18. General Notes on 3D Printing
The print quality of 3D printers depends on a great many factors.
Itisnotalwayspossibletoachieveasatisfactoryprintresultattherstattempt.
Extruder temperature
Thebestextrudertemperaturedependsonthelamentmaterialandtheprinterlayerthickness.Themanufacturerinformationfortheprinting
temperature can vary very strongly here.
Performthersttestprintsatatemperatureinthemiddlerangeofthemanufacturer'sinformation.
Tooptimisetheprintquality,printthesameobjectwiththesameprintinglayerthicknessanddifferentextrudertemperaturesin5°Cstepsand
then compare the results.
Thiswayyoucanapproachthebestextrudertemperaturefordifferentlamentsandprintinglayerthicknessesmosteasily.
If the extruder temperature is set too hot, the material cannot cool off fast enough and will melt the layer below again.
Iftheextrudertemperatureistoolow,thelamentwillnotbecomeliquidenoughandthelamentowisnothomogeneous.Theindividualla-
mentlayersalsocannotcombinesufciently.
Heatingbedtemperature(inthepreassembleddeviceorwhenusingtheoptionalheatingplatekit)
Theoptimalheatbedtemperaturealsodependsonthelamentmaterial.Itpermitsperfectadhesionoftheprintedobjecttotheheatingplate.
PLAcanalsobeprintedwithoutaheatingbed,butatemperatureofapprox.60°Chasturnedouttobeideal.
WhenprintingPLA(particularlyatsmallobjectswithasmallfootprint),theheatingbedshouldadditionallybeappliedwithcleaningtapeora
slightly structured crepe tape to increase surface adhesion.
If the heating bed temperature is too high, the printed object may distort or the lower layers will cool off too slowly.
Iftheheatingbedtemperatureistoolow,theprintedobjectwillnotadheresufcientlyorthecornerswillcomefreeoftheheatingplatewhile
printing.
Printlayerthickness
The print layer thickness determines the height of the individual print layers and thus the resolution and quality of the printed object.
The thinner the printed layers, the better the print quality and the longer the print duration.
The thinner the printed layers, the lower the print quality and the shorter the print duration.
Experimentwiththeaboveparameterstondthebestprinterresultsforyoudependingonthematerialused.
 TherstprintattemptsshouldbedonewithPLAlament,sinceitisamaterialthatcanbemasteredrelativelyeasilyandthatis
subject to fewer problems with shrinkage, accuracy and adhesion on the heating plate.
