Affordable 3D Printing
3D printers are too expensive? That´s history, nowadays they are affordable for home use.
Our courses include a purchase advice to get you started with 3D printing at an affordable price (printer for less than $ 500).
ABS: plastic (acrylonitrile-butadiene-styrene), that is relatively robust in mechanical terms. Can be used as a 3D-printing filament (FDM). More difficult to print than e.g. PLA.
ABL: Automatic Bed Leveling. Automatic compensation of height deviations between printing bed & printing nozzle by capacitive or inductive sensor technology and corresponding software. Aim: Constant distance between printing bed & nozzle in order to obtain the most uniform layers possible.
Additive process: 3D printing can be assigned to this general term. In additive processes, material is deposited layer by layer to create an object. Additive processes are therefore the opposite of ablative (e.g. cutting: turning, milling, ...) manufacturing processes.
BuildTak: Plastic films or plates that improves the adhesion between printed object and printing bed. Manufacturer website: https://www.buildtak.eu
Brim: Single-layer auxiliary element to increase printing bed adhesion and prevent printing errors such as warping. Change settings in the slicing program.
Bowden Extruder: Filament feed by an externally mounted stepper motor (e.g. on the 3D printer's frame). The filament is fed through a piece of hose (e.g. made of PTFE) to the hot end.
CAD: Computer Aided Design. Engineering and design software to create your own 3D models. These models can be exported in the ".stl" format and then edited in the slicing software.
CURA: Slicing software of the 3D printer manufacturer Ultimaker. Free, open source software and easy to use.
Dual Extruder: 3D printer with two nozzles. By using a double nozzled print head, two different kinds of filaments (different material, colours, ...) can be used in one printing job. No material change is necessary during the printing process.
Extruder: Extruder: In the area of the Cold End the filament is fed to the printing head and in the area of the Hot-End it is melted.
FDM: Fused Deposition Modeling. 3D printing technology in which the 3D printer builds up the print object layer by layer on a printing platform. Popular for semi-professional applications and home use.
FFF: Fused Filament Fabrication. Same method as FDM.
Filament: Material for 3D printing. Mostly plastic (PLA, ABS, PETG, ...).
Feed rate: Feed velocity for printing. Depends on the melting speed of the hot end and other factors.
Gcode: Software-generated code (by slicing) that transmits the print head movements to the printer.
Heat-bed: Printing bed with heating function. The printing bed can be tempered for better adhesion and layer bonding.
Hot-end: Part of the printing head in which the filament is melted.
Layer: Layer of the object. see FDM
Layer Height: Layer thickness of a printing job. A lower layer height leads to a higher printing resolution or quality of the printed parts. Printing time increases with higher layer thickness.
Leveling: see printing bed leveling
Makerspace: A workshop-like location for tinkerers and inventors. 3D printers and 3D scanners are also available for use.
Marlin: Open source firmware for 3D printers.
Nozzle: Extrudes the molten printing material (filament). Nozzle diameter determines -besides other parameters - the possible layer thickness. Usual diameters: 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.8 mm, 1.0 mm
Printing bed: Surface on which the print object is built up layer by layer. Usually equipped with a heating element in order to achieve a better adhesion of the printing job. Should be as plane as possible.
Printing time: Duration of the printing process. Can be displayed in the slicing software.
Printing speed: Moving velocity of the print-head during the printing process. Normally different rates for creating walls, filling and support material can be set in the slicing program.
Printing bed levelling: Manual adjustment process for FDM 3D printers to achieve a defined distance as uniform as possible between nozzle and printing bed. Important process to achieve good adhesion and high quality prints. Levelling is done automatically by printers equipped with ABL.
PLA: polylactide acid. Biocompatible plastic and highly printable material. Recommended for beginners as a printing material. PLA+ is available as a further development (better mechanical properties).
PETG: Polyethylene terephthalate. Another plastic material for 3D printing. Especially recommended for weatherproof objects. Easier to print than ABS and mechanically stronger than PLA.
Rapid Prototyping: fast and cost-effective production of a prototype. 3D printing ideal for this. Moulding is not necessary anymore.
RepRap: self-reproducing 3D printer. All plastic parts for creating a new 3d printer are produced by the original 3D printer itself.
Skirt: Single-layer line element surrounding the actual object (often several lines), which is printed with a distance to the printed object to compensate material irregularities when printing starts (setttings can be made in the slicing software).
SLA: Stereolithography. 3D printing process in which liquid material is solidified by the process of photopolymerisation (UV light).
SLS: Selective laser sintering. 3D printing process in which a laser is used to melt material powder into a solid object layer by layer.
Stl: File format in which the geometric information of a 3D model is optimally prepared for 3D printing.
Slicer/Slicing Software: Software to slice a 3D model into individual layers, set printing settings and generate .gcode files for the printing process.
Support structure / support (material): Structure for supporting overhangs or as a build-up platform. FDM 3D printers always require a previous layer to build up on.
Thingiverse.com: Well-known community platform for uploading and downloading .stl (and .gcode) files of objects for 3D printing. Files are mostly provided free of charge under different Creative Commons licenses. Link to the platform: www.thingiverse.com
TPU: thermoplastic urethane. Flexible plastic (elastomer), usable as a filament for flexible components such as tires, toys, etc.
Warping: 3D printing error. Corners or edges of the print model detach from the printing bed and are pulled upwards.
