How do you temper PETG?

A good starting point is to anneal the PETG at an approximate temperature between 75°C (167°C) and 78°C (172°F), for a time of between 40 minutes and 80 minutes and then let it cool very slowly.

How do you make PETG smooth?

PETG can be smoothed with fine sandpaper, epoxy resin and paint. Similar to ABS with acetone, PETG can also be smoothed with dichloromethane. However, dichloromethane is very dangerous and not easy to obtain.

What temperature does anneal PETG?

For PETG, the suitable temperature is about 90-110 °C (194-230 °F). In this range, neither the warping or dimensional changes are too significant. At higher temperatures, PETG deforms gradually, up to 170 °C (338 °F), when it melts just like the PLA.

How do you melt PETG?

You can take off the nozzle and heat it with a torch until the filament melts and comes out; that simple! However, there are more options. You can also take a brass brush and clean the nozzle with it. You can also use a metal wire or even a nylon filament to clean the nozzle's hole.

What temperature should a bed be for a PETG?

Printing PETG requires a heated bed at 70°C - 80°C. We generally don't recommend heating your heated bed above the glass transition temperature of PETG (80°C ).

3D Printing with PETG - How does the printing temperature affect strength? || Setup

How do you keep your PETG from sticking to bed?

For the best chance of success, you will want to make sure you have a heated bed set to 65°C. Some PETG is more warp-prone than others, so higher temperatures may be required to give them enough adhesion to the bed. If you're having difficulty, bump the temperature up by 5°C at a time until adhesion improves.

Can you print PETG without heated bed?

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 melt 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.

Can you polish PETG with acetone?

Dissolving. Although we mentioned that traditional acetone smoothing doesn't work well with PETG, there are a number of other chemicals that are capable of dissolving and smoothing the filament.

Will acetone break down PETG?

Unfortunately, PETG does not react with acetone, meaning that it's not possible to dissolve or smoothen PETG with acetone by using any dissolving method.

Can you boil PETG?

Temperature Resistance

While most PETGs can withstand temperatures of up to around 80 °C, ABS can go until 100 °C. The margin is small enough that PETG will last in most electronics applications, but only ABS will survive boiling water. This is especially useful if you need to sterilize your print.

Will PETG warp in the sun?

PETG won't melt in the sun. Its melting point is 500 °F (260 °C), and the glass transition temperature is 176 °F (80 °C). Also, PETG is more resistant than other thermoplastic filaments to UV-A and UV-B radiation while being immune to the UV-C rays of the sun.

Can you microwave PETG?

Is PETG Microwave Safe? PETG is transparent to microwaves and has a high enough heat-resistance to sufficiently deal with microwave applications. PETP is the normal plastic within the group that is used for bottles and injection molding, but PETG still holds up very well.

Can you flame polish PETG?

PETg sheet can be flame-polished using a standard propane torch or a hot-nitrogen welder. Both techniques require accurate control of the distance between the sheet and the heat source; otherwise, surface whitening or excessive material flow may occur.

Can you iron PETG?

PETG irons fine, but there's an increased risk of extra filament sticking to the nozzle. This plastic might accumulate on the nozzle, get dark as it's overheated, and eventually attach to the print. The same goes for FLEX, but much more pronounced. ASA irons incredibly well, producing super smooth top surfaces.

Can you heat treat PETG?

Polyethylene Terephthalate Glycol (PETG) polymer is used to 3D print test parts with 100% infill. After printing, samples are packed in sodium chloride powder and then heat treated at a temperature of 220 ◦C for 5 to 15 min. During heat treatment, the powder acts as support, preventing deformation of the parts.

Can you epoxy PETG?

Epoxy. Technically, epoxy isn't a type of glue, though it's a great way to bond plastics, and it works fine with PETG. The versatility and durability of epoxy are usually more than enough for many applications.

How do I strengthen my PETG prints?

Can I spray paint PETG?

Painting with spray paints can give good results and a more uniform look. Like using a paintbrush, this method is best for models printed in PLA, ABS, and PETG.

How do you clean PETG nozzles?

How do you unclog a PETG?

I find it a lot easier to push some cleaning filament at 265C to melt any leftover PETG, let it cool then do a cold pull or three. Takes a few minutes of effort plus cool-down time, but it works well. Then, as long as it prints well, one could infer that the cleaning worked. By the way, this is a genuine E3D nozzle.

What speed should I print PETG?

PETG works best below 1.0 to avoid oozing. Print Speed: 55mm/s. Travel Speed: 100mm/s. Bottom Layer Speed: 30mm/s.

Is PETG harder to print than PLA?

PETG is also considered one of the easier materials to print with, though less than PLA. A major part of that is that PETG also does not need a closed chamber. However, due to higher temperature requirements, a heated printing bed is required for PETG, limiting perhaps the choice of printers for some users.

Should PETG be printed in an enclosure?

I almost broke the plate trying to get it off with PVA. You don't need an enclosure, but it should not be too cold an environment or really large prints will warp even with PETG. PETG likes to print hot. Even hotter than what appears to flow well.
