What is DLP in 3D printing?

DLP (Digital Light Processing) is a 3D printing technology used to rapidly produce photopolymer parts. It’s very similar to SLA with one significant difference — where SLA machines use a laser that traces a layer, a DLP machine uses a projected light source to cure the entire layer at once.

How do DLP 3D printers work?

DLP 3D printers use a digital projector screen to flash an image of a layer across the entire platform, curing all points simultaneously. The light is reflected on a Digital Micromirror Device (DMD), a dynamic mask consisting of microscopic-size mirrors laid out in a matrix on a semiconductor chip.

What is 3D DLP projector?

3D DLP Projectors Models – This new model accepts 3D signals in any of the 3D signal formats required by the HDMI 1.4a standard and converts them internally into a 720p 120Hz sequentially alternating video stream for display. Thus when using this projector for 3D video, each eye sees 60 video frames per second.

What does SLS stand for 3D printing?

Selective laser sintering (SLS) 3D printing is trusted by engineers and manufacturers across different industries for its ability to produce strong, functional parts.

How does Digital Light Processing work?

Digital Light Processing makes use of micromirrors, called a Digital Micromirror Device, to reflect light and color onto a screen. These micromirrors are positioned in a semiconductor chip and are very small. Generally, a micromirror pitch may measure less than 5.4μm.

What is resin 3D printing called?

Stereolithography belongs to a family of additive manufacturing technologies known as vat photopolymerization, commonly known as resin 3D printing. These machines are all built around the same principle, using a light source—a laser or projector—to cure liquid resin into hardened plastic.

What is Multi Jet Fusion 3D printing?

Multi Jet Fusion is an industrial 3D printing process that produces functional nylon prototypes and end-use production parts in as fast as 1 day. Final parts exhibit quality surface finishes, fine feature resolution, and ‬more consistent mechanical properties when compared to processes like selective laser sintering.

What does Msla stand for 3D printing?

Masked Stereolithography (MSLA) printers and traditional Stereolithography (SLA) 3D printers use a UV resin to create a 3D object, layer by layer to cure the liquid resin into a final printed part.

What’s better PLA or ABS?

PLA and ABS are both thermoplastics. PLA is stronger and stiffer than ABS, but poor heat-resistance properties means PLA is mostly a hobbyist material. ABS is weaker and less rigid, but also tougher and lighter, making it a better plastic for prototyping applications.

Is resin printing stronger?

FDM prints are generally stronger than 3D resin prints. Specifically, the tensile strength of FDM prints ranges from 38-64MPa, while those of resins are generally lower at 23-55Mpa. Also, FDM prints have higher flexural strengths at 2.1-7.6GPa, while resins only average at 60.6MPa.
