3D Printing Technologies
What is 3D Printing?
3D printing doesn’t refer to one kind of manufacturing or technological process, rather it refers to a variety of technologies that additively build or form 3D parts layer by layer from CAD data.
With a CAD file, one can go from design directly to a printed model. This is significant as it changes the way we think about manufacturing with three key advantages: shorter lead time, design freedom, and lower costs.
From the expansive range of 3D printers coming in at different price points, it’s a matter of knowing which 3D Printing technology is ideal for your application in Singapore, and when to use one over the other.

PLASTIC 3D PRINTING TECHNOLOGIES
Extrudes heated thermoplastic through a nozzle layer by layer to form parts. Paired with a patented heated chamber, engineering-grade thermoplastics enable accurate, repeatable, and robust parts for functional prototyping and production.
Jets out fine print head nozzles to deposit droplets of photocurable material in layers as fine as 16 microns to form detailed 3D models. Material is simultaneously cured as it is deposited via UV light. Incorporate multiple materials, from flexible to rigid, and full color.
Uses a precise UV laser to cure liquid plastic layer by layer. After curing, the build platform retracts into a bath of liquid as a recoater blade evenly distributes the plastic across each new layer. Ideal for prototyping, master patterns, and large concept models.
METAL 3D PRINTING TECHNOLOGIES
By utilizing a laser and aiming it at a bed of metallic powder, it transforms the powder into a solid part. Parts are built up additively layer by layer to form strong, durable metal products that work well both as functional prototypes or end-use production parts.
Ultra-fine layers of solid nanoparticle inks are simultaneously jetted from sealed cartridges onto a build tray. Liquid “jacket” around the nanoparticles evaporate as it’s sintered at high temperatures, enabling dense ultrafine layers to bond.
CERAMIC 3D PRINTING TECHNOLOGIES
Ceramic components are produced using a laser to polymerize a paste composed of photosensitive resin and ceramic layer by layer. The parts are then subjected to heat treatment for debinding followed by sintering to eliminate the resin and support, and densify the ceramic.
