Metal 3D Printing Processes - Metal Extrusion FFF/FDM

Posted by 3DEO on Mar 13, 2018 10:38:02 AM

Overview of Metal Extrusion for 3D Printing

Metal extrusion in additive manufacturing is a fairly new process. Similar to the wildly popular plastic-based FDM process, filament is heated and drawn through a nozzle and then deposited layer-by-layer. This filament is a combination of thermoplastic material and metallic particles. The nozzle moves in the x and y axes across the part for a given layer. The build platform then lowers to make room for new layers. After the part is complete, it is placed into a sintering furnace to burn out the remaining plastic and sinter the metal particles together. Extrusion-based additive manufacturing has been widely used for plastics and polymers, but only recently has developed to create metal parts.

Metal Additive Manufacturing (AM) Processes - Binder Jetting

Posted by 3DEO on Mar 5, 2018 11:20:30 AM

Overview of Binder Jetting

Binder Jetting is a powder bed process that utilizes inkjet technology and a binding agent. The liquid binder is used to “glue” the metal powder together within and between layers. A layer of metal powder is first rolled onto the build tray, and then an inkjet print head moves along the x and y axes and deposits binder in the shape of the part for each respective layer. After each layer is created, the build platform is lowered incrementally to make room for the next layer. The part being printed is supported within the powder bed by the unbound powder, which is then removed to complete the process. The result is a “green part” which then needs to be placed in a sintering furnace to achieve final part density.

Intro to Metal 3D Printing Processes - Powder Bed Fusion (DMLS, SLS, SLM, LMF, DMP, EBM)

Posted by 3DEO on Feb 27, 2018 11:17:35 AM

Overview of Powder Bed Fusion - Metal 3D Printing

Powder Bed Fusion is a popular technique for metal additive manufacturing and includes two main technologies: Laser Sintering and Electron Beam. These techniques are grouped together since they each begin with a layer of metal powder being rolled onto the build tray, and then an energy source (laser or electron beam) fuses or melts the powder into deliberate 2D designs. These 2D layers are fused on top of each other to create the 3D object. Electron beams produce more energy than lasers and are chosen to fuse the highest temperature metal superalloys for parts used in extreme conditions such as jet engines and gas turbines.

Metal 3D Printing Ammunition

Posted by 3DEO on Feb 27, 2018 10:43:22 AM

In the firearms community, 3D printing is a topic of hot conversation. Firearms enthusiasts frequently pitch the benefits of additive manufacturing, which allows firms both large and small to rapidly prototype new components and pieces, and bring them to market faster. Hobbyists have been watching the pricing of AM equipment fall, some hoping that they can one day print complete firearms at home. As the saying goes, they want to "be able to produce AR-15s at home using 3D printers they paid for in Bitcoin..."

3 Tips for Meeting Consumer Demand for Mass Customization

Posted by 3DEO on Nov 7, 2017 9:00:00 AM

Manufacturers are making headway in mass customization thanks to lean manufacturing, just-in-time inventory, and digital technologies like additive manufacturing.


Customizable consumer products can create production choke points in traditional manufacturing models. Additive manufacturing is one way to “unchoke” production for mass customization.

PPAP = Production Part Approval Process

Posted by 3DEO on Oct 24, 2017 9:59:52 AM

If you supply production parts for the aerospace or automotive industries, PPAP is an acronym that you will hear about a lot.  PPAP stands for Production Part Approval Process, and it’s the mechanism buyers in the supply chain use to gain confidence in component supplier’s production processes.  This happens by establishing a reliable and repeatable production process, certified by the customer, that identifies and mitigates risks of failures or defects in the end product.
