Experience with new UM2+

Recommended Posts

Hi guys

Wanted to share some experience on my new UM2+ after 560h of printing.

I operate a few UM2s and after approximately 200h of printing I have to exchange the PTFE coupler with a fresh one (30% glass filled). Otherwise; Underextrusion. Apart from that, no major problems. Printing all sorts of materials but never mix on the same machine.

For the new UM2+ underextrusion has occurred for the first time after 560h. The new TFM PTFE bushing still looks OK so the cause mighty be found somewhere else. In any case I exchanged the bushing for a new one (not TFM though, still have to source the material).

When taking apart the head I noticed that the cylinder which replaces the spring was not installed properly; it was misaligned due to a very tight fit. The TFM coupler had also been squeezed heavily against the nozzle, properly due to thermal expansion.

But have to say; a very good performance improvement. I believe it is save to say that Ultimaker listens to people's feedback. Awesome.

I use active cooling for the feeders on my old UM2s, so I will not be needing the upgrade kit. But I will upgrade to the new coupler in combination with the constant distance spacer.

Cheers

    • 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.
