The Economics of Investment Casting Versus Metal 3D Printing

Production runs of small, intricate metal components have traditionally been addressed by metal injection molding or investment casting. Some manufacturers, however, are finding that advances in 3D printing technology can make it a cheaper and faster alternative.

The question of which manufacturing method is best suited to metal part production can be complicated. It’s not a decision that can be reached by weighing only a single factor. To arrive at the best decision, it’s important for businesses to consider many factors and prioritize.

Are fast lead times essential? Do the components have tensile, strength, or hardness requirements? Is surface finish a major consideration? While it’s important for businesses to weigh various priorities, the final cost-per-part (within quality specifications) is often the deciding factor in which technique wins out.

Metal 3D Printing Processes - Metal Extrusion FFF/FDM

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

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.

PPAP = Production Part Approval Process

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.
