Material Jetting: More Colours, More Detail
While material jetting makes up a small share of 3D printer sales when compared to easier to use technologies like material extrusion (FDM) and powder bed fusion (MJF or other laser-based processes), it isn’t a technology to be overlooked. Producing incredible accuracy and detail in the final product, material jetting has become a go-to solution for prototyping, art, architectural and educational models.
Mimaki’s 3D printers, the 3DUJ-2207 and the 3DUJ-553, both utilise the material jetting method. A piezoelectric printhead travel over the build platform, depositing hundreds of tiny droplets of photopolymer to the desired locations. The material is then cured by a UV LED light, which allows less material warping and more control for complex designs over traditional UV bulbs. The process repeats until the whole part is complete, which is then submerged in water to remove any support material.
As the only 3D printers with the ability to accurately print in 10 million colours, including transparent, up to 1200 dpi, the 3DUJ series can create highly detailed prints. All these abilities alongside its office-friendly size and low noise level have made these machines perfect high-performing models in the 3D printing market.
The Educated Choice
We have already seen examples of Mimaki’s 3D printers' accuracy and colours being used to full effect in universities. The collaboration between Monash University and Erler Zimmer led to the development of anatomically accurate 3D printed medical models to address the limitations of cadavers in education. Initially facing challenges with the fragility and colour reproduction of medical models, the 3D printing industry saw a significant breakthrough with the Mimaki 3DUJ-553. This printer revolutionised the process by accurately creating realistic models with transparent parts to see internal structures. Reliance on cadavers in universities significantly restricts hands-on, interactive teaching opportunities, particularly when it comes to rare pathologies. The ability for universities to produce the desired 3D models as needed, opens up significant learning opportunities for students and medical professionals alike.
The printer's capabilities have also attracted the attention of a team of doctors and researchers from the University of Florence. Facilitating cost-effective solutions and enhancing surgical training and simulation, the technology was also used for a range of anatomical models, reaching a previously unattainable degree of colour fidelity. Meanwhile Canadian company, Biologic Models, has carved out a niche in creating precise and vibrant 3D models of proteins for research facilities and collectors, using the 3DUJ-553 in conjunction with clinical research and x-ray crystallography protein data.
Taking 3D printing beyond the medical, the University of Auckland's Creative Design and Additive Manufacturing Lab (CDAML) uses the Mimaki 3DUJ-553 for vibrant, accurate colour printing in projects ranging from cultural preservation to surgical aids. Initially exploring powder-based printers, the lab shifted to the 3DUJ-553 due to its superior colour reproduction and durability. This printer has helped to transform how students engage with history, engineering, art, and medicine.
The Perfect Tool for the Model Student
Imagine students across the world crafting realistic anatomical models, bringing historical artifacts back to their former glory, or architecting the cities of tomorrow—all with cutting-edge 3D printing technology. In the educational field, 3D printing can equip the professionals of today and tomorrow with the tools they need to better enhance their skills.
