Additive Manufacturing (AM)

Renishaw AM250 Additive Manufacturing System

Flexible material use and ease of changeover
The AM250 features an external powder hopper with valve interlocks to allow additional material to be added whilst the process is running. It is possible to remove the hopper for cleaning or to exchange with a secondary hopper for materials change, using the universal silo lift. This means that multiple material types can be interchanged on the AM250 platform with relative ease. The powder overflow containers are outside the chamber and have isolation valves so that unused materials can be sieved and reintroduced to the process via the hopper while the system is running. The system has a build volume of 250 mm × 250 mm × 300 mm.

Utilizing a high-powered fiber laser to print 20µm- to 100µm-thick layers of fully dense metal directly from 3D CAD data, the Renishaw AM250’s fine metal powder melting process offers fast additive manufacturing for metal parts.

The AM250’s new third-generation, state-of-the-art technology includes a safe-change filter system to reduce contact with materials. This helps maintain an ultra-low oxygen content in the build atmosphere.  

Many features of the AM250 minimize the cost of ownership, including low gas consumption, affordable filter elements and a durable soft re-coater blade that needs to be replaced less frequently than other models. Designed for ease of use, the touch-screen interface allows users to prepare and clean the printer.   

The ability to quickly change between a diverse array of materials is one of the strongest features of the AM250. Utilizing the AM250’s removable hopper, users can switch between 316L and 17-4PH SS, H13 tool steel, aluminum AL-Si-12, titanium CP, Ti 6AI-4V and 7Nb, cobalt-chrome (ASTM75) and Inconel 718 and 625. The valve interlock system allows for the addition of extra powder during prints. Further, the hazards of sooty emissions and using reactive materials like titanium and aluminum are minimized with the inclusion of a gas knife and a heated build plate.

With a build envelope of 250 mm (X-axis) x 250 mm (Y-axis) x 300-360 mm (Z-axis), the AM250 comes with a 200W or 400W laser and a fully-welded vacuum chamber for low-pressure evacuation. The chamber keeps oxygen concentrations below 50 ppm through low gas consumption to enable safe use of reactive materials, which also allows for better overall mechanical performance and material integrity. 

Users can choose Marcam Autofab or Materialise Magics software to create and upload build files to the machine via a secure network or direct connection. Customers can also trace past products through enhanced process data and event logging, which are now standard features on the AM250. There are more options to customize the AM250, which are available upon request. 

Renishaw AM400 Additive Manufacturing System

AM 400 system

The Renishaw AM 400 is the latest development of the
Renishaw AM platform. It features all the most recent PlusPac
machine updates including larger safe change filter, improved
optical control software, revised gas flow and window
protection system and a new 400 W optical system to give a
reduced beam diameter of 70 µm, in line with the current
AM 250 200 W platform.

The advantage offered by the AM 400 is the possibility to
develop parameters that deliver higher productivity through
faster scan speeds, whilst still maintaining feature definition
and precision. An additional benefit is the direct transferability
of existing 200 W material file parameters from the AM 250
200 W system. The increased laser power of 400 W focussed
at 70 µm also provides the potential to process materials with
elevated melting temperatures, with a significant increase
in energy density compared to the current AM 250 400 W

• Build complex metal components direct from 3D CAD data
• Transferable parameters from AM 250 200 W to AM 400
• Flexible and rapid material changeover
• Class leading patented inert atmosphere generation and
low argon consumption
• Open access material parameter editing
• Soft recoater blade suited to lattice and delicate geometries
• Patented SafeChange™ filter system
• Build removal via chamber glove box enhances safety

Additive manufacturing benefits

• Component weight reduction - only build
material where required for optimised part
• Rapid design iterations
• Bespoke or customised items
• Multiple parts consolidation
• Reduce tooling costs
• Build complex geometries such as thin
walls, lattices and internal features
• Increased design freedom - AM is not
constrained by traditional design rules

Flexible material usage
The AM 400 features an external powder hopper with valve
interlocks to allow additional material to be added whilst the process
is running. It is possible to remove the hopper for cleaning or to
exchange with a secondary hopper for materials change, so multiple
material types can be interchanged with relative ease.
The powder overflow containers are outside the chamber and have
isolation valves. This allows unused materials to be sieved and
reintroduced to the process via the hopper while the system is

Class leading inert atmosphere and minimal gas consumption
Renishaw’s patented class leading inert atmosphere generation
works by first creating a vacuum before back filling with high purity
argon gas. This method ensures a high quality build environment as
well as minimal argon usage for atmosphere generation, suitable
for all qualified metals including titanium and aluminium. Gas
consumption is further minimised by the use of a sealed and welded

Open parameters and materials
Renishaw follows an open parameter ethos, providing our customers with freedom to optimise machine settings to suit the
material being processed and the user’s specific part geometry.
With Renishaw’s support you can benefit from the freedom to develop your own parameters for your own materials and your
specific part geometries without compromising your warranty.
Renishaw supplies a range of high quality metal powders including Ti6Al4V ELI, AlSi10Mg, stainless steel 316L, tool steels,
nickel alloys and cobalt chromium alloy.

The Renishaw QuantAM file preparation software has been developed by our experienced team of software engineers
specifically for use with Renishaw additive manufacturing systems. QuantAM is designed to be simple to learn and intuitive to
use and is an ideal product for new users. More information is available in our QuantAM brochure.

Renishaw RenAM - AM500 Additive Manufacturing System

Additive manufacturing for industrial applications
The RenAM 500M is a laser powder bed fusion additive manufacturing system designed specifically for the production of metal components on the factory floor. It features automated powder and waste handling systems that enable consistent process quality, reduce operator touch times and ensure high standards of system safety. The system build volume is 250 mm × 250 mm × 350 mm.

The RenAM 500M is built using a Renishaw in house designed and manufactured optical system and control platform which forms the basis for our future additive manufacturing systems product range.

Ideal for industrial production applications, RenAM 500M has a higher level of automation compared to the more flexible AM250 and AM 400 platforms.

Powder sieving and recirculation are all carried out within the compact system automatically, reducing the need for manual handling and exposure to materials. This provides increased safety and sustained quality of the metal powders.

The large 19 inch robust touchscreen user interface, and machine control software has been designed to be intuitive. Based on a Windows® operating system with a dedicated user interface, large icons show the build set-up workflow for ease of navigation through the various process steps.

The patented high capacity dual SafeChange™ filter system enables builds to be run for long periods within a stable controlled atmosphere. The filters capture process emissions in a safe and efficient manner.

The intelligent control system actively senses the condition of the filter, and automatically redirects the gas circuit to the clean filter before the process conditions deteriorate. The user is then alerted to change the filter housing and replace the filter cartridge.
