@KennyB: I had only one issue and that was coupling the camera tower to the scanner body but Uriah has fixed the tower stl a while ago so it should be a non issue. Otherwise all pieces fitted remarkably well.
@n2ri: From what I read, ABS has by far the most noxious fumes, PLA is better than ABS and PETG (same plastic as most food containers) should be better than PLA, however I am not sure about the science behind those statement I read, so it is aneddotical at best. I, most definitely, would not stick my nose on the printer and breath any of these products fumes and if possible ventilate the room the printer is in.
@bastien: The brand of PETG is eSun, in the US I bought from an online company named intservo 3D for ~ $34 for 1Kg spool. Printed at 210C, 80C for the heated bed, 0.2 mm layers, 50cm/sec speed and 30cm/sec for the first layer. Fans were on at 50% after the first layer. I used a brim on the larger pieces which when removed on this particular material did not leave any visible scar.
I tried initially to print the scanner using ABS but I had very bad warping and adhesion problems. I admit I am totally inexperienced on using ABS as I always used PLA. Printing this scanner was my first ABS attempt. I found PETG as easy to print as PLA but the feel of the printed part is similar to ABS. Now I have a full spool of ABS that I would like to put to a good use, so I am getting a new glass bed to use just with ABS and give ABS slurry a try.
If you would like to try PET from this particular brand keep in mind the available filament colors are close to semi-transparent, maybe the right word is translucid, not quite see through but almost. You may or may not like this kind of finish.
