The problem is after they cool down. The flat pieces then start getting bend to them.

I have an airbrush (very small spray gun). Would that work for a urethane primer?

When assembling larger pieces together, I am often finding bending as the PLA strands cool.

Is there any safe way to anneal the PLA to relieve that stress?

Does anyone have any primer recommendations for PLA? (any not to use?)

I am doing ship modeling. 1:350. Have build my own parts. I need to get rid of the line patterns. The lines are small enough that it looks like some kind of primer would do the work for me.

I had been using the default settings on the latest version of Simplify. I reprinted the 6 hour job and the part came out fine. The setting that worked: Extrusion Multiplier .93 Extrusion Width: Manual .4 Layer Height .1 Outline/Perimeter Shells 6 Interior Fill 15% Outline Overlap 15% Minimum Info L...

I am using an M2 with Simplify to create essentially a box. I have made the bottom 1/8" and the walls 3/32"

The bottom is solid.

The walls are spongy and crack.

Is 3/32" too small OR is can I fix this using settings?

Thanks.

My hot end is clogged. I have disassembled.

However, part of the filament extends from the hot end into the drive assembly, forming a locking pin.

I cannot remove the hot end from the drive assembly to clean it out.

How do I remedy that?
