The Differences Between a 3D Resin Printer and a Filament 3D Printer
It is important to differentiate between a 3D resin printer and a filament 3D printer especially for Professional use.
Filament 3D Printers
Filament 3D printing is also referred to as fused deposition modeling technology (FDM or FFF). In filament 3D printing, a solid polymer filament goes through an extruder assembly. After that, a motor drives it through a thermal core. It is then heated up to the point where it melts prior to being extruded onto a build plate with the help of a nozzle. The molten material is then deposited layer.
Resin 3D Printers
Resin 3D printers use liquid resin material which cures when it is subjected to UV light. It’s use depends on factors including surface quality, part throughput, proprietary technologies and more. Resin 3D printers have good surface finish quality, accuracy and precision and fast printing. There are in total three generations of 3D printers: SLA, DLP, and mSLA.
Stereolithography (SLA) 3D Printing
SLA is the first 3D printing technology invented in 1986 A liquid resin material is held in a vat which is exposed to a laser source reflected onto the resin using a set of mirrors. The polymer resin cures, the laser traces the entire cross-section of the geometry to complete one layer. Then, the process repeats itself until the part is completely printed.
Digital Light Processing (DLP) 3D Printing
Carbon DLS™ (Digital Light Synthesis) technology
A digital light projector generates a series of UV images through an oxygen-permeable. A
small amount of oxygen passes through, which brings about a dead zone. The process leads to
high quality surface finish and part production in fast speeds.
Masked Stereolithography (mSLA)
LSPc technology is the patented technology of Nexa3D and a variant of mSLA resin 3D
printer. 3D image slices are projected onto the vat where photopolymerization takes place layer by layer. It also ensures high performance. The LSPc membrane creates a no-stick zone between the printed part and the vat, which makes this. technology ultra-fast.
