Our best estimate for a metal additive manufacturing in this class — not a quote from Renishaw. Configuration moves it a long way.
Overview
The Renishaw AM400 is a laser powder bed fusion machine listed with one 400 W laser and a build volume of 250 x 250 x 300 mm (9.8 x 9.8 x 11.8 in). It is not in Renishaw's current lineup, and the listed figures have not been checked against a maker document, so treat them as a guide when assessing a used system.
The process rows give a focus diameter of 70 µm or 80 µm, depending on the beam shaping option, and a layer thickness of 20 - 100 µm that varies with the material. The laser is a Yb-fiber type. The chamber runs under nitrogen or argon, and powder is handled in a contained system with a SafeChange filter and internal sieving, an arrangement meant to limit operator contact with loose powder.
One listed item is aimed at development work: a 78 x 78 mm reduced build volume insert, named QuantAM RBV, for parameter development. It lets a trial run on a small charge of powder without filling the full 250 x 250 mm bed. The materials row names Ti6Al4V, IN718, CoCrW, 316L, AlSi10Mg and Maraging Steel 300. Build preparation software is QuantAM, and InfiniAM real-time process monitoring is listed.
Against the RenAM 500S the AM400 has the same bed and less height, 300 mm against 350 mm, and its laser is 400 W where the RenAM 500S has 1 × 500 W. The table has no rows for machine weight, footprint, power supply or gas consumption, so those need to come from the documents of the system on offer.

Strengths & Limitations
Strengths
- Build volume of 250 x 250 x 300 mm (9.8 x 9.8 x 11.8 in) with a 400 W laser
- Focus diameter of 70 µm or 80 µm, according to the beam shaping option
- 78 x 78 mm reduced build volume insert (QuantAM RBV) for parameter development on small powder quantities
- Contained powder handling with a SafeChange filter and internal sieving
- Runs under nitrogen or argon, with InfiniAM real-time process monitoring listed
Limitations
- Number of lasers is 1, so a single 400 W beam exposes every layer of the bed
- Build height is 300 mm (11.8 in), against 350 mm on the RenAM 500S
- The listed figures have no maker document behind them, and the table lacks weight, footprint, power supply and gas consumption rows

Frequently Asked Questions
01
The listed build volume is 250 x 250 x 300 mm (9.8 x 9.8 x 11.8 in). A reduced build volume insert of 78 x 78 mm, listed as QuantAM RBV, is available for parameter development, so small trials do not need the full bed charged with powder.
02
The materials row names Ti6Al4V, IN718, CoCrW, 316L, AlSi10Mg and Maraging Steel 300. The inert atmosphere is nitrogen or argon, and layer thickness is listed as 20 - 100 µm depending on the material.
03
One 400 W Yb-fiber laser. Focus diameter is listed as 70 µm or 80 µm, the two values belonging to different beam shaping options. Find out which option a used machine has, since the table does not say which is fitted as standard.
04
Both have a 250 mm square bed. The AM400 is listed with 300 mm of build height and a 400 W laser; the RenAM 500S has a build volume of 250 mm × 250 mm × 350 mm (9.8 in × 9.8 in × 13.8 in) and 1 × 500 W of laser power.
