4Degra® resin-inks (available now)
4Degra® resin-inks are available now in both standardised and bespoke ‘Technical Grades’ (T series) for use in research and development projects.
By tuning the chemistry and formulation of our resins we can achieve a wide range of physical properties, shape memory behaviour and degradation-time profiles in the finished 3D printed parts made from them.
Our standardised product range includes ‘soft’ T15 and ‘hard’ T800 variants with tensile elastic moduli of 15 MPa and 800 MPa respectively. Higher modulus grades are also under development. The following table presents the key properties for the T series resin-inks:
|4Degra® T15 series||4Degra® T800 series|
|3D printed material |
|Ultimate tensile strength||2 MPa||25 MPa|
|Tensile modulus||15 MPa||800 MPa|
|Strain at break||150%||50%|
|Toughness||250 MPa•m-2||750 MPa•m-2|
|Glass transition temperature||0°C||88°C|
|Resin-ink properties||Curing wavelength||365-405 nm||365-405 nm|
|Standard colour||Orange – colourless||Orange – colourless|
|Viscosity||5 Pa.s||5 Pa.s|
Standardised 4Degra® resin-inks have been optimised for use in a leading DLP 3D printing machine platform, further details of which will be announced soon.
Bespoke grades of 4Degra® resin-ink can be developed to suit a particular application and 3D printing system.

Implantable medical devices
With their unique range of properties, our 4Degra® resin-inks have clear advantages over the next-best alternatives in numerous biomedical applications.
The ability to 3D print complex scaffold designs and other implantable medical devices with fine resolution (down to 5 microns in the Z axis, and 2 microns in the X and Y axes) and shape memory functionality, offers our collaborators limitless product development potential.
In collaboration with business partners from the 3D printing and medical device sectors, we are currently developing target product concepts for a range of indications, ranging from implantable micro-devices to tibial fracture repair devices. We are keen to work with more collaborators in this way, so if this of interest, please get in touch.
In parallel with our collaborative developments, and with funding support from Innovate UK, we have also been working on our own brand medical device concepts, of which the 4D Conserva® breast conserving lumpectomy device is the most advanced.
Having independently validated the market opportunity and promising clinical adoption prospects for the 4D Conserva® device, we are now keen to find business partners to help us complete product development, undertake clinical trials, regulatory approvals and full commercialisation.
