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 and is significant as it changes the way we think about manufacturing with three key advantages: shorter lead time, design freedom, and lower costs.

Creatz3D offers an expansive range of 3D printers and solutions comprising of multiple technologies, and so it’s a matter of knowing which technology is good for your application, and when to use one over the other.

PLASTIC 3D PRINTING TECHNOLOGIES

FUSED DEPOSITION MODELING (FDM)

Extrudes heated thermoplastic through a nozzle layer by layer to form parts. Paired with a patented heated chamber, strong engineering-grade thermoplastics enable the creation of accurate, repeatable, and robust parts ideal for functional prototyping and production.

POLYJET
TECHNOLOGY

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.

STEREOLITHOGRAPHY
(SLA)

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.

SELECTIVE ABSORPTION FUSION (SAF)

Designed for production-level throughput of end-use parts, SAF is an uniquely different powder bed fusion technology that uses an infrared-sensitive high absorbing fluid (HAF) to fuse particles of polymer powders together in discrete layers to build parts.

METAL 3D PRINTING TECHNOLOGIES

BOUND DEPOSITION MODELING (BMD)

A green part is shaped by extruding bound metal rods, metal powder held together by polymer binders, layer by layer. Printed parts are heated near to a peak temperature of 1400°C in a furnace, where metal particles fuse together to produce parts that densify up to 98%.

Single Pass Jetting

SINGLE PASS
JETTING (SPJ)

Metal powder and binder are deposited using Single Pass Jetting technology layer by layer. Depowdered parts are loaded into an industrial furnace where they are heated to temperatures near melting to produce customer-ready parts with densities up to or exceeding 99%.

LASER METAL
FUSION (LMF)

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.

NANOPARTICLE
JETTING

Ultra-fine layers of solid nanoparticle inks are simultaneously jetted from sealed cartridges onto a system build tray. Liquid “jacket” around the nanoparticles evaporate as it is sintered at extremely high temperatures, enabling the dense ultrafine layers to bond.

CERAMICS 3D PRINTING TECHNOLOGIES

LASER STEREOLITHOGRAPHY

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.

NANOPARTICLE JETTING

Ultra-fine layers of solid nanoparticle inks are simultaneously jetted from sealed cartridges onto a system build tray. Liquid “jacket” around the nanoparticles evaporate as it is sintered at extremely high temperatures, enabling the dense layers to bond.
