As you said " the marketing bullshit and flashy videos" sucked me in so bad numerous years ago, I purchased one and another one the next year and additional ones again. We run them all day at a very low cost of operation and at a failure rate no higher than any of our other technologies.

Al Siblani at Envisiontec must have put a spell on me:) Thanks Al, the spell hurts so good

Firstly don't believe the marketing bullshit and flashy Envisiontec videos saying how their systems build pixel by pixel rather than layer by layer thus eliminating build lines. We run a Perfactory here and the build lines are less noticeable than some of the other technologies we use but they are still there. You can build using either 25 micron layers or 50 so building with the thinner 25 micron layers will help.

You say that you're looking at getting 'another' high res machine from which I draw the assumption that you already have one. John Makes a good point about the skill level required with a perfactory so it will make a difference is this is the system that you are currently using as you will already have this expertise. Failing that it does take quite a while and lots of wasted builds before you finally manage to 'tame' the system.

Depending on the resolution you're looking for, Objet could be an option but despite even thinner layers (16 microns) the build lines are if anything more visible than the EnvisionTec's this is because the layers may be thin which looks impressive on the specification but the alignment between layers is not sufficiently controlled meaning that side walls end up as rough and uneven as my mother in-law's chin.

Good luck.

Well, if anyone has the skills John does. It was my understanding that perfactory was working on algorithms to "blur" the buildlines or bridge them so to speak. I remember reading somewhere that the buildlines were still there but less obvious. I do not know if the changes were just tests, implemented or what.

I was able to play around with a projet and remember that parts were nice but there was still noticeable buildlines based on orientation.

Just my 2cents

I'd offer your customers what they want, the resolution/surface finish of the Perfactory Multi Mini with ERM surpasses all other technologies. A possible downside is you will need a higher level of skill to do it properly.

We're looking at adding another high resolution machine here at Moddler. We've been looking at both ProJet and Perfactory printers to better service our customers who create small models with copious amounts of detail and want output free of build lines. Most of our customers prefer Perfactory output due to the high resolution and superior surface quality.

But I wonder if our customers prefer Perfactoy output because there are more Perfactory bureaus than ProJet bureaus. It's a chicken/egg question: do service bureaus not use ProJets because there is no demand or is there no demand because service bureaus don't offer ProJet parts? Are companies gunshy about buying the successor to the Invision printers? Or are there other reasons?

I would be very grateful for any input you have. And I'm happy to receive your comments directly.
