Stereolithography (SLA) is a 3D printing process that utilizes a computer-controlled laser to create detailed models and prototypes from liquid resin. This method is favored for its rapid production capabilities, high accuracy, and excellent surface finishes, making it ideal for concept validation and ergonomic testing. Common materials used in SLA include polypropylene, ABS, and polycarbonate, each offering unique properties for different applications.

1) What is Stereolithography
Stereolithography is a 3D Printing process which uses a
computer-controlled moving laser beam, pre-programmed
using CAM/CAD software.
Stereolithography (SL) is an industrial 3D printing process
used to create concept models, cosmetic - rapid prototypes,
and complex parts with intricate geometries in as fast as 1
day. Stereolithography parts can be produced in a wide
selection of materials, extremely high feature resolutions, and
quality surface finishes are possible with SL.

2) How Does Stereolithography Work?
The SL machine begins the 3D printing
process by drawing the layers of the
support structures, followed by the
part itself, with an ultraviolet laser
aimed onto the surface of a liquid
thermoset resin.
After a layer is imaged on the resin
surface, the build platform shifts down
and a recoating bar moves across the
platform to apply the next layer of resin.
The process is repeated layer by layer
until the build is complete.

3) Why Choose Stereolithography
for your 3D Printing Projects?
SL is an excellent choice for rapid
prototyping and project designs that
require the production of very
accurate and finely detailed parts. It’s
ideal for producing show-and-tell
parts to enable validation of concept
ideas and ergonomic testing.

4) Benefits of Stereolithography
Competitively priced
Excellent surface finish
Easily duplicates complex geometries
One of the best surface finishes for
an additive process

5) What is Stereolithography Used for?
Stereolithography is good for
producing accurate prototypes and
models.
Stereolithography is used for
prototyping in order to assess design
and for part validation. This is due to
accuracy and its ability to produce
irregular shapes.

6) What are the material
options for Stereolithography?
Polypropylene
ABS
Polycarbonate

8. https://innovae3d.com
Polypropylene
A flexible, durable resin that mimics a
stiff polypropylene. It can withstand
harsh mechanical treatment and is
great for fine details—sharp corners,
thin walls, small holes, etc.

9. https://innovae3d.com
ABS
Variations of ABS mimics
include a clear, low-viscosity
resin that can be finished
clear; an opaque black
plastic that blocks nearly all
visible light, even in thin
sections; a clear, colourless,
water-resistant plastic good
for lenses and flow-
visualisation models; and a
micro-resolution resin that
enables production of parts
with extremely fine features
and tight tolerances.

Polycarbonate
A ceramic-filled PC material that
provides strength, stiffness, and
temperature resistance, but can
be brittle.
