Hello everybody,
I can not print my 3d pieces until the end, because the pieces loosing from the base…

the base of 3d pieces are not flat and only middle of the pieces is touching the base and the borders are above of 3dprinter’s base. and going out the base.
I do not know what happens to my new 3d printer. Can someone help me?

tks a lot!!

best regards,

Marcelo Fiori

Hey Marcelo,

Your print is shrinking as it cools and contracting, away fro the build plate. Are you sure that you are not using ABS, rather than PLA? If it IS PLA, it might simply be that the build plate is not set at a high enough temperature, or that the nozzle tip is set a little too high, relative to the build plate surface. The initial gap between the nozzle and build plate should be between 0.1 and 0.2mm.

Cheers,

Hi Andy,
Yes, normally I use only PLA material and also this settings:
nozzle 200c each
Build plate 50c

Have you ever had this same problem?

Tks a lot!!

best regards,

Marcelo

I’ve only ever had this problem with ABS and usually the opposite problem with Flashforge’s Buildtak surface. It’s easy to get it stuck so hard that you ruin the print getting it off!!

i’d suggest increasing tye bed temperature to 65 and make ABSOLUTELY SURE that you’re not printing with ABS.

Make sure your bed is leveled properly is always the first step to fixing adhesion issues. Next as stated by others make 500% sure your are printing with the material you think (I was adiment i was using pla but it was abs) it’s possible notater how many times you check so just make sure. Depending on your print surface the temperature required varies, so don’t be afraid to play around with it (I generally go in 5 degree c jumps then 1 degree once I get closer) Make sure no cold breeze is blowing onto your print. If it’s pla I know it suggests to make sure it is well vented, but rapid temperature changes will ALWAYS be a bad thing to deal with, I suggest for pla running the door closed but no top cover. (My personal tests show zero negative effects). ABS always run fully enclosed and I personally pre-heat the machine below print temps for 10-15 mins to let the enclosure get to an elevated temperature. Hope this at least helps a little.

#1. You need to get your nozzle really close to the bed for you first layer. It want so really squish that first layer.

#2. I have seen this when folks try to print with really cheap PLA, like no name brand from ebay. Usually is not pure pla, has other junk thrown in there. What brand PLA is it?

Make sure your fan is on, so that the part is cooling when the layers are being put down. But I am guessing it is cheap PLA.

100% chance of using cheap material.
Because, this material came together with the 3D printer … =((((

Tks a lot!!!
