Exposure Tests

I ran some exposure tests last night. I placed a small amount of UV resin into a plastic sandwich bag and laid it flat on the Resin tray. I went to a middle layer slice of a model slice and I let the resin expose for approximately 30 seconds.

Exposing the Resin to the projected image

As you can see, the resin set into the slice of the projected image. Exposure time took longer than I thought it would, and the resultant piece was still very soft and rubbery. I think I'm using a non-optimal UV resin for this printer. (I bought a quart over 2 years ago from www.solarez.com that was meant for surfboards). I need to bite the bullet and invest in a small quantity of of resin that is specifically designed for 3d printing.

The resultant created object.

If anyone knows of a site where I can purchase a small (quart or liter size) amount of UV resin specifically designed for 3D printing, please let me know.

Initial Alpha release of software

Well, I felt it's time to share the initial software release of my "Creation Workshop" UV DLP Slicing and control software. Any feedback would be greatly appreciated. You can download the initial release from GitHub here : https://github.com/Pacmanfan/UVDLPSlicerController/tree/master/UVDLP/Published

3D UV DLP Printer progress

I've been working on a new 3d printer lately. It's a 3d UV DLP printer that uses a photosensitive UV resin to create high resolution models. I've made some good progress lately and I wanted to show some results. I made a posting earlier to Thingiverse, sharing my first alpha build of my slicing and control software. You can take a look at it here:  http://www.thingiverse.com/thing:40778 . I've also gone ahead and posted the source code on GitHub here: https://github.com/Pacmanfan/UVDLPSlicerController . I've very proud of the slicing and control application that I've created. Getting the slicing to work correctly and handle all the special cases was no easy task.
