For a while I have wanted to be able to print higher resolution parts with my 3d printer and have more flexibility in adjusting the usable build area (XY build area size) so I decided to upgrade to a high … Continue reading →

I am able to move the projector on my DLP based 3d printer up and down in relation to the vat easily because the backbone of the printer is a MP4 heavy duty photographic copy stand. The projector is mounted … Continue reading →

Vat Stuff The vat is where the rubber meets the road. My 3d printers vat is made of .5″ (12.7mm) cast acrylic (not extruded).  Cast acrylic does not have locked in stresses, so when you clean it with a solvent … Continue reading →

The photos show a 3d print made on my updated dlp based 3d printer. The lines on the print represent well defined 0.1 mm layers.  The layers stand out because I printed the part at an angle to minimize large … Continue reading →

It started the way these things usually start, you decide to upgrade a part and then one thing leads to another which leads to another which leads to another…  In this case I wanted to have a vat that was easier … Continue reading →

One thing I have come to realize about this type of 3d printer is that what counts is that the build “face” (the layer that is being exposed), the vat floor and the projected layer image have a particular relationship … Continue reading →

Probably the most interesting part of this printer is the tilt assembly so that’s where I will start.  The basic requirements of the vat tilt assembly is that it tilts with enough force that it is able to peel the … Continue reading →

Please Note: I am no longer using this control setup, I have switched to using Marlin firmware and ramps 1.4 with an arduino mega 2560. I will post an article on this setup sometime during the week of 11/28/16 Any … Continue reading →

Close Focusing A DLP Projector: I have noticed that sometimes people building dlp 3d printers have difficulty making their dlp projectors focus close enough to create a small image on the vat floor. One of the method I have seen … Continue reading →
