What is a good initial layer height for 3D printing?
If you would prefer the first layer to be squished, a value of -0.05mm will be a good start. For a layer height of 0.2mm, this will give about 25% squish. Another way to think of this is that 100% of your extrusion will be forced into a space that is 75% of the layer height.
How do you keep PETG from stringing?
Another quick fix for PETG stringing is to increase travel speed. The quicker the nozzle moves between two points, the less time melting filament will have to ooze. Try increasing your printer’s travel speed in 10-mm/s increments until you find the perfect speed. Some makers even use travel speeds of up to 200 mm/s.
Is PETG as strong as ABS?
PETG is more durable than ABS, but ABS is harder, and more rigid. PETG has a lower glass transition temperature, at 80C compared with ABS’s 105C. ABS is approximately 20% less dense than PETG.6 jui. 2018
Does PETG shrink?
PETG has a shrink ratio (or shrink rate) of less than 0.004 in/in so printing large surfaces are not a problem when printing on a well-leveled surface.21 oct. 2016
Is smaller layer height stronger?
Thinner layers could be stronger because the molten material is squished out more from the nozzle and due to the low distance between nozzle the previous layer warms the material and helps with bonding.28 sept. 2019
What is a good first layer height?
A good rule of thumb is for the first layer height to be 90% lower than the other layers. This will extrude the same amount of plastic into a space 10% lower so the plastic will squish flatter against the bed. (Think about the reverse of that.14 jui. 2016
What speed should I print PETG?
between 60 and 100 mm/s
Can Ender 3 use PETG?
Because of the high melting temperature of PETG, we advise establishing your Ender 3’s bed temperature level to between 50 and also 60 ° C. The conventional Ender 3 develop surface, BuildTak, is the optimal surface area for printing PETG with the Ender 3.25 nov. 2020
Does PETG need cooling fan?
Fans & Cooling PETG will print quite nicely without fans. Unlike other materials which require fans during printing, PETG actually does better without them. … You should use fans only if you want more details in your print, or if you’re printing bridges.
Will PETG melt in a car?
PETG. PETG is similar to PLA but has a higher glass transition temperature of up to 80o C. So in most cases, PETG doesn’t melt in a car. However, UV light can affect PETG, too, so you may consider painting it.
Will PETG melt in sunlight?
PETG 3D printer filaments have a melting point of about 260°C. … In the long run, PETG can offer better results in the direct sun as it has the ability to withstand UV radiation much better as compared to other filaments such as PLA and ABS. PETG can be used for various applications and can be kept in the car as well.
Is PETG easy to sand?
Coating PETG 3D Printer Filament It sands really easily and gives your parts a glossy finish right off the bat if you don’t intend on sanding it further.11 sept. 2017
Is PETG waterproof?
PETG, a modification of PET, which is used in water bottles, is a great material for making waterproof prints. PETG is commonly considered to be waterproof and also has an excellent thermal resistance.11 mai 2021
Does PETG shrink in heat?
PETG (Polyethylene Terephthalate Glycol) is the most heat resistant shrink sleeve material, offers high scuff resistance, and provides excellent clarity. This film starts to shrink between 158° F and 176° F, and has a high shrink percentage (up to about 80%).25 jan. 2017
Does PETG go bad?
ABS filament may expire within a month of humidity exposure, while bio-plastics such as PETG and PLA may last one to two years respectively, without going bad. … Water moisture is a 3D printer filament worst enemy, but even brief exposure to air can damage an entire spool.
