3D printing

What is 3D printing?

3D printing, also known as additive manufacturing, is a process by which physical objects are created by depositing materials in layers based on a digital model. All 3D printing processes require software, hardware, and materials to work together.

3D printing technology can be used to create everything from prototypes and simple parts to highly technical final products such as airplane partseco-friendly buildingslife-saving medical implants, and even artificial organs using layers of human cells.

Common methods of 3D printing

Advances are rapidly being made to make 3D printing technology reliable for mass manufacturing production-grade parts, and scientists and inventors are finding new ways to apply 3D printing technology every day.

Fused filament fabrication (FFF)
Also known as fused deposition modeling (FDM). This method of 3D printing heats and extrudes plastic materials. It's common in both consumer and professional 3D printers. Example 3D printers include MakerBot Replicator and Ultimaker 2.

Stereolithography (SLA)
This method of 3D printing uses UV light to cure or harden resins, layer by layer. Example 3D printers include Autodesk Ember and Formlabs Form 1.

Selective laser sintering (SLS)
Common in industrial manufacturing, this method of 3D printing uses lasers to fuse powdered materials together, layer by layer. Example SLS 3D printer manufacturers include EOS and 3D Systems.

An open platform for 3D printing

Spark is an open platform of 3D printing technologies and services that connects hardware, software, and materials. Today, the 3D printing workflow from design to manufacturing is often fragmented. This can make 3D printing complicated and unreliable for many end users.

With APIs, SDKs, sample applications, and services from Spark, we’re providing companies with tools to help bridge these gaps, so 3D printing can work better for everyone.
