On this page, will find a clear instruction set on how to properly 3D-Print PLA filament with the right settings. If you have more questions, feel free to take a look at our page ‘’3D-Print support’’
To properly 3D-Print with PLA filament, a nozzle temperature between 200 – 220 oC is required. To start, choosing a temperature of 210 oC would be recommended. When the nozzle temperature is too low, the PLA filament wont liquefy properly and will cause under extrusion. Read: How to prevent under-extrusion during 3D-printing.
PLA filament can be 3D-Printed at quite a high speed. Speeds above 70 mm/s are possible but will require an increase in nozzle temperature to keep PLA hot enough to remain liquid. Printing at relatively low speeds (<40 mm/s) will give the best results, especially if your print has a lot of details.
PLA filament does not suffer much from warping during 3D-Printing. We recommend using your cooling fan on a high setting during 3D-Printing. A lot of cooling during printing gives the best results because it prevents sagging and messy melts. In this article, the importance of cooling during 3D-printing is carefully explained with some different cooled samples.
3D-Printing with PLA filament does not require a heated bed. PLA has the ideal property that it does not warp a lot when printing relatively small objects. Only when printing large surfaces, a heated bed at 60 – 70 oC will give you better results. Still experiencing warping? Take a look how to prevent warping.
If you do require a heated bed when printing with PLA filament. Make sure you apply some adhesive to the heated bed to make sure the 3D-Print will stick properly to the bed. Effective adhesives that are well suited for this application are products that use Kapton. Kapton Spray
A with PLA 3D-Printed object is not polish-able like ABS because PLA does not dissolve in a simple chemical like acetone. PLA is however still a plastic, so sanding with fine grid sandpaper and then applying lacquer might give you the satisfactory finish you desire.
