why ??

Thoughts? New pkg of Utimaker PVA. I have used 2 spools in the last 30 days with no issues like this. Same or similar models and settings. Bruce

I just open a new pkg (Ultimaker) that i just received and to straighten it enough to feed into the feeder is a test of patience to not break it. PLA, bends easily.

PVA is brittle for sure and overnight usually dissolves all of it or running water over it speeds it up

No errors.... while it was printing, I was scraping off PVA material from the top of the smaller bowls. I'm guessing that I pushed the table down and it started printing in mid air. I was bored 😞 How about the PVA over extruding on the bottom of the bowl causing the dug out defect on the print? I tilted the next print and it just moved the defect to the opposite side of the bowl.

after 25 hours of printing, the black nozzle goes bizarro!! Thoughts?

Its a proprietary model 😞

Yea, I just removed it and started a new roll. For less than 50 cents in material, it's a no brainer 🙂 Thx

Pics showing clean and then the PVA starts building on top of the print.

Thank you!

I cant do that because there is a key hole in the back of the part. You can see it in the pic.

I'm finishing a spool of PLA and want to know the best way to start a new one? Do I need to remove the filament before the end passes the feeder and dispose of the 2 feet remaining?

Can anyone tell me why the support material is printing on top of the saucer shaped surface? It makes the surface rougher ..... I added a couple more pics to show at what point this starts happening. I would think its a setting?

I'm printing some tiny round pyramids and after several tries I have good looking prints except for the thread artifacts on the leading edge of the print. The right one is offset to allow the fan to blow on the other 5 pcs to cool them. I attached the settings. Any thoughts? Thx

why is the filament coming out between the 2 back prints?

much better! Fan is on the front so I spaced 1 pc in the back to allow the fan to blow on the other 5. There is a small about of clean up, but these will be usable, Thx

I have a small round pyramid shape 1/4" diameter x 1/4" tall. The top tip is not coming out good? Ive tried slow and fast. pic is solid print.

some dealers are selling as 2.85 mm (3 mm) .... confusing! Are they just rounding up or is it 3 mm being sold as 2.85 mm?

Ultimaker 5S - Will I have issues with the 3 mm ?

We are a foundry and all our patterns have been cnc milled and sanded smooth so that the castings are also smooth. The lines will show up on the casting and OEM companies will not approve them aesthetically. The body filler spray works well, but of course extra time added. Im printing the attached now at 1mm @ 45 speed and the lines are not good. I will look at the things you mentioned, Thx

Here's one set which is about 5" long

Yes I meant PLA..... I couldnt change it after posting. The pics are what I want to achieve. I can't have any lines or they have to be very small. Currently I spray prints with body filler spray paint and sand off smooth. I don't know what an ideal layer size or print speed is? Does PLA give the best finish or another material? Im doing a print now on .1mm @ 45 print speed. I'll post how that turns out.

what are the best settings to use to get the smoothest surface finish?
