Re: Anyone use Polycarbonate (PC) or PETG?

I haven't printed Polycarbonate recently. The early types required very high temperatures, but recent versions like the Ultimaker branded one is apparently easier to print. Both PC and PETG (Colorfabb XT) are hygroscopic and might need drying when the spool has been open for a while. PETG can be dri...

Re: Has anyone used NinjaTek Cheetah?

I think the ninjaflex cheetah is rather similar to the Ultimaker TPU95A, so it should work okay if you don't print too fast. I have been printing the TPU95A on the UM3 in a dual print with retractions and it came out okay. One should increase the retraction distance to avoid oozing though, which I d...

Re: Drying your humid filaments....

I have been drying my Bridge Nylon and other materials in an oven a few hours at 80 C, it works fine. This was a precise lab-oven though, if you attempt this at home make sure you have a precise thermometer inside the oven to check the actual temperature. PETG can also absorb a bit of moisture, but ...

Re: Black Belt Kickstarter

Printbot is apparently a bit ahead of Blackbelt with something similar, but less expensive: https://printrbot.com/shop/printrbelt/

Re: CR-10 vs Ultimaker 2+ Benchie prints

Interesting, zebra-bug that the Ultimaker machines suffer from under certain conditions is clearly visible here.
Do you know what stepper driver circuit the CR-10 is using?

This reminds me that I really should get a set of those TL-smoothers to test on the Ultimaker.

Re: UM2 to UM2+ print head upgrade

The I2K was invented in an attempt to increase the lifespan of the early PTFE couplers and to increase the maximum operating temperature of the machines. With the TFM, the lifetime of the spacer increased dramatically compared to the earlier PTFE and glass filled PTFE. For normal printing (up to 260...

Re: A Tea between friends :-) How was Your Day

@Anders Olsson what make of Woodfill are you using? I did struggle with Kai Pathy's wood fill although he did recommend a miniumum of 0.5mm nozzle, the modified Robert's feeder would grind the filament or deformed it as it was softer. although when I upgraded to the bondtech feeder it had enough pr...

Re: A Tea between friends :-) How was Your Day

Who said Woodfill can't handle retractions? :-P 2017-06-17-1808.jpg The only modifications I have done is a different feeder gear and another type of spring in the original UM2 feeder. Ambient temperature is 30 C and I am using a 0.6 mm nozzle. (0.4 mm nozzle just does not work with this spool of wo...

Re: How much should a good 3D printer cost?

There might be a market for a really high quality printer, but I doubt that you can produce and sell such printer for the same money as an UM3. Just have a look at E3D for example, the Bigbox printer was successfully developed and all their Kickstarter printers shipped and then they realized they ju...

Pff been so busy the last weeks... We built our house as a turnkey solution but I had no clue how much work remains after they are "finished" with it. Guys I need your advice: I'm demo'ing my 2 3D printers on a kids-tech-happening this weekend and the previous years I've always had them printing so...

Re: Cura 2.5. Why so messy?

Cura does all sorts of tricks to save printing time. What you see in your print is one of them which I think is not justified, since it saves very little time and the result is rather messy. It is called combing in old Cura and means that when the head has to move without printing, it moves over sur...
