Delve additional into this weblog to find out about:
- The origins of stereolithography (SLA), and why it’s nonetheless thought-about such a strong type of 3D printing at this time.
- The scalability of 3D printing with superior SLA know-how and superior supplies.
- How Accura 60 possesses related properties to common supplies like molded Polycarbonate (PC).
- Why Accura Xtreme is a superb alternative for creating grasp patterns utilized in injection molding.
- When to show to supplies like Accura Xtreme 200 for robust elements.
Stereolithography (SLA) is notably the oldest type of 3D printing, per the historic days of pioneers like Chuck Hull and different engineers in search of higher methods to carry out speedy prototyping and enhance product growth. Like Selective Laser Sintering (SLS), that is nonetheless one of the revered and highly effective types of know-how which has continued to advance together with the complete additive manufacturing trade, extensively used for creating 3D fashions, grasp patterns, and purposeful elements.
For designers and engineers who perceive find out how to lean into the numerous advantages of SLA, the outcomes might be spectacular for manufacturing exact, high-quality industrial elements that require clean floor finishes and extra intricate element than others; in actual fact, that’s one motive industrial customers could use SLA as a go-to know-how over SLS—when looking for intense element and dimensional accuracy. SLA 3D printing can be used as an accompaniment to extra typical manufacturing practices like injection molding, 3D printing the molds for making a flexible vary of commercial elements.
Understanding SLA 3D Printing Know-how
Settled into the vat polymerization class—together with direct mild processing (DLP)—SLA depends on lasers and resin to construct 3D printed buildings. A strong laser solidifies, or cures, every skinny layer of liquid resin deposited onto the construct platform on the prime of the resin tank. Because the platform strikes up and out of the resin tank, the half is 3D printed in a repetitive course of constructing the half layer by layer.
A high-powered laser beam traces or attracts the design of the half in every layer, which then solidifies, or cures, because of the warmth of the laser. The common layer top in SLA 3D printing is about 100 microns, with a minimal of 25 microns. The potential for accuracy and precision are arduous to prime—particularly when enhanced by superior supplies from Shapeways. Robust adhesion is one other enormous profit stemming from SLA, creating a wonderful basis from the beginning in every print, and eliminating worries over structural integrity later.
SLA 3D printing can also be interesting to Shapeways clients as a result of it’s so scalable, providing the flexibility to fabricate small, intricate, however correct elements—in addition to bigger buildings with a lot better construct volumes and the identical incredible floor high quality.
SLA 3D Printing Supplies
As developments proceed towards extremely industrial, vital purposes, Shapeways clients flip to superior SLA supplies like the next: This clear plastic produces inflexible and sturdy elements with related properties to molded Polycarbonate (PC). It has the flexibility for fantastic particulars making it apt for robust, purposeful prototypes, lighting parts, medical devices and fluid circulate and visualization fashions.
A cloth with related bodily properties to polypropylene and ABS, Accura® Xtreme is an ultra-tough gray plastic with excellent sturdiness, accuracy, moisture and thermal resistance and the flexibility for excellent element. It’s ultimate for snap match assemblies, enclosures for client and digital merchandise, grasp patterns for vacuum casting, and basic goal prototyping.
Accura® Xtreme™ 200
This white plastic is the hardest SLA materials obtainable and may exchange CNC-machined polypropylene and ABS articles. It’s good for tasks that should stand up to excessive, harsh situations making it ultimate for difficult purposeful assemblies. It may be utilized to related tasks as Accura Xtreme as effectively tasks that demand the best sturdiness like automotive elements, drill/faucet purposes, assemblies with self-tapping screws, enclosures for client digital parts, basic goal prototyping, and grasp silicone molding.
Purposes Appropriate for SLA Supplies
All three of those SLA supplies produce inflexible, sturdy elements that resist breakage and are sturdy sufficient to create purposeful elements in addition to present glorious element and accuracy. SLA Plastics are printed on giant format 3D printers which is nice for creating extra sizable elements for visible prototypes, short-run manufacturing, and mass customization together with particular purposes comparable to:
- Grasp patterns for vacuum casting
- Shell funding casting patterns for steel casting
- Advanced assemblies
- Wind tunnel fashions
- Fast manufacturing of circulate take a look at rigs
- Mass customization manufacturing (orthodontic, dental)
- Customized meeting jigs and fixtures
These supplies have a bigger construct quantity than normal SLA know-how, which implies your tasks could have much less limitations.

Assist Constructions and Publish Processing for SLA 3D Printing
SLA 3D printing doesn’t finish with the 3D printer. Assist buildings are all the time required for SLA 3D printing, however with correct design and half orientation, they are often diminished as a lot as potential. These kinds of buildings are a lot thinner in SLA 3D printing, and though coping with them in post-processing could be a slight problem, their presence permits for better latitude in creating advanced geometries and increasing innovation.
Helps help in stabilizing advanced geometries throughout printing, together with defending fashions which will embrace overhangs extending outward from the design. Helps hold fashions 3D printed with SLA in place on the print mattress, offset excessive temperatures in some instances, forestall warping, curling, and sagging, and general, cut back the potential for misshapen or collapsed prints.
Finally, put up processing presents the chance to complete elements with spectacular high quality. Earlier than eradicating helps, every SLA half is washed clear of additional materials, sometimes using a shower of a number of solvents to take away undesirable resin. Components should dry utterly, after which might be post-cured with UV mild and better temperatures to make sure the best high quality in end and mechanical properties too. Helps are eliminated with warning, nevertheless, fashions should bear marks left over from removing. They are often simply sanded away on the finish of the post-processing part although.
