6.WorkingPrincipleofthe3DPrinter
For3Dprint,rstaleisneededthatcontainsthethree-dimensionaldataoftheobjecttobeprinted(acommonformatofsuchaleis,e.g.,
a.stl-le).
Thislecanbeproducedwiththecorrespondingsoftwareorwitha3D-scanner.Therearealsomanyprintinglesonlinethatcanbedown-
loaded 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theprintingheadandheatingbed(preassembleddeviceonly),etc.arespecied.Thelehas
the extension ".gcode".
ThisG-CODEprintingleissenttothe3DprintereitherviatheUSBinterfacebythecomputer,oranSDcardwiththeprintingleisputinto
the card reader and the 3D printer is used in standalone operation.
The3DprinterthenprintstheprintlelayerforlayeraccordingtotheFFF(FusedFilamentFabrication)/FDM(FusedDepositionModelling)
procedure.
Attheactualprint,thelamentmaterialistransportedfromthelamentrolltotheprinthead(extruder).
Intheextruder,thelamentmaterialismeltedandthenappliedtotheprintingplateviaaneextrudernozzlelayerbylayer.
TheextrudermovesintheX-andY-directions,theprintingplatemovesintheZ-direction.Thus,allprerequisitestoproduceathree-dimensional
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printingplateisinuencedbylamentmaterial,shapeoftheprinted
objectandsurfacepropertiesoftheprintingplate.
 Ambienceinuencessuchasdrafts,greaseontheprintingplate,etc.alsoplayaroleinthequalityandadhesionofthe
printedobject.
 Fortheabovereasons,itisnotpossibletoachievehigh-qualityprintresultsatonceandwithoutpreviousexperiments.
 Changetheadjustableparametersinsmallstepstoachieve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.
