Defiant3D launches Defiant200 budget metal Additive Manufacturing machine
Defiant3D, an Additive Manufacturing machine maker based Aberdeenshire, Scotland, has launched its first metal AM machine, the Defiant200. Based upon a novel Cold Deposit and Sinter technology, the new machine is marketed as an affordable entry into metal Additive Manufacturing.
The patent-pending Cold Deposit and Sinter (CDS) process has been developed over the last five years, led by company founder Gary Cairns. At the heart of the Defiant200 is a furnace, capable of reaching 1400°C. Inside this furnace is a Z-axis build plate, onto which two powders are deposited using a print head moving in the X and Y axis a layer at a time. One of the powders is the primary metal, the other is a support powder.
Once all layers have been deposited, the Z axis retracts to the bottom of the furnace and the lid of the furnace is closed. The furnace is heated to a temperature at which the metal powder sinters together to form the object, whereas the support powder – with a melting point above that of the metal – remains as a powder.
Once the furnace is cooled, the metal object can be removed from the support material and post-processed as required.
The Defiant200 is a compact, all-in-one system, measuring just 107 x 82 x 185 cm and requiring a 16A, 240V single-phase AC power supply. It has a build volume of 200 x 200 x 200 mm and can process parts in stainless steel 316L, with other materials planned to be introduced in the future. The print head deposits the powder in layers of between 100 and 300 microns.
In addition to supplying the Additive Manufacturing machine, Defiant3D also plans to offer metal powder and support powder. The company has also developed its own dedicated slicer software.
The Defiant200 is currently available for pre-order at a price of £40,000, with shipping expected to begin in the first quarter of 2024.
