7. Working principle of the 3D printer
• For3Dprint,youneedale,whichcontainsthethree-dimensionaldataoftheobjecttobeprinted(acommon
formatofsuchaleis,e.g.,STL).
• Thislecanbeproducedwiththecorrespondingsoftwareorwitha3D-scanner.Therearealsomanyprintingles
alreadyonlinethatcanbedownloadedtoprintanobjectasquicklyaspossible.
• Theactualprintersoftwarehasthetasktorendertheabovethree-dimensionalleintoalethattheprintercan
print.Thisisaleinwhichtheindividualprintlayers,theprinttemperaturesfornozzleetc.arespecied.Thele
hastheextension“.gcode”.
• ThisGCODEprintingleissenttothe3DprintereitherviatheUSBinterfacebythecomputer,orsavedonSDcard,
insertedintoSDcardslotofthe3Dprinterforstandaloneoperation.
• The3Dprintercreatesthe objectlayerbylayer(Fusedlamentfabrication procedure),thelamentmaterialis
transportedfromthelamentspooltothenozzle.
• Intheextruder,thelamentmaterialismeltedandthenappliedtothebuildbedviaanenozzlelayerbylayer.
• ThebuildbedmovesintheZ(upwards/downwards)direction,theextrudermovesintheX(left/right)andY(forwards/
backwards)directions.Thus,allprerequisitestoproduceathreedimensionalobjectbyhorizontalapplicationofthe
present layers are created.
A 3D printer is a highly complex device in which many parameters must be set depending on the
printer, printed object and lament material used.
Additionally, the adhesion of the printed object on the build bed is inuenced by printing
temperature, lament material, build bed calibration, shape / size of the printed object and surface
properties of the build bed.
Ambience inuences such as drafts, grease on the build bed, etc. also play a role in the quality and
adhesion of the printed object.
For the above reasons, it is not possible to reach high-quality print results at once and without
previous experiments.
Change the adjustable parameters in small steps for the best printing results for your application.
The printing examples enclosed on the SD card provide references, but must be rened for perfect
results depending on the above parameters.
