|The 4 simultaneous copies being printed|
When I printed these - each of which is 30mm X 22mm X 4mm - I had some unexpected quality issues, which I am attributing to the simultaneous multi-item printing method. The issues simply do not occur when I print one at a time. This is a lesson worth sharing.
The Quality issues:
|Curled bottoms after printing|
- Curling at the bottom of the models (in spite of a heated bed). I've never had curling on prints before.
- "Globbiness" (there must be a technical term for this) on some edges which make them stick up or out over the edge.
- Gaps in the top layers which make the surface not only rough, but look more like a weave than a solid.
|Gaps and Globs visible in top layers|
|COMPARISON - one printed alone, vs. one of the bad 4|
I recommend trying multi-item printing in two's - figuring out an optimal level of efficiency without sacrificing quality.
