Why does my 3D printer say no filament?

Why does my 3D printer say no filament?

Your problem is probably a clogged print core and you get the message from the filament sensor and if disabled, under extrusion. The sensor measures also the flow of the filament, not only if there is one or not. So you should clean your print core regularly with some hot/cold pulls and everything will be fine.

Is PETG always clear?

PETG becomes transparent when the layers completely fuse. Translucency is from incomplete adhesion or voids left. Try small increases to flow or print width to get slightly better fill – or slow the speed (but speed might not affect how much material is output).

Why is my PETG print brittle?

The part cooling fan. PETG is prone to being brittle if you apply too much cooling. Ideally, print PETG with no cooling for best strength.

Why is there no filament coming out of nozzle?

This can happen if foreign debris is trapped inside the nozzle, when hot plastic sits inside the extruder too long, or if the thermal cooling for the extruder is not sufficient and the filament begins to soften outside of the desired melt zone.

Can PETG get wet after printing?

As a general rule, wet filaments have less strength, so they break easily. Their impact resistance will decrease because the H2O molecules weaken the polymer bonds and lower their resistance forces. PETG doesn’t absorb too much water; Especially if you keep them in a low humidity place, there won’t be severe changes.

Is PETG filament brittle?

Very durable, it’s more flexible than PLA or ABS, but also a little softer. PETG is also very strong, it’s not brittle but can be scratched more easily than ABS which is harder. PETG plastic makes a terrible support structure, because it sticks so well.

What happens when you use PETG filament in 3D printing?

Sometimes blobs of PETG filament will stick to the nozzle and then end up deposited on another part of the print where it’s not supposed to be. If this happens it will cool and harden, which can be a hazard for the nozzle the next time it moves into that space. The result is usually a layer shift, which can be detrimental to the print.

What kind of printer do I use to print PETG?

I print primarily PETG and polycarbonate. Your mentioned PETG nozzle temperatures are super low. Attached is a zip archive with my PETG print, filament and printer settings. You can import them into PrusaSlicer to use them. Be sure to get all three types of settings imported and selected (Print, Filament, Printer)

What should the temperature of a 3D printer be to print PETG?

Using the Right 3D Printer. To print PETG, your printer must be equipped with a hot end that can reach a temperature of at least 235 °C. Ideally, you’ll want to be able to reach about 265 °C, but 235 °C may be sufficient for some PETG filament. Keep in mind that every spool is unique, and may require a slightly higher or lower temperature.

How do you clean the nozzle of a PETG printer?

The nozzle can be cleaned by running a dozen or so cm of cleaning filament through the extruder (at higher melt temp of the two filaments you are switching between). Alcohol wipe down is insufficient for 1st cleaning between different plastics.
