Desktop Metal Production System

Metal 3D Printing for Mass Production

Created by the inventors of binder jetting and single-pass inkjet technology, the Production System™ is designed to be the fastest way to 3D print metal parts at scale up to tens of thousands of parts per day.

Powered by breakthrough Single Pass Jetting™ technology, the Production System is available in 2 models: The flagship P-50 for mass production and P-1 which is ideal for developing materials and validate new applications.

Description

Introducing the Production System™

The Production System™ from Desktop Metal makes it possible to manufacture complex, high-performance metal parts at high volumes, with the speed, quality, and cost-per-part needed to compete with traditional manufacturing processes.

100x Faster

With speeds up to 12,000cm3/hr — breakthrough Single Pass Jetting™ technology from Desktop Metal makes it more than 100x faster than common quad-laser metal printers and is also over 4x faster than any closest binder jetting alternative. With zero tooling required, it’s the fastest way to manufacture complex metal parts at a mass scale.

20x Lower Cost

Low-cost MIM powder, high throughput, and simple post-processing deliver per-part costs that are competitive with traditional manufacturing processes – and up to 20x lower than today’s metal 3D printing systems.

Features

  • Automated, closed-loop powder handling
  • Semi-automated depowdering
  • Modular build box for continuous production
  • Automated, high-density 3D nesting

Configuration

The system comprises of a Printer, Crosslink Chamber, Powder Station, and Furnace.

The Process

Single Pass Jetting™ (SPJ™) features bi-directional printing where all steps of the print process—powder deposition, spreading, compacting, ballistic suppression, and binder jet printing—are applied with each pass over the build area.

So whenever there is movement, there is printing.

01 |  Print

The full-width print bars containing 16,384 nozzles each, jets work in conjunction with powder spreaders to disperse metal powder and print in a single pass across the build area, jetting 1.5 billions of drops per second.

Metal powder and binder are deposited layer by layer until the entire build volume is packed with bound parts and surrounding loose powder.

2. Crosslink

The build box containing the printed parts is placed into the crosslink chamber and thermally processed to remove solvents and solidify binding agents, strengthening the parts prior to depowdering.

3. Depowder

When the process is complete, the build box is removed and replaced with a fresh box for the next build.

Parts are removed from the completed build box and moved to the depowdering station where it is cleared of any loose powder that remains in channels and crevices in preparation for sintering.


4. Sinter

Heated to temperatures near-melting, the remaining binder is removed causing the metal particles to fuse together and the parts to density.

SOLUTION OVERVIEW
P-50
P-1
Designed to be the fastest way to 3D print metal parts at-scale, the P-50 leverages Desktop Metal’s Single Pass Jetting technology and bi-directional printing to achieve speeds up to 100 times those of laser powder bed fusion technologies*.

Featuring a state-of-the-art print bar with native 1200 dpi, an inert processing environment, and constant wave spreading for print bed uniformity, the P-50 offers the quality, reliability, and economics required for high-volume, end-use applications.
Designed to bridge the gap between bench top development and mass production, the P-1 leverages on Desktop Metal’s Single Pass Jetting technology to offer the same excellent part quality as the P-50 with enhanced process flexibility.

With support for non-reactive and reactive materials at speeds more than 10 times those of laser powder bed fusion technologies*, the P-1 is capable of printing multiple builds per shift and direct process transfers to the P-50.

*Based on published speeds of single-laser, mid-range laser powder bed fusion systems as of August 25, 2020.

High-Resolution Printing

Produce parts with excellent surface finish and incredibly fine features, thanks to the native resolution of 1200×1200 dpi and layer heights as small as 50 µm found in the Production System™.



Uniform Print Bed

Proprietary constant wave spreading technology maintains a consistent powder wave in front of the compaction roller during printing, enhancing density uniformity across the powder bed.

The result?

Greater consistency across parts within each build and from build to build.



Fully Dense Parts

Print customer-ready parts with densities up to or exceeding 99% without the need for infill or a solvent debind step.

With properties similar to casting, parts produced with the Production System™ are suitable for demanding applications where strength is critical.



Low Cost MIM Powders

By using the same low-cost powders used in the MIM industry, gain access to an established powder supply chain with the scale required to support volume production and a variety of readily usable alloys.

As much as 99% or more of the loose powder recovered during the process can be recycled, driving further cost efficiencies while reducing waste.

High Speed Printing

Up to tens of thousands of parts can be printed per day** with the bi-directional Single Pass Jetting™ print technology, which utilizes every pass of the print carriage to build parts, achieving build speeds of up to 100x laser powder bed fusion systems, maximizing productivity.*

*Based on published speeds of single-laser, mid-range laser powder bed fusion systems as of August 25, 2020.
**Management Estimates as of 12/7/2020.



Dense 3D Nesting

The tooling-free, binder jetting process means parts are supported by loose powder and do not require welding to a build plate.

This enables the build volume to be filled with densely nested parts for efficient delivery of high-throughput builds.



Print Reliability

Patented anti-ballistic technology – engineered to reduce powder bed disturbance – drastically reduces variability in the printing process while increasing the longevity of the print bar.

This facilitates reliable prints and ensures excellent party quality.



Print Bar Redundancy

An anti-banding mechanism in which the print bar is re-aligned between layers ensures reliable binder deposition and suppresses defects that would otherwise affect final part quality.

This mechanism eliminates the need for hard, nozzle-based redundancy while improving maintenance accessibility.



Real-Time Print Bed Inspection

Monitor each layer with the overhead camera to determine nozzle performance during printing and detect when automated printhead cleaning is required.

This helps to minimize and prevent part defects within each build.
