Multi Jet Fusion, a technology introduced by the HP company, brings a real revolution to 3D printing of functional products. Discover a new technology that dramatically reduces the delivery time, offers high level of detail and excellent mechanical properties for functional prototypes and series production
Technology
Over the last 30 years, there have been many different technologies and materials developed in 3D printing. Recently, many innovations break all the historical records. That is why it is important to understand your needs and choose the best solution for your application.
DMLS/SLM
Both SLM and DMLS technologies work similarly to SLS, but they use fine metal powder as the initial material instead of polymer granules.
DMLS does not melt the powder, but heats it up to a temperature close to melting point where molecular bonds are created. This technology is used for additive manufacturing from alloys.
SLM uses a high-performance laser to completely melt the material and thus creates a homogeneous product. SLM works with pure metals.
SLA/DLP
SLA is the very first 3D printing technology, developed in 1986. It uses photo-sensitive polymers (resins on the basis of epoxy) which are hardened by a UV beam.
DLP is a similar technology to SLA where hardening works on a blanket basis, always one whole layer at a time. This is done by a UV projector.
Both technologies are characterised by an extremely high surface quality. Technologically, they require printing of supports which maintain the dimensions and shape of the product.
FDM/CCF
FDM is currently the most well-known and widespread 3D printing technology which melts a plastic spool and a nozzle applies it on a build platform.
CFF is a technology patented by the Markforged company. It allows to strengthen the basic plastic material by layering continuous kevlar, glass or carbon fibres. It creates composite products with extremely high strength.
