✽Aluminum’s Oxides pose a challenge in the sintering process and it needs more than just an oxygen-free environment. Aluminum and its alloys can only be effectively sintered in pure nitrogen or in a vacuum. Argon has been used in the past, but can create some bonding issues between particles. There are conditions that aluminum requires depending on the alloy and geometry. Simple aluminum alloys such as 2014 can be sintered in dry nitrogen, but the furnace needs to be tight (-50 dewpoint) and uniform (±1°F) temperature control.
✝Oxygen is damaging to the metal sintering process. Sintering Carbon is used to combat this. Titanium is extra troublesome because it absorbs oxygen like crazy. It will pull oxygen out of a standard kiln’s insulation. Compounding the issue is titanium’s reactivity in the presence of oxygen and heat. The solution that we understand today is to use an all-metal kiln and a chamber thoroughly flooded with ultra high-purity argon.

SINTERING KILN
Sinter printed metal and ceramic objects with the click of a button.
These systems allow Partner Innovators to sinter a number of The Virtual Foundry 3D printed materials including Ceramics, Bronze, Copper, 316L Stainless Steel, 17-4PH Stainless Steel, Inconel 718, and more in development!
How it works: 3D Print, Pack, Sinter, Metal! You “pack” the printed part in a Sintering Refractory Ballast and load the part in the Kiln. Select the parameters for sintering, click start and your parts will soon turn to functional metal objects! Follow the sintering instructions included with the kiln to turn your printed parts into metal. This kiln allows for your choice of inert gas or open environment sintering.
