Binder Jetting
3D Printing
The economical route to small stainless steel parts, up to a 100 mm cube.
What Binder Jetting is good at
Binder Jetting sprays a liquid binder into a bed of stainless steel powder to glue the part together layer by layer, then debinds and sinters it in a furnace to fuse the metal. Nothing is melted during printing, so there are no supports, no residual stress and no witness marks — and the process is considerably cheaper than laser melting for small parts. The trade-off is that the part shrinks substantially in the furnace, so accuracy is proportional rather than absolute.
| Layer thickness | Approximately 0.05 mm in the green (pre-sintered) state |
|---|---|
| Dimensional tolerance | ±0.3–0.4% on features up to 50 mm; ±1.3% above 50 mm |
| Hole tolerance | ±0.5 mm |
| Minimum wall | 1.5–2.0 mm |
| Maximum part size | 100 × 100 × 100 mm — a hard limit (minimum 5 × 5 × 5 mm) |
| Minimum feature | Holes from 1.5 mm; embossed or engraved detail 1.0 mm wide, 1.0 mm deep |
| Sintered density | Typically 96–99% of wrought density |
| Surface finish | Even Ra 4–8 µm, sandblasted as standard |

Where it wins, and where it does not
Every process trades something away. Read the right-hand column before you commit a design — it is the part most services leave out.
Advantages
Why this lane gets picked
- Substantially cheaper than laser-melted metal for small parts
- No support structures at all — geometry is free and no witness marks are left behind
- Nothing melts during printing, so there is no residual-stress distortion from the print itself
- Even, consistent sandblasted surface at Ra 4–8 µm straight off the process
- Parts nest densely in the build box, so batches of small parts price very well
- Full 316L corrosion resistance and good toughness
Limitations to design around
Told straight, before you order
- Sintering shrinks the part by roughly 17–20%, compensated by scaling the model up before printing. That is why tolerance is quoted as a percentage: ±0.3–0.4% up to 50 mm, widening to ±1.3% beyond it. On an 80 mm feature that is about a millimetre — plan fits accordingly.
- The 100 mm cube is an absolute ceiling. Anything larger has to go to laser-melted metal or be split.
- Sintered parts sit around 96–99% dense, so fatigue strength and pressure-tightness are below fully melted metal. Do not use this lane for pressure vessels, high-cycle fatigue or safety-critical loads.
- 316L stainless is the only material offered.
- Long, thin or unsupported overhanging features can sag or distort during the furnace cycle — thicken them or add support geometry into the design.
- Because shrinkage is slightly anisotropic, tall parts can be marginally less accurate in the build direction than across it.
- No material certification is supplied — treat this as a functional and decorative process, not a certified structural one.
