Re: First Time Casting
Your problem looks like ash. Possibly bad curing or bad burnout. I think burnout is the most likely. First you need to make sure your oven reaches the Temp. that you have set. Sometimes, especially when the coils get older, wont reach the set Temp. So maybe you have set the oven to 750C top but if ...

Re: First Time Casting
Is it possible to try cast B9 Emerald so we can rule things out? Certainly, I have some old B9 prints laying around I can cure and cast. I should mention I used B9 Emerald to begin with, then after about two years tried EasyCast HD (brown) and love it. The castings from my casting house very slight...

Faulty Resin VAT/Tray?
Both of my VATs are degrading by themselves. Notice how there is swelling around the orange plastic section. It seems to first swell, then crack later. Is anyone else having this problem? I haven't dropped or mis used them in anyway, I have gone over my procedures with the reseller before, nor have ...

I araldited mine back on and have zero regrets... During an overnight print the glass managed to pinch the film and in the morning I found the VAT empty with a puddle of resin around the base of the printer.. It was a massive pain in the ass disassembling the printer to clean the resin out

I have a Vivitek and am using Easy Cast HD and I h...
