New UM2 random under extrusion problem

Recommended Posts

OK so I recently got my UM2 and have been trying to get some really great prints, unfortunately that has really just not been happening :,(

So my main problem is that of under extrusion, It will just randomly under extrude for some parts of my prints like IMG 0643

and these little artifacts that hang off the sides

IMG 0648

I print pla at 220 at .1 mm at 60mm/s also tried 210 and 226 same results.

The tension is at the lowest setting and the back is clean, no filament fillings filling it up.

 

I tried printing the part that was under extruding (the bars) and this is how they came out:

Any help would be appreciated.

 

I also tried printing out a marvin and got a pretty rough result

image1

I printed him at 205c and he looked a little better(less melted) but part of his foot was under extruded and he still wasnt that great.

 

I have done the atomic method a few times so I don't think it's a blockage.

My bed is pretty much perfect, never had a problem with adhesion and everything seems to be very flat. I reprinted Marvin at 50% speed, had a lot of trouble bridging this slow you can see it in the hole on the top, printed around 205c.

I use the filament that came with the um2, tried temps from 205 to 230, all give random under extrusion or other problems.

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
