Metal 3D Printing Process Overview

3D Printing, or Additive Manufacturing as it less popularly but perhaps more accurately known, is the process of building up objects layer-by-layer, adding material as you go.  Its emergence as a tool not only for prototyping, but also functional applications (e.g., replacement parts, tooling) and production parts (that commonly wouldn't be achievable any other way) provided the inspiration for 3Diligent.  Below are overviews of our different metal additive technologies.  Please click into any of these process options for more information, including additional perspective on our resin, plastic, gypsum technologies.  Or simply submit an RFQ and our team will identify and present the most economical solution that meets the requirements of your particular application.

POWDER BED FUSION

(a.k.a. MPBF, DMLS, SLM, DMP, LaserCUSING)

Selectively melting powdered material with a focused energy source - a laser or electron beam.  This is the most accurate of metal printing technologies before post-processing, allowing tolerances potentially tighter than .005".  Powder Bed Fusion technology also offers tremendous geometric flexibility, including the ability to fabricate "no assembly required" parts with "captured" sub-assemblies that are held in place by unmelted powder until it is removed in post-processing.  It is generally best for parts under a 10" in the X, Y, or Z dimension, although sizes up  to  14" in a given dimension are possible for select materials.

INFILTRATED BINDER JETTING

(a.k.a. BJMI)

The process of spraying an adhesive binder onto powdered material to build up a part, sintering the part in a furnace, and infiltrating that "green" part with a lower melting temperature metal.  Binder Jetting with Metal Infiltration is most commonly done with a stainless steel matrix infiltrated with bronze (see picture above).  Very cost effective but not as high accuracy (tolerances on the order of 1%-3%), Binder Jetting with Metal Infiltration is a great option for complex, traditionally cast geometries (e.g., jewelry).

DIRECTED ENERGY DEPOSITION

(a.k.a. DED, LENS)

Jetting powdered metal into a melt pool created by a focused energy source.  Directed Energy Deposition is a very fast process relative to other technologies, with a rapid deposition and melting rate.  The tradeoff is lower as-built tolerances; design files should typically be provided assuming a 200 micron overbuild to be removed in post-processing.  Because it does not operate as a powder bed, Directed Energy Deposition (DED) is ideal for part repair applications and adding features to existing parts.  Additionally, its faster deposition rate makes it a viable option for ground-up building of larger parts, up to 7 feet in a single dimension.

SHEET LAMINATION 

(a.k.a SDL)

Sheet Lamination involves laying down sheets of metal foil on top of one another, using vibration and tremendous weight to create a bond between the layers, then cutting away excess material.  This metal 3D Printing process does not require heat, making it uniquely suited for embedded sensors.  Additionally, because foil sheets can be readily traded in and out during the fabrication process, dissimilar laminates can be used, making it an intriguing fabrication option for heat exchanger parts.

EXTRUSION

(a.k.a. FDM, FFF, ADAM)

Metal Extrusion involves a heated nozzle processing metal beads housed in a polymer jacket.  The nozzle melts the polymer jacket just enough to lay the material down on the build platform, layer by layer.  The "green" parts are then placed in a furnace where the polymer material burns off, leaving a ~95%-97% dense sintered metal part.

This process is slated to be introduced to commercial markets and offered by 3Diligent in early 2018.

FULL SINTER BINDER JETTING

(a.k.a. BJ, FSBJ)

Similar to Binder Jetting with Metal Infusion, this process involves spraying an adhesive binder onto powdered metal beads, layer-by-layer, to build up a part.  Once the "green" part is built, the part is placed into a furnace where the adhesive is burned off, leaving a dense part.  This process is best for smaller parts, as shrinkage of the green part in post-processing creates challenges with larger geometries.

This Metal Printing process will be offered by 3Diligent in early 2018.
