I would l ike to share with you a few pictures of 3D prints of a head, created each with a formlabs Form 1 and a B9 creator.
We love the idea of the B9, it's open source, and the calibration can be done by ourselves, unlike with the Form 1.
The ongoing printing cost is also lower with the B9.
However we are not so happy with the quality of the B9.
Whereas the DLP printed objects show the usual pixelation of the projector on the side of the head, it is only barely visible.
What however is strongly visible are lines along the layers. you can strongly see this on the forehead
This may be a problem of a miscalibrated z-axis of the specific printer it was printed on - and not a general problems of all the B9 printers. Tim Yoshi, who was so kind to make the B9 sample for us, allowed us to share his name.
So my question is, how likely it is that these lines appear, and whether other B9 owners experience similar lines, perpendicular on their objects.
Please note: since the resins used for both printers, the form 1 and the b9 were different, we spray-painted the samples with a filler-type of spray paint, for better comparison. The filler spray paint is supposed to fill tiny dents and streaks.
