Re: Flashing issues

True but it also contaminates your resin with tiny little flakes of the cured resin peeling off from the flashing. Looking closer at your last photo, I do see a lot of small debris on the build plate. Did you filter your resin before that print? The only real solution is to back off the bottom laye...

I wouldn't worry about that, since it does help make sure the print stays secure to the plate. ;)

Re: ResinWorks EasyCastHD castable resin

For Dust2Dust, I have one of the Paragon SC kilns with the fiber muffle and when I tried to do the fast ramp with the button up, I could see through my window that there was the water from the investment boiling and throwing splatters of wax along the walls of the muffle. That caused it to turn blac...

Re: ResinWorks EasyCastHD castable resin

A customer told me ResinWorks recommended a straight ramp up to 1425F, holding for 3-4 hours and then down to casting temp, which worked well. We haven't tested this burnout. I think that is very similar to the burnout recommended for Prestige Optima investment. The only thing I don't like about it...

Re: Erics paper on resin casting at the santa Fe Symposium

Not all resins react the same to the microwave in oil/boiling water method, so it isn't a one-size-fits-all solution. I guess having some sort of empirical testing to back a claim always goes a long way to supporting said claim. The lay-man doesn't know much about the cured resin chemistry and how t...

Re: Infocus projector bulbs.

That was a factory bulb? I thought all the OSRAM bulbs had engraved lettering in the ceramic holder versus printed? I've seen pictures of both on Google.

Re: New Solus

Only if the resin can support that resolution. The flip side is that you can have 20ish um resolution on a larger build area, which is pretty nice too.

Re: SolusWax Tips and Tricks

IPA reacts with resin , all resins , its best to clean the uncured resin off but remove the IPA right after that asap because the reaction continues to occur until the ipa evaporate completely and that reduces your chances for success , I believe it penetrates the surface layer of the model that ca...
