How do I stop PETG blobbing?

How do I stop PETG blobbing?

Less over-extrusion means you should see less blobbing, smoother z-seams and reduced stringing. This means you can reduce time-consuming extruder moves during the print. I find I can get by with 0.4mm retraction (often less), 0.4mm z-lift and no wiping once I calibrate my filament settings.

Is PETG waterproof?

Because of the very good layer adhesion, the PETG prints are suitable for waterproof applications.

Does PETG need an enclosure?

Overall, PETG is generally very easy to print with, as it requires no enclosure nor heated bed, making it compatible with virtually all FDM printers. It combines ease of printing with great strength and durability, making it a great filament choice for any print.

Does acetone dissolve PETG?

It dissolves freshly printed PETG (and glue parts together) as well as the residues on the print nozzle. Side notes: Acetone is wellknown for being absolutely useless for dissolving PETG and I can confirm this from my own experience. All you can expect is to roughen the surface a little bit.

How do you remove moisture from a PETG?

2 Answers

  1. Preheat your oven to 160-180°F (or 70-80°C).
  2. Place spool in oven for 4-6 hours.
  3. Remove and place in an airtight container, preferably with desiccant. 5-gallon buckets with airtight lids from local hardware stores work very well for filament storage. You can use uncooked rice as a cheap desiccant.

Is it OK to use PETG on glass?

PETG is known for sticking well to the bed; so well that it does not need a heated bed. If it weren’t for printing other materials, I would try printing directly on the glass bed instead of a build surface. However, the build surface may help protect the glass from excessive force.

What kind of glue to use on a bed?

To increase adhesion for prints with smaller footprints, like the teeth of a gear, use a thin layer of PVA glue stick. Though it’s the ideal surface for nylon filaments, Garolite is a highly durable bed surface and is also compatible with PLA, PETG, TPU, TPE, ASA, and ABS.

What is the best technique to improve removing PETG?

It is easier to remove the skirt and brim by heating the bed up to 90 °C, so that the PETG is soft. However, if one tries to remove the printed object at 90 °C, the printed object is like to distort and ruin. I did sharpen the putty knife on the top side only.

What kind of glue do you use for 3D printing?

Garolite doesn’t have that problem and is able to successfully hold onto nylon and nylon composites with ease. To increase adhesion for prints with smaller footprints, like the teeth of a gear, use a thin layer of PVA glue stick.
