Bought an UM3 - what's with the print quality

[monomonster 0]

Hello all,

 

New to the forum but not to 3D printing. I bought a used UM3 a couple of days ago, did some cleaning and maintenance and was ready to print my 1st object. The previous owner gave me a number of original UM spools of PLA and PVA and from the popping sound while the PVA was printing it seems like the spools had moisture in them so I had placed them in a closed container with a dehumidifier for 24 hours.

 

Here is what the 1st print looks like. 0.4 nozzle, 0.2mm layer otherwise defaults in cura. The print is OK but not really good as the bottom looks pretty bad and overall the quality is not what I had expected. Do you think this is a material issue or some calibration is required? I used all defaults in Cure when slicing this.

Did you have support enabled when you printed that part?

 

I always enable support interface. prints a solid slab which improves surface quality of suported areas.

Depending on what support material used you might need to vary distance between support and part.

Zero if using PVA, more if same as print. Below example is supporting TPU with PLA
