The Idea

© Xact Metal, Inc.

Problem #1 - Currently Powder-Bed Fusion can only produce parts in a single material

Solution: Support metal powder-bed fusion in multiple materials instead of being limited to one material

Customer Problem

“Pricing within the 3D printing industry needs to be ‘meaningfully lower’ than where it is today to drive adoption … In fact, pricing remains the most important factor which is holding back 3D printing adoption …” - Matthew Cabral, Equity Research at Goldman Sachs

• Industrial and research customers who would like to enter metal 3D printing cannot do so profitably due to the high acquisition and usage costs

• A lower-priced unit, which does not sacrifice performance, would allow more customers to enter the metal AM space.

• There is a segment of customers whose needs are unmet at these higher printer and powder prices.

Our Products

XM200C The XM200C makes quality metal powder-bed fusion available for universities, labs and small-to-medium businesses who need prototyping, tooling capabilities, or low volume casting alternatives.

XM200S The XM200S is ideal for printing of small parts where high-performance metal powder-bed fusion applications and print speed are critical.

XM300C The XM300C offers an expanded print area for larger, industrial metal powder-bed fusion applications that need prototyping, tooling capabilities, or low volume casting alternatives.

Leading Technology

Xact Core™ Built on the patent-pending Xact Core, a high-speed gantry system platform that allows light, simple mirrors to move quickly and consistently above the powder bed on an X-Y axis.

• Avoids the use of complex galvanometer mirrors and F-theta lenses

• Maintains a constant laser angle across the whole build plate

• A simplified gas flow over the powder bed due to the smaller build chamber

Patent-Pending Recoater • Unique “bulb” shape of the recoating element spreads powder like a blade,

yet provides compaction similar to a rolling element

• Compliant design allows the recoater to negotiate out-of-plane growth and continue printing

• Mounting the recoater to the machine lid allows the entire recoating mechanism to be removed from the build chamber

• Easy access to the build chamber allows for simple recoater replacement and adjustments

Intuitive Touchscreen User Interface The modern, interactive graphic user interface (GUI) for the XM300C makes loading files, setting up builds and monitoring the build process quick and easy.

• Home screen displays real-time build monitoring with two cameras

• Chamber setup screen allows customer to optimize print parameters

• Build queue screen provides a description of all builds to be printed

• Monitoring screen shows behavior of important parameters such as bed temperature, chamber temperature and pressure and oxygen percentage
