Facilities
CfAM’s laboratories boast a unique portfolio of developmental and commercially available AM processes, and a state-of-the-art suite of analytical devices in a dedicated materials characterisation laboratory. This laboratory forms a vital tool that facilitates new avenues of both academic and industrially focused research. Among a large research portfolio of commercially deployed AM systems, the laboratory houses specialist and bespoke AM systems that are not available elsewhere in the world. These include experimental multimaterial 3D inkjetting systems, ranging from small scale exploratory research platforms to large scale systems such as the PiXDRO and Toucan, high-temperature liquid metal jetting systems (MetalJet) and custom built multimaterial high resolution AM systems. In addition, our clean room facility (supported by the Wolfson Foundation) widens the palette of materials for 3D inkjet and extrusion printing platforms, and is used primarily for pharmaceutical, biological and electronics orientated research, which needs to be conducted in a setting with a low level of environmental pollutants, or where light sensitive materials are used. The clean room is equipped with a comprehensive suite of 3D inkjetting and analysis equipment, alongside pharmaceutically focused material extrusion systems.
Working on the development of the Additive biofabrication research, Prof Ricky Wildman and Prof Felicity Rose have recently opened a dedicated 3D bioprinting laboratory within the Nottingham Biodiscovery Institute, hosting state-of-art 3D printing equipment for biological applications. These include extrusion 3D bioprinter, stereolithography and projection micro-stereolithography systems, multiphoton lithography 3D printer and dedicated mammalian cell culture areas.
Our bespoke, cutting-edge equipments:
Multi Laser/Material Metal powder Bed Fusion system – AconityMID+
The AconityMIDI+ is an open multi-laser mLPBF system for the production of metal parts. This custom made state of the art system benefits from 3 lasers ranging from 400w to 1Kw with the addition of an Aerosint dual material recoater, InfraTec VarioCAM thermal imaging camera, dual Kleiber pyrometers, 500°c heated substrate and an exchangeable process chambers including additional axis. The open multi laser configuration enables total control of each laser individually, including multiple speeds and powers within a single vector. This total control, coupled with weld pool monitoring via the thermal imaging camera and pyrometers, gives the ability to manipulate and vary the microstructure within a part. This manipulation can be applied to 2 materials within the same part when using the Aerosint dual material recoater. With the additional process chamber, a parallel setup can be prepared to minimise downtime between builds. This additional chamber also benefits from an extra axis which opens up the opportunities for future binder jetting and mLPBF research.
Multimaterial 3D Ink Jetting System – PiXDRO Toucan
The PiXDRO Toucan system is a custom-built £1M inkjet machine constructed for the CfAM by the Dutch inkjet specialist Roth and Rau. The bespoke system has six piezo-electric heads permitting the jetting of six distinct materials within a build process. Additionally, the machine is equipped with a 12 W/cm2 UV curing unit with a wavelength of 395nm, and a 1 KW infrared lamp, with a maximum filament temperature of 1500°C, for curing heat/photo-sensitive polymers and conductive materials. The large build volume is another added advantage of the Toucan system over other conventional inkjet systems available on the market. The CfAM’s current projects on this system are primarily focused on jetting of multiple materials to produce multi-functional 3D components for electrical and electronics, pharmaceutical and biological applications.
Liquid Metal Jetting 3D printing
The MetalJet system is a unique bespoke drop-on-demand 3D printing platform based on the Océ MetalJet technology. This technology enables precision jetting of molten droplets of conductive materials with a melting point up to 2,000°C. The MetalJet system enables the jetting of liquid metal droplets onto a movable substrate to produce 3D parts from a desired stack of 2D digital patterns. Upon solidification, each layer of jetted droplets acts as a new substrate where new droplets can be dispensed to create the subsequent layer. As the process repeats, complex 3D geometries made in single or multiple semiconducting/metallic materials can be printed.
Multi-photon lithography systems
Multi-photon lithography is an advanced Additive Manufacturing technique capable of fabricating arbitrary 3D micro/nano structures without a mask with a resolution of around 100 nm, based on multi-photon absorption-induced polymerisation. There are two system available at CfAM. The commercial Nanoscribe system can fabricate in an area up to 100 x 100 mm2 with a speed up to 10 mm/s. The home-built system has extended capabilities. By combining with optical tweezers, micro/nano-sized objects can be drawn into the vat of material and encased within a matrix or attached to a surface, thus functionalize a surface or a material. By coupling with stimulated emission and depletion (STED), it is possible to control the fabrication of 3D nano-composites precisely through the selective polymerisation or photo-reduction on demand, thus establishing a new route for metamaterial fabrication.
