3d printers question

[TECHARTISAN]

Im much happier melting away supports. I appreciate the resolution that light cured systems can reach but I cant deal with support scars. I just wish I could print wax as fast as acrylic.

It has a tiny build envelope and can only get down to 50 microns right? I wouldn't print at that resolution for dental.

A lot of these 'DIY' envisiontec style printers have resolution lower than 50, lower than 30, down to what I've been told is 10 microns. I was reading that some simple adjustments to the projector (distance??) is how they adjust it but I have no idea.

Anywhoos, what do you know about CLEAR ALUMINUM though and how Airbus is planning on 3D printing planes made from this type of thing ?!

We have no problems with flash when casting our prints from our Projet. We use Bego's investment the Bellavest SH, and burnout at 1550 for a minimum of 1.5 hours and 10 minutes added on per ring.

What type of casting machine you using? We are using the Bego Nautilus CC Plus induction caster.

try Anaxdent investment. anaxVEST pm.
Best e.max press i have ever seen out of the p3000. no reaction layer or fins and it was with printed resin.

Hollow out thick areas on pontics. (Digitally)

Have Stage I burn-out HOLD at 800F for 1/2hr, then go to full temp whatever rate you want.

Helps to reduce forces/pressure on the investment from plastic-wax thermally expanding before it actually flows out.
