Powerful, Affordable 3D Printers for Professionals
Formlabs is establishing the industry benchmark for professional 3D printing for businesses around the globe with accessible, reliable 3D printers for the desktop and the benchtop. Scale your prototyping and production with high-resolution parts at a fraction of a cost and footprint of industrial 3D printers.
What is 3D Printing?
3D printing or additive manufacturing (AM) technologies create three-dimensional parts from computer-aided design (CAD) models by successively adding material layer by layer until physical part is created.
While 3D printing technologies have been around since the 1980s, recent advances in machinery, materials, and software have made 3D printing accessible to a wider range of businesses, enabling more and more companies to use tools previously limited to a few high-tech industries.
Today, professional, low-cost desktop and benchtop 3D printers accelerate innovation and support businesses in various industries including engineering, manufacturing, dentistry, healthcare, education, entertainment, jewelry, and audiology.
How Does 3D Printing Work?
All 3D printing processes start with a CAD model that is sent to software to prepare the design. Depending on the technology, the 3D printer might produce the part layer by layer by solidifying resin or sintering powder. The parts are then removed from the printer and post-processed for the specific application.
The Benefits of 3D Printing
With traditional manufacturing processes, it can take weeks or months to receive a part. 3D printing turns CAD models into physical parts within a few hours, producing parts and assemblies from one-off concept models to functional prototypes and even small production runs for testing. This allows designers and engineers to develop ideas faster, and helps companies to bring products more quickly to the market.
With 3D printing, there’s no need for the costly tooling and setup associated with injection molding or machining; the same equipment can be used from prototyping to production to create parts with different geometries. As 3D printing becomes increasingly capable of producing functional end-use parts, it can complement or replace traditional manufacturing methods for a growing range of applications in low- to mid-volumes.
3D printing can create complex shapes and parts, such as overhangs, microchannels, and organic shapes, that would be costly or even impossible to produce with traditional manufacturing methods. This provides the opportunity to consolidate assemblies into less individual parts to reduce weight, alleviate weak joints, and cut down on assembly time, unleashing new possibilities for design and engineering.
Product development is an iterative process that requires multiple rounds of testing, evaluation, and refinement. Finding and fixing design flaws early can help companies avoid costly revisions and tooling changes down the road. With 3D printing, engineers can thoroughly test prototypes that look and perform like final products, reducing the risks of usability and manufacturability issues before moving into production.
From shoes to clothes and bicycles, we’re surrounded by products made in limited, uniform sizes as businesses strive to standardize products to make them economical to manufacture. With 3D printing, only the digital design needs to be changed to tailor each product to the customer without additional tooling costs. This transformation first started to gain a foothold in industries where custom fit is essential, such medicine and dentistry, but as 3D printing becomes more affordable, it’s increasingly being used to mass customize consumer products.
Applications and Uses of 3D Printing
Rapid prototyping with 3D printing empowers engineers and product designers to turn ideas into realistic proofs of concept, advance these concepts to high-fidelity prototypes that look and work like final products, and guide products through a series of validation stages toward mass production.
3D Printing Technologies
Formlabs offers two professional 3D printing technologies, stereolithography and selective laser sintering, bringing these powerful and accessible industrial fabrication tools into the creative hands of professionals around the world.
How Stereolithography Works
Stereolithography (SLA) 3D printing uses a laser to cure liquid photopolymer resin into solid isotropic parts.
With the common process, inverted SLA, a build platform is lowered into a tank of resin, leaving only a thin layer of liquid in between the platform and the bottom of the tank. Galvanometers direct the laser through a transparent window at the bottom of the resin tank, drawing a cross-section of the 3D model and selectively hardening the material. The print is built in consecutive layers, each less than a hundred microns thick. Support structures keep overhangs anchored to the platform where necessary. When a layer is complete, the part is peeled from the bottom of the tank, letting fresh resin flow beneath, and the platform is lowered once again. This process repeats until the print is complete.
Stereolithography is ideal for:
- Rapid prototyping
- Functional prototyping
- Concept modeling
- Short-run production
- Dental applications
- Jewelry prototyping and casting
Selective Laser Sintering (SLS)
How Selective Laser Sintering Works
Selective laser sintering (SLS) 3D printers use a high-power laser to sinter small particles of polymer powder into a solid structure.
The powder is dispersed in a thin layer on top of a platform inside of the build chamber and the printer preheats the powder to a temperature just below the melting point of the raw material. The laser scans a cross-section of the 3D model, fusing the particles together mechanically to create a solid part. The unfused powder supports the part during printing and eliminates the need for dedicated support structures. The platform lowers by one layer into the build chamber, typically between 50 to 200 microns, and a recoater applies a new layer of powder on top. The laser then scans the next cross-section of the build and this process repeats for each layer until parts are complete.
Selective laser sintering is ideal for:
- Functional prototyping
- End-use parts
- Short-run, bridge, or custom manufacturing
