FunToDo Industrial Blend
So I just had a bit of time to test out my Draken using some black FTD Industrial Blend. This was the first time that I've used any type of 3D printer as I've only previously had parts printed through a friend using his FDM machine... so I guess it was a sort of familiarisation print. Overall I found it to be quite simple once I ran through the steps and watched some videos about the DLP printing process. I realised early in the print that the projector was probably not aiming square on at the vat as I hadn't adjusted this but I let the print run anyway. As a result the print came out with a slight distortion (the top section came out with approx. 0.4mm variance in diameter).
The object I printed was the 50% scaled rook that @sbryan uploaded to GitHub.
- Loud Draken is loud.
- Projector was in the 3rd slot, and was set accordingly in CW.
- Left everything in their default settings such as the 50 micron layer height, 6.5 sec exposure times, anti-aliasing and the projector brightness was not adjusted.
- I'm not sure what to make of it as it was my first time doing this, but it looks like I need to lower the brightness of the projector to prevent the areas that aren't meant to cure from being exposed.
- Considering that it was most likely over-exposed, the details came out somewhat muddy (especially the "undercut" section that transitions from the middle to the wider top section). It doesn't look too bad unless you are very close to it though ;))
- The circular recess at the base has a strange amorphous surface instead of being flat. My guess is that some resin got trapped between the flat surface and the print bed and slowly cured as light bled through in subsequent layers? Or maybe because it didn't have any supports to keep it from from deforming when the tilt action happened.
- The spiral and stars came out very nicely, as did the flat surfaces on the top.
Overall I'm very happy with the result and I'm itching to dial in the machine and my brain properly so I can get some good results.
