Printing Technologies
Level 1 : 3D Printing relates to FDM, MSLA & SLS Printing only.
Fused Deposition Modelling (FDM) - Thermoplastic Printing | Masked Stereolithography (MSLA) - Resin Printing | Selective Laser Sintering (SLS) - Nylon Printing |
FDM often referred to as Fused Filament Fabrication (FFF) is a method of 3D Printing where thermoplastic filaments (typically ABS, PLA or HIPS) are heated and extruded. At dFab PLA is used across all our FDM printers. | MSLA printing is a modified form of SLA printing whereby photopolymer resin is selectively exposed to ultraviolet light. Prints build up layer by layer with exposure to UV light, masked by an LCD screen.Once printed, dFab will wash, de-support and UV-cure all MSLA prints. | Selective Laser Sintering (SLS) is a method of additive manufacturing where nylon powder is selectively fused together using a high powered laser. As the print builds, layer by layer, the unbound powder acts as a supporting structure, eliminating the need for additional printed supports & helpers. Once printed, dFab will remove all excess uncured powder from SLS prints and bead blast prints for a consistent finish. |
