Binder Jetting Metal

Promising for higher-volume metal parts post-sintering. Industrialization slower than early hype suggested. Active production deployments in automotive and industrial sectors.

How it works

An inkjet printhead deposits a liquid binder onto a bed of metal powder, selectively bonding each layer. The green part is then de-bound and sintered in a furnace to achieve near-full density. No laser or beam energy during printing; high throughput potential since the entire powder bed area can be used simultaneously.

Also known as: ExOne, HP Metal Jet, Desktop Metal Production System

Materials

316L stainless, 17-4 PH, 4140 steel, M2 tool steel, Ti-6Al-4V, IN625

Strengths
  • 01No support structures required (unsintered powder supports parts)
  • 02High throughput — pack entire build volume with parts
  • 03Finer surface finish than LPBF in many cases (smaller powder particles)
  • 04Economically attractive at higher production volumes
  • 05No residual stress from thermal gradient (no melt pool)
Bottlenecks
  • 01Sintering distortion requires calibration and compensation — dimensional control is challenging
  • 02Separate sintering step adds lead time and capital cost
  • 03Materials qualification library narrower than LPBF
  • 04Sintering constrains part size (shrinkage must be predicted accurately)
  • 05Several vendors (Desktop Metal, ExOne) faced financial and market challenges 2022–2024
Key Applications
  • 01Automotive structural and functional metal parts (GM, Volkswagen)
  • 02Industrial tooling and fixtures
  • 03Consumer products metal parts
  • 04Firearms components
  • 05Medical device metal parts
Key Suppliers

• HP (Metal Jet S100) — Production-scale• collaboration with BMW, VW, JLR• Desktop Metal (Production System) — High-throughput• financial challenges 2023–2024• Markforged Metal X (bound metal) — Desktop-scale bound metal• related but different sintering approach• ExOne / Desktop Metal — Acquired by Desktop Metal• X1 25Pro and X1 160Pro• Digital Metal (Höganäs) — High-precision micro-binder jetting

Trajectory 2025–2035

Production deployments expanding in automotive and consumer goods where volume justifies sintering infrastructure. Materials library growing. Key challenge: demonstrating consistent dimensional control at production scale. Consolidation among vendors likely to continue.
