3D Printing Material: Metals

According to the 3D printing,” using plastic has limited scope due to the fragile nature of plastic.  Any serious manufacturing is not possible without using metal.  3D printing using metal or Metal Additive Manufacturing has seen significant growth recently. Metals are 3D printed by melting metal powder using a laser beam to fuse it into a solid part.  Metals used for 3D printing include stainless steel, aluminium, bronze, copper, silver, gold, alloys of titanium, cobalt, titanium, nickel, among others.

3D printing of metals is used in several industries including aerospace, automobile industry, jewellery, medical, among others.  The medical industry, for example, dental and orthopaedics benefits with the ability to customize parts for specific individuals.  The quality of the 3D printed metal objects is comparable to objects made by conventional manufacturing processes.  Manufacturing based on 3D printing results in very little waste compared to conventional manufacturing.  Therefore Metal Additive Manufacturing continues to grow and become a significant part of manufacture”.:)

3D Printing Materials: Metal mixed with ABS or PLA

According to the Some vendors,” they provide filaments based on metal.  These filaments mix metal with ABS, thereby allowing desktop 3D printers to be able to use them.  Most of these filaments can be printed at the temperature similar to PLA or ABS used in the filament.  Examples of these filaments are as follows”.

Bronzefill Filament:  A bronze fill filament is made of eighty per cent bronze and twenty per cent PLA. Having a mix of metal and PLA allows the filament to work with desktop 3D printers.  A bronze fill 3D printed object can be polished to make it shine.  A similar filament is copper fill filament that is made of copper particles mixed with PLA.


Proto-Pasta’s Stainless Steel Filament: A filament called Proto-Pasta’s Stainless Steel combines PLA with finely ground stainless steel particles. The 3D printed object has the steel like properties including weight, density, and texture.  The proto-pasta filament is not stronger than PLA because the steel is in powdered form.  Nor is the proto-pasta filament conductive because the steel particles are separated by PLA.



Proto-Pasta’s Magnetic Iron Filament: Proto-Pasta’s magnetic iron filament is made of PLA and iron powder.  It acts like iron and is attracted towards magnets.  It even rusts like iron.  However, since the iron particles are separated by PLA, the magnetic iron filament is not conductive.


Tungsten Metal ABS Filament: Another metal filament called GMASS Tungsten Metal ABS Filament includes ABS and Tungsten.  Adding tungsten to ABS gives the filament a metal feel and also makes it heavier like metal.  Also, the material has radiation shielding properties.


Bismuth Metal ABS filament:  Another metal filament is GMASS Bismuth Metal ABS filament made of ABS and bismuth.  This filament is also radiation shielding (but contains no lead) and can be used for creating parts for use in medical environments.
