The level of detail the photon is capable of is INSANE at it's price point!

Currently printing while I'm at work. It was about half done when I left. Working on a special project for T-maxx body. Whipped up the sculpture in Meshmixer last night - first time actually trying to build a sculpted model like this from scratch in Meshmixer. Usually I make something in Blender in low poly then muck with it in Meshmixer.



No explanation need if you're cool...

And a little computer test coloration version...



Degenerate.

Printed - not half bad for a shitty little DaVinci Jr printer. Was a pain getting the supports out of the teeth area, wound up snapping a few off. This print was of a version of the model that was slightly less detailed than the previous post, so a few things(pock marks, etc) are missing.



Test print.

Slathered on a coating of 2 part epoxy to get it ready for painting.



Prepped for painting.

I sent another out for production at a 3D hub, just to see if it prints any better, but I'm pretty pleased with how this one came out and will paint it up tonight.

Some more pieces of the puzzle for printing out tonight. The headers I sculpted, the engine I snagged somewhere for free. These are going to be used in different ways, as part of a form for vacuum mold, except the Fink, which will be painted and housed in a bubble.

I just printed a test cube that is within .01 on all 3 dimensions. Not bad for starting out at about .4 on each dimension. This cabinet that I added allowed me to calibrate each axis very well and hold the tolerances.

It wasnt in any directions I found in the manual but if dimensions are off the suggestion is to calibrate the stepper pulses to mm. I had to get a slicer with the ability to manually issue g-codes and change the per axis value in steps to mm. It was off by .02 per mm which ended up at about .4mm per 100mm. All better now and my slicer of choice CURA doesnt need every model modified to be pretty close to what was expected,

Refined Rat Fink
Made some refinements to the rat fink mesh.

My question is, I'm having great difficulty with the supports. They are really tough to remove without destroying the print. I had farmed one out too, and that one came back perfect, but I'd really like to get my settings working correctly. I know I'm probably screwed because I'm using a Davinci Jr, but the prints looks great, just the supports are brutal to take out. Anyone have any tips for best settings for a complex mesh like this?
[edit] Figured it out, printing it lying on it's back uses very few supports in the mouth area where I had problems.

Im not a pro but you might want to look into getting your machine bridging better. Some combination of heat and fan that compromises strength but also gets definition. Small breezes made it tough for me until i put the machine in an enclosure. Pauses and print speed are part of the mix as well.

Your monster truck body and ratfink art are crazy good. You do some great modeling and post production work.

I don't print many complex parts but when I do supports I usually skip 2 layers on the z and a few more on the x/y to help get the supports off.

Thanks!

I was able to tweak settings and also get the best angle for the least amount of supports. This was so much easier to clean up, though both arms snapped and had to be glued back on, I attest that as much to my crappy little printer.

Printed and prepped for painting.
