Guide to Stereolithography (SLA) 3D Printing: How Resin 3D Printers Work
HTML-код
- Опубликовано: 27 мар 2017
- Stereolithography (SLA) 3D printing is the most common resin 3D printing process that has become vastly popular for its ability to produce high-accuracy, isotropic, and watertight prototypes and end-use parts in a range of advanced materials with fine features and smooth surface finish.

Stereolithography was the world’s first 3D printing technology, invented in the 1980s, and is still one of the most popular technologies for professionals. Stereolithography belongs to a family of additive manufacturing technologies known as vat photopolymerization, commonly known as resin 3D printing. It uses a UV laser to cure liquid resin into hardened plastic.
SLA 3D printing has the highest resolution and accuracy, the clearest details, and the smoothest surface finish of all plastic 3D printing technologies, but the main benefit of SLA lies in its versatility. Material manufacturers have created innovative SLA photopolymer resin formulations with a wide range of optical, mechanical, and thermal properties to match those of standard, engineering, and industrial thermoplastics.
SLA 3D printers use light-reactive thermoset materials called resin. When SLA resins are exposed to certain wavelengths of light, short molecular chains join together, polymerizing monomers and oligomers into solidified rigid or flexible geometries.
Resin is either poured into a tank by a user, or dispensed automatically from a cartridge, depending on the concrete stereolithography machine.
SLA 3D printing starts by lowering a build platform into the resin and leaving only a thin layer of liquid in between the platform and the bottom of the tank. Afterwards, galvanometers direct the UV laser at the bottom of the resin tank, drawing a cross section of the 3D model and selectively hardening the material. After a layer is finished, the part is peeled from the bottom of the resin tank, letting fresh resin flow beneath, and the platform is lowered once again.
Desktop stereolithography high resolution 3D printing is an affordable option for your workspace. Whether for an engineer, product designer, sculptor, jeweler, or dentist, with the right material there is an SLA application for your profession. SLA 3D printing applications include a variety of areas, such as engineering and product design, manufacturing, dental, healthcare, education, entertainment, jewelry, or audiology.

This process looks so cool! like a T-900 emerging from a puddle.
Cool I was wondering how they worked now. I trained in California and ran one in Florida it was like a two door refrigerator size with the lynic PC station on the side. It was in the late 80's to the early 90's. I still Have a few parts I built on it and of course the ship in the bottle.
wow
Anyone know how much resin does the it hold? The one I ran was over a gallon and was impractical to change.
Man this printer is good, too bad it takes ages to save enough money for this as a student :D
trop styler wtf mais une question on ^peut faire un god avec ? juste pour voir si ca fait du bien ?
Question. what are the benefits of SLA?
Have been wondering for a while about this but what's the material that makes the cover? It's supposed to block the light from the outside but you can also see what's printing.
A bit late but it is Photochromic (ie. lens): made of glass, polycarbonate and others.
It filters out a specific range of light so the resin doesnt cure
What are the cheapest models avail. for consumer use?
Little late, but Anycubic Photon/Photon S and EPAX X1 are pretty cheap. Great print quality and easy to use.
Does the final part melt when exposed to sun light or room temperature?
No it doesnt but parts can get brittle due to overcuring
Price mechin
