What is PETG good for?

PETG is the perfect filament to combine strength and ductility, which is why it's used in so many mechanical parts and robotics. It has great chemical resistance with good water, acidic and alkalic resistance. PETG is also makes a great material for artistic prints like bracelet, rings, collars etc..

Is PETG better than PLA?

If you are looking for a material with good physical properties, then it would be better to go with PETG over PLA. Unlike PLA, PETG is water-, chemically- and fatigue-resistant. It is also more durable than PLA as well as less stiff. Generally, PETG is seen as a mixture between ABS and PLA.

Is PETG stronger than ABS?

For most people, there really isn't a reason to choose ABS over PETG. PETG is stronger, more durable, and it prints better. It's also available in transparent colors. ABS is only necessary if you absolutely need the 100 °C temperature resistance or its ability to be glued and painted.

What is PETG and where is it used?

PETG or Polyethylene terephthalate glycol is a thermoplastic polyester commonly used in manufacturing. The PET component is what is commonly found in plastic beverage bottles and food products.

Is PETG good to print with?

PET and PETG filaments are known for their ease of printability, smooth surface finish, and water resistance.

Things you should know about PETG

Will PETG stick to glass?

For PETG we recommend first trying the surface your 3D printer was designed to use. Recommended - Straight on glass bed with a thin layer of Magigoo Original or glue stick. [2] - PETG can stick to glass, printing surfaces and sheets very well, sometimes too well.

Is PETG worth the hassle?

PETG is a little more expensive, however worth it, as it is strong and easy to use. I normally print at 220°C on the nozzle and 80°C for the bed. PETG has more flex to it so when you are printing parts it is less likely to break under pressure like ABS.

Is PETG water resistant?

PET-G. If you are printing a 3D model that needs to be watertight, then consider using PETG (Polyethylene terephthalate glycol-modified). Not only is this 3D filament water-resistant with a strong water and moisture barrier, but it is also a very easy material to print.

Is PETG better than acrylic?

PETG is a great choice for machine guarding. It is much stronger than acrylic but does not have the impact strength of polycarbonate. The cost is usually somewhere between acrylic and polycarbonate. PETG provides excellent toughness, gloss and chemical resistance.

Does PETG absorb water?

When not in use PETG should be stored away from sunlight and in a resealable bag with desiccant. Like many other plastics, PETG is a hygroscopic material, absorbing moisture from its surrounding environment.

Will PETG melt in car?

Will 3D Printed PETG Melt in a Car? If you need a model that will be placed in the car, PETG should last longer, but it really doesn't mean that it won't melt in the car. PETG 3D printer filaments have a melting point of about 260°C.

Is PETG good for mechanical parts?

PETG is a very tough material with good thermal resistance. Its use is universal but especially suitable for mechanical parts and both indoor and outdoor use. PETG has almost no warping, so printing large objects isn't a problem.

Can PETG be painted?

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.

Is PETG safe for food?

Food Safe PETG has a heat distortion temperature of 70 ºC and vicant softening temperature of 85 ºC, this means that, unlike PLA, most 3D printed parts using this PETG material can be cleaned in most home dishwashers even without annealing the part. Features: True 100% Food Safe.

Is PETG toxic to print?

In the 3D printing world, PETG is typically used in models that need good shock resistance or some flexibility, like snap-to-fit components. It's also a go-to material for food-related prints, as it doesn't deteriorate with water, isn't toxic, and is FDA-approved.

Is PETG heat resistant?

The softening temperature or temperature resistance of PETG is 85 ºC, this is intermediate between the PLA and ABS.

Is PETG more expensive than acrylic?

Cost. PETG plastics are a little bit more pricy and their costs depend on the application of the material. Being more efficient and flexible, acrylic is more affordable compared to PETG plastics.

What is the difference between plexiglass and PETG?

Acrylic is much more flexible than styrene, heavier in density and less susceptible to scratches due to its rigid exterior. It also has a shiny look that results in a professional looking display. PETG is more flexible and lightweight, with an impact strength of 5-7 times that of acrylic.

Is PETG good for outdoor?

PETG and ASA are filaments for outdoor use

PETG and ASA are 3D printing materials for outdoor use and durable (hold over time). Both filaments are insensitive to changing temperatures and UV rays. They are perfect to use in extreme conditions without deforming shape or appearance.

How long does PETG last outdoors?

Several of my PETG prints for outdoors use have deteriorated over the course of about 1 year. Initially, the prints are strong and have that characteristic bit of flex that you'd expect of PETG.

How do you seal PETG?

Coating your PETG print is another great way to smooth the surface and hide deformities. Much like with PLA and ABS, epoxy resin is a popular substance for coating PETG prints. XTC-3D is a particularly popular choice of epoxy in the 3D printing community.

Does PETG filament get brittle?

Quite often, I have seen people recommend printing PETG with no fan at all - seems that this is not always a good idea, my guess is that the material somehow became brittle by being heated for quite a long time and not cooling fast enough (probably crystallization, but I'm not a materials scientist).

Is PETG more brittle than PLA?

PETG has been on the uprise since a couple of years and is praised for having the ease of printing of PLA but being less brittle and thermally more resistant.

Does PETG need raft?

For printing PETG, a brim usually works best, as long as you're using a thin layer of glue as well. That's because a raft means a larger surface area is connected to the bed, making the problem worse, and a skirt does nothing to provide adhesion or an easier part-removal process.
