Stereolithography (SLA) is ideal for manufacturing high detail parts with fine details in a wide range of resins from rigid, flexible to transparent. Forge Labs uses 3D Systems industrial vat polymerization SLA printers, which offer exceptional mechanical properties, high tolerances and uniform surface finish. These industrial SLA 3D printers require very little supports to support parts, resulting in no visible support touchmarks. This technology is ideal for medical devices, master patterns, microfluidics, movie props, art, molds and lots more.

How It Works

Parts are manufactured inside a vat of resin that is cured using a UV laser to form a solid object. There are two types of Stereolithography printers: Inverted and non-inverted 3D printing. Forge Labs uses non-inverted SLA 3D Printing as it significantly reduces peeling forces between each cured layers resulting in less deformation,  stronger parts and a significantly better surface finish as no support defects are leftover.

Applications

Choose SLA technology when you need to produce prototypes, master patterns, or high detail concepts. The biggest advantage of this technology is the ultra smooth surface it offers and the excellent print resolution and accuracy.

Fused Deposition Modeling (FDM) is the most widely known and commonly used 3D printing technology. It has been around since 1989 is typically the technology people associate most with 3D printing. Industrial FDM 3D printers are a little different than the smaller desktop machines popularized in the past decade. Forge Labs uses Stratasys Industrial 3D Printers, which offer large build volumes, as well as excellent mechanical, exceptionally high accuracy and repeatable results.  Due to the fully enclosed and heated build chamber, FDM is capable of producing parts with the tightest tolerances in the 3D printing industry in a very wide range of thermoplastics suitable for functional applications from subsea, to automotive to aerospace.

How It Works

Thin filament is melted by a high temperature extruder and deposited onto a build platform inside of a heated build chamber kept just below the melting temperature of the thermoplastic being printed with. Stratasys FDM printers use two print heads, one for model and one for support. Once builds are complete, support is dissolved off in a ultrasonic cleaning tank requiring no manual removal of supports and no defects leftover on the part.

Applications

Choose FDM when you need strong, functional parts that are dimensionally stable in a wide range of thermoplastics. The material is most popular for its ability to build in specialized materials useful for medical devices, electric static dissipative parts, high temperature applications or applications where Flame, Smoke Toxicity (FST) ratings are critical.

Multi-Jet Fusion (MJF) by HP is the newest additive manufacturing technology to enter the market and our lineup. Developed by Hewlett-Packard, HP's MJF offers unparalleled manufacturing speed as it uses an array of inkjet print heads to deposit fusing agents onto a bed of polymers allowing for blazingly fast print speeds. This makes MJF a very capable substitute for injection molding, leading to lower production costs, and faster turnarounds. Parts that are printed using MJF 3D printing are fully dense, watertight and offer consistent mechanical properties without the highy visible layers seen in other 3D printing technologies.

How It Works

Parts are manufactured in a bed of polymer powder that is fused together via a inkjet array of sintering and detailing agents that selective fuses it together. After each pass of sintering agents, a recoater deposits another thin layer of powder over the bed in 80 micron layers until the process is complete. Parts are then cooled between 24-48 hours and then extracted from the bed of polymer powder, sorted, and bead blasted to remove any excess powder.

Applications

Choose MJF when you need to produce high quantities of complex functional parts. Parts can be stacked in both X, Y & Z allowing for every corner of the build volume to be utilized offering excellent part throughput. We recommend taking advantage of MJF's 3D printing speeds when you part quantities required are in excess of 100 units as the larger build volume tends to make it a less accurate and efficient than Selective Laser Sintering for smaller quantities.

Direct Metal Laser Sintering (DMLS) is ideal for manufacturing fully dense, functional & complex metal parts and prototypes.  Part are produced additively using a laser that selectively sinters metal powder, layer by layer to form a homogenous part. This technology is ideal for simplifying multi part assembles into a single part, or producing lightweight, hollow parts with internal channels not possible by traditional methods. This makes the technology popular in automotive and aerospace manufacturing where the manufacturing flexibility of DMLS allows for parts to be produced lighter and stronger, increasing the efficiency of the vehicle or aircraft.

How It Works

Parts are manufactured in a bed of metallic powder that is selectively sintered together via a high powered laser to weld each layer together. After each sintering stage, a recoater arm passes more metal powder over the bed in 40 micron layers. The process is similar to Selective Laser Sintering, however parts cannot be stacked in Z as they require supports to adhere it and stabilize the part to the build platform.

Applications

Choose DMLS when you need to produce low volumes of highly complexity,  end use metal parts of geometries that cannot be easily machined. This technology is typically more expensive than machining, however it does unlock more design possibilities allowing for geometries to be built not previously possible with traditional manufacturing methods.
