Read also: 3D Printing for Digital Dentistry & Clear Aligner Manufacturing Material Extrusionįused Deposition Modeling (FDM), as known as fused filament fabrication (FFF), is one of the most popular 3D printing methods for industrial uses. What can be distilled from the recent news is that 3D printing resin development has reached a new level: companies are extremely focused on advanced applications, particularly in the medical, dental and engineering fields. Over the last 12 months, we’ve heard multiple announcements about new 3D printing resins from the likes of Formlabs, Henkel, Zortrax, DSM, and many more. The choice of materials for SLA is constantly expanding. SLA photopolymers come in a variety of colour options as well as several speciality materials (castable, durable, high-temperature, medical-grade).
Also, since SLA materials are sensitive to UV light, their mechanical properties can change due to overexposure to sunlight, thus making them unsuitable for outdoor use. While SLA parts offer a great surface finish, they tend to be less durable than parts produced with other additive technologies. These are selectively cured by a UV laser layer by layer, causing the resin to solidify. SLA relies on liquid photocurable resins.
Due to its accuracy and high resolution, SLA parts are mostly used for form and fit concept models or as master patterns for moulding applications. SLA is an ideal technology for producing great looking parts with an excellent surface finish.
The emergence of Stereolithography (SLA) in the 1980s marked the beginning of the 3D printing era. Polymer 3D printing was predicted to have generated $11.7 billion in revenues in 2020, a figure that includes sales of hardware, materials and 3D-printed parts combined.īelow, we’re taking a look at the key technologies driving this growth. They lead on all fronts: shipment revenues, the installed base, and the number of developments happening in this space. Polymer 3D printers dominate the 3D printing hardware arena.
