Can Pro jr 1.0 do PETG?

Postby GiantRobot75 » Sat Jan 06, 2018 9:29 am

Can the hot end get hot enough to do PETG on the Davinci Pro Jr 1.0? I love the simplicity and design of the machine, I got it as a gift but if it only prints in PLA I feel like it’s the most restrictive printer on the market. If I can only print in PLA I really don’t see me keeping this machine. With the things I’m printint PETG and the size of the Davinci is perfect so hopefully it can, even if someone could point me in the direction of aftermarket add ins if it can’t. Thanks

According to their product line up, yes. It should be capable of printing petg. Look under products on xyz website. I would start by getting the hang of their product before moving to other brands. The quality varies to much to get an accurate feel if what it can do.
Also post back here. You know it's hard to find info on this stuff, here. We need the effort to put more info in a localized spot so post your results. Thanks

I received my jr 1.0 PRO day before yesterday. I printed over half of the original pla (including printing myself a new spool holder). Sadly my printer game with bit bad z-offset. That means that pla prints stuck very good to bed but had a bit of an elephants foot. I am messing with the settings bit by bit. Yesterday evening I tried to print with Spectrum's PETG (230-255) with printer on 230C. I printed couple of 2cm by 2 cm cubes. Printed bust of Batman. Came out really nice. Had a bit of a problem with hanging filament under the nose but nothing too problematic that can't be filed down.
One thing to look out for: I don't know if it still prints too close to the bed or quality of the Tesa brand masking tape I used but bigger petg prints (batman bust) was really hard to get off the bed. Finally it game with the tape. One thing I will test in the future with petg is maybe using bit glossier masking tape.

Previously I have read not to use the glossy tape, but if your prints are sticking that well, it may be exactly what you need. There's no one shoe fits all, so I think it's great your posting, talking about your experiences.

As soon as I saw the response to the OP that said "yes you can", I went to Amazon and bought a cheap spool.

I gotta say I've found my new favorite medium. While I'm still refining my print game, the prints are coming out cleaner, and they seem quite a bit sturdier. The plastic is a harder plastic than the PLA (I noticed this morning that one of my prints really felt like lego's - even though they are ABS).

I have a funnel I built for dumping coffee grounds into the filter cup without spreading them all over the counter (my coffee grinder wasn't well designed). When I printed it with PLA, it came out a bit flimsy and running tap-hot water over it softened it enough to be manipulated. It got particularly warped when my wife ran it through the dishwasher.

Printing another one with PETG, it does *not* soften with tap-hot water, and the coffee doesn't "stick" to it as much.

One thing I thought interesting after reprinting my coffee funnel, was there was a lot of "floss" around the print head. I'm sure this is a side-effect of what my settings were, and the duration of the print (I set it to as fine a resolution and as solid a build as I could, and it took 8 days to finish). You might want to regularly check your print head for "fluff" or even plastic starting to build up.

Because of some of my poor print-game (ugly bottom side of overhangs, in particular), I'm starting to get into mold-making and casting. So far, the results for that are fantastic.

One thing (as mentioned before) is that it's easy for the PETG to stick to the bed "liner". With the print I took off this morning, the print bed tape I used was actually melted to the bottom of my print.

With Cura, I have the ability to adjust the temperature of the lower layers of my print - I'm going to try dropping the temp for those layers to see if that will keep it from sticking.

Edited to add:
When it came time to change back to PLA, I found that there were PETG remnants that required cleaning out the extruder.

@prontor - that's a question better posted to the list in general, rather than at the end of an existing thread.
