed now (was going to use silicone mold and then try various substrates until I found one that would not warp. I used a silicone mold and some BJB metal filled epoxy resin and it still bowed up after first use.. I need the bucks to lay flat on the platen. I also do not use a tank in my machine, the two-stage 12cfm pumps pulls near 29.7 direct, although I do find myself changing the oil quite often. thanks for the suggestion. can't wait to try it all out.
