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.

Makesurethatthedevicehasastablefootingandplaceitonastableunderground.Personsmaybe
injuredifthe3Dprinterdrops.
EnsurethatthepowerandUSBcablesareneitherpinchednordamagedbysharpedges.
Alwaysplacecablessothatnoonecantripoverthemorbecaughtinthem.Thereisadangerofinjury.
• Placethe3Dprinteronadry,at,non-vibration-sensitiveandstablesurface.
Thereareanti-slipfeetonthebottomofthedevice.Ifnecessary,placeaprotectivematunderneaththedevicein
ordertoprotectthesurfaceoftheworktop.
b) Installation and connection
The mains outlet must be located near to the device and be easily accessible, so that in case of an
error, the device can be quickly separated from the mains voltage.
Be careful when handling power cable and mains connections. Mains voltage may cause potentially
fatal electrical shock.
Before plugging in the mains plug, ensure that the device voltage indicated at the 3D printer
corresponds to the available mains voltage. Do not connect the device if the indication does not
correspond to the available mains voltage. Incorrect supply voltage may lead to irreparable damage
to the device and danger to the user.

13. General notes on 3D printing
Duringprinting,nevercutoffthepowersupply,unplugtheUSBcableorremovetheSDcard.
• Theprintqualityof3Dprintersdependsonmanyfactors.Themostimportantonesare:
-print speed
- layerthickness
-build bed calibration
-temperature
- ow
- lamentmaterial
-3D model structure
• Itisnotalwayspossibletoachieveasatisfactoryprintresultattherstattempt.Adjustmentsandnetuningare
necessarytoimproveprintquality.
• Everymaterialrequiresdifferentprintsettings.
• Avoidoverhangsgreaterthan45°.Ifnecessary,usethesupportstructureoptionin“Cura“andremovesupports
afterprinting.
a) Nozzle temperature
• Thebestnozzletemperaturedependsonthelamentmaterialaswellastheprinterlayerthickness.Theprinting
temperatureofthelamentvariesdependingonlamentmaterialandlamentmanufacturer.Alwayscheckthe
specicationofthelamentbeforeprinting.ForbestresultsitisrecommendedtousegenuineRenkforcelament.
• Performthersttestprintsatthedefaulttemperature.
• To optimize the print quality, print the same object with the same printing layer thickness but different nozzle
temperatures.Selecttemperatureseachdifferentby5°Cfromthepreviousone.Comparetheresults.
Thisway youcanndsuitable nozzletemperaturesfor different laments andprintinglayer thicknessesmore
easily.
• Ifthenozzletemperatureissettoohot,thematerialcannotcooloffquicklyenoughandwillmeltthelayerbelow
again.
• Ifthenozzletemperatureistoolow,thelamentdoesnotmeltproperlyandthelamentowisnon-homogeneous.
Forthesereasons,theindividuallayersdonotmelttogethersufciently.
b) Prevent nozzle clogging
• Donotleavethenozzleatahightemperatureforalongtimewithoutprinting.
• Keepthenozzleatleast20mmawayfromthebuildbedduringloadingoflament.
• Unloadthelamentafteruse.

20
c) 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thickertheprintedlayers,thelowertheprintqualityandtheshortertheprintduration.
Experimentwiththeaboveparameterstondsatisfyingprintresultsdependingonthematerialused.
Fortherstprintattempts,usethePLAlament.Sinceitisamaterialthatcanbemasteredeasilyasitdoes
notshrinkwhilecoolingdownandadheresverywelltothebuildbed.
