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.
See how to go from design to 3D print with the Form 3 SLA 3D printer. This 5-minute video covers the basics of how to use the Form 3, from the software and materials to printing and post-processing.
3D printers create parts from three-dimensional models, the mathematical representations of any three-dimensional surface created using computer-aided design (CAD) software or developed from 3D scan data. The design is then exported as an STL or OBJ file readable by print preparation software.
3D printers include software to specify print settings and slice the digital model into layers that represent horizontal cross-sections of the part. Adjustable printing settings include orientation, support structures (if needed), layer height, and material. Once setup is complete, the software sends the instructions to the printer via a wireless or cable connection.
2. 3D Print
Some 3D printers use a laser to cure liquid resin into hardened plastic, others fuse small particles of polymer powder at high temperatures to build parts. Most 3D printers can run unattended until the print is complete, and modern systems automatically refill the material required for the parts from cartridges.
With Formlabs 3D printers, an online Dashboard allows you to remotely manage printers, materials, and teams.
Depending on the technology and the material, the printed parts may require rinsing in isopropyl alcohol (IPA) to remove any uncured resin from their surface, post-curing to stabilize mechanical properties, manual work to remove support structures, or cleaning with compressed air or a media blaster to remove excess powder. Some of these processes can be automated with accessories.
3D printed parts can be used directly or post-processed for specific applications and the required finish by machining, priming, painting, fastening or joining. Often, 3D printing also serves as an intermediate step alongside conventional manufacturing methods, such as positives for investment casting jewelry and dental appliances, or molds for custom parts.
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.
Engineers at the AMRC turned to 3D printing to rapidly produce 500 high-precision drilling caps used in drilling trials for Airbus, cutting the lead time from weeks to only three days.
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.
Pankl Racing Systems substituted machined jigs and fixtures with 3D printed parts, decreasing costs by 80-90 percent that resulted in $150,000 in savings.
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.
Gillette's Razor Maker™ gives consumers the power to create and order customized 3D printed razor handles, with the choice of 48 different designs (and counting), a variety of colors, and the option to add custom text.
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.
Nervous System launched the first-ever 3D printed ceramic jewelry line, consisting of intricate designs that would be impossible to manufacture using any other ceramic technique.
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.

Types of 3D Printers
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
