SLA 3D printing is becoming
increasingly popular in a number of industries for producing products, parts,
and prototypes with high-accuracy and smooth surface finish. First invented in
the 1980’s, it is now one of the most accurate forms of 3D printing process
that solidifies or print a liquid polymer resin in a physical 3D object layer
by layer using an ultraviolet (UV) laser beam. With the accuracy and
advancement of 3D printing technology, more and more industries are approaching
to it for creating models, prototypes, patterns, and production parts.
SLA or Stereolithography is a form of
3D printing technology that is used for advanced manufacturing based on 3D CAD,
computer-controlled layers scanning, rapid layer separating, and accumulating
principles. A standard SLA 3D printer composes the four primary sections:
· A tank filled with the liquid photopolymer resin
· A perforated platform immersed in a tank
· A high-powered, ultraviolet laser
· A computer interface to manage the printing process
The SLA 3D
printing workflow Includes:
·
Designing
process using 3D CAD software to design your model and then export it in a 3D
printable file format.
· Printing process where build platform lowers into the tank filled with liquid photopolymer resin to print a 3D model of the object as per the design. The polymer resin hardens into a solid layer by layer via repeated process until the object completes.
· Post-processing the printed SLA parts using various pos- processing methods including post-curing, sanding, spray coating, and polishing for the clean finish.
There are many reasons to choose SLA 3D printing for manufacturing or producing prototypes or products. Its fine features, high-accuracy, precision, smooth surface finish, material versatility, and water tightness makes it popular among manufacturers, engineers, and designers.
Benefits of
SLA 3D Printing:
·
SLA
is one of the most precise and accurate 3D printing technology available in the
market.
· Able to create intricate and highly detailed designs; also suitable for complex geometrical shapes.
· Layers are chemically bonded with each other that offer high mechanical strength; also provides the tightest dimensional tolerances.
· Fine features and high smooth surface finish;
· Material versatility; SLA material comes in different forms of liquid polymer resin including standard resin, clear resin, castable resin, high-temperature resistant resin, dental resin, and many more for different industrial manufacturing;
· Easy & cost-effective than other 3D printing technologies;
Applications
of SLA 3D Printing:
SLA 3D printing technology is used in
businesses across a wide range of industries including engineering, product
design, dental, manufacturing, jewellery, healthcare, audiology, and more. Some
of the most common daily life products that can be produced using SLA 3D
printing methods include toys, house appliances, automotive parts, medical
devices, and many more.
If you are into any of the above
industries and want to produce or manufacture your products using advanced SLA
3D printing technology, you can contact professional 3D printing services as
