3D PRINTING METHODS AND MATERIAL DESCRIPTION

FDM – Fused Deposition Modeling (FFF – Fused Filament Fabrication)

The most popular and affordable 3D printing method today. A FDM 3D printer works by depositing melted filament material over a build platform layer by layer until you have a completed part. This method has a variaty of materials that can be used. All materials are in a form of a filament. The printed models have slightly visible layer lines (depends on the layer height and material). Different infil percentages and patterns can be used as a compromise between strength and economy.

Featured Materials:  PLA, PETG, ABS, ASA, TPU, NYLON, PEEK, PC …

PLA: biodegradable material with good strength and low UV resistance, temp. resistant up to around 55°C

PETG: plastic material similar to PET (plastic bottles), usually a little translucent when printing thinner parts, temp. resistant up to around 70°C

TPU: flexible material (rubber like). We use by default the Sha class 95A. Get in touch with us if you’d preffer a different class

 

SLA – Stereolithography

Stereolithography is a 3D printing process which uses a computer-controlled moving laser beam, pre-programmed using CAM/CAD software. The 3D printed model is manufactured from a special UV sensitive RESIN (Liquid) which is cured (hardened) with the use of the aforemeantioned laser. Appropriate for large models that need a nice surface finish. Because of it’s hardness, non-ductility and fragility it’s not appropriate for mechanical parts.

DLP – Digital Light Processing

DLP is a 3D printing process where models are printed with a special UV sensitive RESIN (Liquid). It’s very similar to SLA with one significant difference — where SLA machines use a laser to harden the resin, a DLP machine uses a projected light source to cure the entire layer at once (usually LCD screen or projector). Appropriate for smaller models that need a nice surface finish. Because of it’s hardness, non-ductility and fragibility it’s not appropriate for mechanical parts.

SLS – Selective Laser Sintering

Selective Laser Sintering (SLS) is an additive manufacturing process that belongs to the Powder Bed Fusion family. In SLS 3D printing, a laser selectively sinters the particles of a polymer powder, fusing them together and building a part, layer by layer. The materials used in SLS are thermoplastic polymers that come in a granular form (powder). Altough the layer lines are not visible the surface finish is still a little rough. The method is appropriate for parts that need high strength.

MJF – Multi Jet Fusion

Multi Jet Fusion is an industrial 3D printing process developed by HP that produces functional nylon prototypes and end-use production parts. Final parts exhibit quality surface finishes, fine feature resolution, and more consistent mechanical properties when compared to processes like selective laser sintering. Using an inkjet array, MJF works by depositing fusing and detailing agents on a powder material, then fusing them into a solid layer.

 

Featured Materials: Powder from plastic polymers (NYLON PA-12, …)

SLM – Selective Laser Melting

Selective laser melting (SLM) is a specific 3D printing technique, which utilizes high power-density laser to fully melt and fuse powders to produce near net-shape parts with near full density. The material used for this process is usually metal powder.
