It should work with PLA if you use the Up-brand PLA filament. Other brands, not so much (without modification).

Re: New desktop 3D printer from Tiertime

I really hope it's not a smaller form factor. Seems silly to increase the build volume so dramatically and then reduce the spool size - you won't be able to do a big print without changing spools in the middle! The thing I'm most worried about is that it might only accept a certain size spool. It s...

Re: New desktop 3D printer from Tiertime

I'm not sure what to make of the video--it's not clear that it's even a real unit (vs. a rendering).

With luck, someone who knows the Up will see it in person this weekend and report back.

Re: How to access the bearings for lubrication

1) Remove the build plate by unscrewing the two screws holding it to the platform heating block.

2) There are four screws (one at each corner) holding on the cover to the part which holds the platform heating block. Remove all four of them.

3) The cover should come right off.

That's it!

Re: Printing round object

This is inherently hard with this type of printer.

Usually if I need a good-looking round surface, I try to orient the round surface so it's on the side or top of the print, not the bottom.

Re: How much plastic do you throw away?

I would guess about 15% to 25% of the plastic I buy goes into the trash bin, but when I first started 3D printing three years ago it was closer to 75%. Most of what I throw out is support material and raft, with just the occasional bad print. I'm not counting parts which printed perfectly fine but w...

Re: New desktop 3D printer from Tiertime

$1,900 for an Up with 255x205x205 build volume sounds like a compelling value. And out right before Christmas! For me personally, I've always appreciated the "semi-open" design of the Up, where you can easily mod the printer and use third party filament but not have to wade into the swamp which is o...

Acetone is likely to improve the adhesion, since it will remove dirt and oil that's accumulated on the perfboard.

Re: Office in USA?

You can order parts from Afinia (http://www.afinia.com/), since the Afinia is the same printer as the Up. They are located in the U.S., but the prices are higher than ordering from Up in China.

Re: Very difficult to remove from cellboard

I use a single-edged razor blade scraper to help remove the raft from the perfboard. Wear gloves, though, in case the blade slips. Don't want to wind up with stitches. Also, you can take your time cleaning off the perfboard: if you need to do another print right away, just put on a different perfboa...

Re: Anyone tried the filastruder homemade filament?

I've not tried it, but in general I'm very skeptical of any of the make-your-own filament projects. It's hard enough getting good filament consistency in an industrial setting, so I don't see how they've managed to solve the problem in a way that works at home.

Re: Another filament cooling mod

One approach I've wanted to play with is actually moving the stepper back by about 1cm and extending the feed gear somehow to reach the filament path. Like many others here, I've been gnawing on the heat problem with PLA for years, and it seems to me that the fundamental problem is that the stepper ...

Re: This happened last night

Whoa, how'd that happen?

Was the end of the filament somehow permanently attached to the spool? It takes a lot of force to rip the extruder off like that.

Re: Extruder problems

This can also happen if you have a bad batch of filament which has too large a diameter at certain points. This used to be common, but quality control has gotten a lot better at filament manufacturers the past two years. It can still happen, though. Check the filament for any visible bumps, and get ...

At the risk of sounding uneducated about this subject..

Re: Extrusion head stops and makes a clicking sound

Hi Drew, Thanks for the explanation about the varying size of the filament. So, if the tube above the nozzle is purely for holding the plastic before it gets to the nozzle to be melted, why not ream out the tube to be slightly oversize to handle all these differences? It would seem to me that makin...
