In filament form, PETG (glycol modified PET) offers some notable advantages over PLA, such as excellent layer adhesion, good impact resistance, and a low level of shrinkage. It’s affordable too: a spool of cheap PETG filament only costs about $5 more per kilogram than PLA from an ...
What I’ve found is that specifically for PETG, both too high and too low can cause adhesion issues. You need to have the absolute perfect first layer, or it won’t stick: image1920×1080 67 KB I was able to figure out the “perfect” first layer by following 90% of what the SM...
PETG can be used with enclosed and open 3D printers. The print bed should be heated to 75–90 °C. For adhesion of the first layer, the bed must be covered with a coat of glue or "printing juice" — a solvent with plastic dissolved in it. The extruder temperature is 230–250 °C...
PETG filament prints at hotter temps than PLA leading to stronger layer adhesion, thus higher quality and more sturdy printed parts. Unlike ABS, however, PETG is greatly easier to print with. Printed PETG parts are applied widely in industrial thermoplastic scenarios and have been employed desir...
PLA filaments have the advantages of incredible ease of printing Optimized printing quality, high purity with low shrinkage and superb layer bonding, meeting your demands for printing projects of functional parts with higher toughness. PLA Filament Parameter ...
One of the most basic problems in the study of heat transfer over external surfaces is the natural convection boundary layer flow over a semi-infinite flat plate [65]. The free convection problem of a non-isothermal vertical plate has been extensively studied by several authors [66,67,68,69...
After the start of the printing process, the first layer was printed. This is critical, especially with PETG-CF15. If it does not adhere perfectly to the printing surface, the product comes off and the print is lost. To ensure good adhesion throughout the entire printing process, a so-ca...
