TAZ 5 and 1.75mm Filament

Post by wantmys2000 » Sat Mar 07, 2015 1:25 pm

NOTE: I am pretty sure the following is not going to be supported by lulzbot.

I recently received my new TAZ 5 and have been very pleased with it, but like others I have a buttload of 1.75mm PLA filament from my previous printer. I figured that the new Hexagon hotend on the TAZ 5 was all metal and did not have the PTFE tube what would be the problem with just sending some 1.75 filament through it. I figured that the main issue would be with retraction, but I am happy to say it worked perfectly.

I took my standard PLA profile and just changed the filament diameter from 2.89 to 1.75, then print a calibration cube. When loading the filament I did not adjust the extruder tension at all. It was dead perfect, wall thickness was dead on, dimensions were dead on, no blobbing, no holes.

Since I tried this I have run full print plates with 1.75mm PLA through the TAZ 5 with zero issues. So for all those out there that have some 1.75mm PLA sitting around, don't be scared to run it through.

I have not tried this with ABS or any other material as I primarily had PLA.

Hmm, interesting... I'll have to give my 1.75mm ABS a try.

Thanks for experimenting and sharing.

For those that are interested, here is the Roctopus print at 0.075mm layer height in 1.75mm orange PLA. I made no changes to the TAZ 5 or the hexagon hotend. I only updated my standard PLA profile to set the filament diameter to 1.75.

Nice print... Interesting that the thinner filament puts enough pressure on the heat chamber to push filament through accurately without overflowing. Do you have retraction on when slicing?

Yes, retraction is on, 1.70mm. I do notice it takes a little longer on the skirt to get a full width line, maybe it needs to fill up the chamber a bit more.

Wow! what a really awesome advantage this is for the hexagon hot end! I never thought about it!

FWIW, we tested this on a couple parts in R&D and were able to print fine with 1.75mm filament on a 3mm setup. Results may vary.

I'm gonna have to test this, and I'll be very happy if it works :D I kind of got obsessed with 3d printing when I purchased the davinci 1.0 in november, and bought a massive amount of 1.75mm filament. I think I have 13 rolls :lol:

You'll be impressed 8-)

We've been running all sorts of 1.75mm filament in R&D and marketing and it's truly impressive. Softer filaments like nylon and PET can buckle and jam occasionally, but PLA, HIPS, ABS parts are virtually indistinguishable from 3mm printed ones. So that's pretty awesome :)

So far we've been able to get great prints in cura turning the filament size down to 1.75, but no other changes are needed. If you've got some 1.75mm filament around, give it a shot and let us know how it goes

Cheers
