I was told you were the resinfags by /diy/.

I print videogame console enclosures so feel free to ignore my question if it's not related enough.

I'm looking to get the same results I get from ordering prints from PCB way at home.

I have a UniFormation GKtwo and I use Siraya Tech resin.
My prints are sharper than PCBway's but mine are brittle, screws shatter any posts I try to screw in to but my prints have sharper corners but are less transparent, I don't mind losing some transparency but I would want to tint the resin dark.

I'm considering printing flat to get the best bottom/top surfaces but I'd need a printer that can handle 150mm, at present I'm printing at an angle and sanding.
What can I do to get the same results as them?

I'm considering another printer (build volume I'm trying to print is 150mm). What can I do to get the same results as them?
I'm happy with parts being darker and matte.
