Pet+ as a good alternative to ABS

[kanningphish]

And, how does the pricing of PET+ compare to ABS and PLA?

Jim, I am so glad you turned me onto PET+. I've been printing pretty large parts for 3 days and not a single failure. They come out great, no warp and are just fantastic. I'm really glad you suggested it to me.

I personaly also like the PETg from Colorfabb,
Its the only PET i used so far but it works nice ^^

XT series so far i know,

Also first time i did my jhead on 240c, i guess i shouldnt put it on 250 tho :P

Thanks rob. It really is nice stuff. I really think that once more people discover it it will become a more standard filament and not a specialty filament. As my abs runs out i know i am replacing with pet. Eventually thats all ill be printing with.

Luigi, i know someone who has been using the xt for awhile and they have good things to say. They did make a change in the formula not long ago. Im not sure why but the person did say its more difficult to use now than it was before the change. I dont know what the change was. I have yet to try it myself. I would like to give it a try just to compare to madesolid's. Made solid has so many colors available now though which is nice. Only so much you can do with clear but i would think that colorfabb is more available in your part of the world.

So is it true that pet+ has very little odor while printing?

I detect no odor at all. I'm in a small room and never smell anything.

[jimc]

yes no odor at all that i can detect

And almost no warping, which mean no enclosed chamber needed?

I guess the main drawback is a high temp nozzle, which would require nylon-capable setups.

I've found that Pet+ "can" warp significantly so I can't endorse the "almost no warping" feeling. I printed a part last week that was 4" wide, 6" long and 2" high and it warped off of the bed a full 1/2" on one corner. But, that's just my experience. I don't have a commercial enclosure but I do have a makeshift one to control envelope heat and keep drafts out. So beware, warping can still be your enemy.

Fortunately, I don't think you need exotic setups to use the higher temps required. They aren't that much higher. I have a Makerfarm i3 with a basic Magma and JHead. Both heads print Pet+ perfectly. You may need to raise the "overtemp" setting in Marlin/RAMPS so the overheat threashold does not trigger a shutdown. There are posts here in the forum about that so I won't go into it here.
