What can dissolve PETG?
Dichloromethane, methyl ethyl ketone (MEK), toluene, and cyclohexanone have all been proven to dissolve PETG as well, yet they are all extremely dangerous and should only be used by experts.
Does ethyl acetate dissolve PETG?
This means using some chemical vapor to start melting and dissolving the outer surface of a 3D print to smooth all the layer lines together. A similar but much safer chemical that has been shown to smooth PETG is ethyl acetate, and as a matter of fact “non-acetone” nail polish remover is most often ethyl acetate.
Will gasoline dissolve PETG?
RE: PETG petrol resistant PET and Gasoline just ignore each other. Containers printed in PETG should not be used for Gasoline because 3D prints (filament) are notorious leakers – you don’t want to leak gasoline in unexpected places.
What does acetone do to 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 smooth PETG with acetone?
For other filaments (ABS*, for example), it is often advised to smooth the surface with acetone (ABS Smoothing Guide). This does not work with PETG, because the solvent cannot harm the PETG. And this also applies to the other solvents that are commonly used in 3D printing to smooth surfaces.
Is PETG self extinguishing?
A; Yes, PETG is Class 1 BS476 part 7, and is a self extinguishing material.
Can you heat treat 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.
Can PETG be vapor smoothed?
However, the chemical resistance of PETG also means that it cannot be smoothed by chemical means, such as the acetone vapor bath used for ABS. If you want to smooth your PETG print, you are going to have to take a back to basic approach. You can also smooth your PETG print using a heat gun.
Is PETG hydrophilic?
Because PETG is hygroscopic, you need to dry your spool before using it, which can easily be done using a PrintDry PRO to pull the moisture out of your filament.
Is PETG flame resistant?
FRJet this material is based on PETG and contains a mixture of special additives with a flame-retardant (UL94 V0 certification).
What makes PETG a good material for 3D printing?
The characteristics of PETG emphasize why many 3D printing professionals consider it as a “bridge” material between PLA and ABS. It offers a comparable level of durability, heat resistance, and chemical resistance as ABS but is just about as simple to handle as PLA.
Is it possible to finish a PETG print using a solvent?
The truth is that it’s possible to finish a PETG print using a solvent. Acetone isn’t an option because it does not dissolve PETG. If you’re looking for a solvent that can dissolve PETG, you’re left with three alternatives: toluene, cyclohexanone, and MEK (methyl ethyl ketone).
Why is it harder to dissolve PETG filament?
It’s possible that due to some changes in PETG filament structure that makes it easier to print also makes it harder to dissolve. It’s also possible, that despite finding positive results in other communities using this method and materials, there was some different variable in their process.
Why is smoothing a PETG print so difficult?
PETG is impervious to degradation by most acids, bases, and solvents. While this property is desirable in the for industrial and commercial end-users, it is also a reason for why smoothing a PETG print is challenging (as we shall see later). 3. Heat resistance
