Direct Printing
High precision 2PP 3D Printing
​The cutting-edge 2 photon polymerization 3D printers of the latest generation eradicate all the aforementioned drawbacks of traditional CNC procedures and micro injection molding.
The printers we use are capable of producing items in the nanometer range with up to 0.2 µm accuracy, thereby offering cost-effectiveness, promptness in delivery, and a competitive edge in prototyping.​Moreover, the additive manufacturing technique facilitates the construction of intricate structures that are arduous to realize with other processes. Changes to the design or configuration of the micro-part can be promptly and efficiently addressed.
Advantages of 2PP over other technologies
Comparison with SLA
SLA (Stereolithography) 3D printing and 2PP (Two-Photon Polymerization) 3D printing are both advanced technologies that use photopolymer resins, but they operate with different approaches and characteristics.
SLA uses a UV laser to polymerize a liquid resin layer by layer, creating 3D objects with high precision and detail. It is particularly well-suited for prototypes and models that require smooth surfaces and high resolutions, but it may be limited in terms of geometric complexity and microscopic resolution.
On the other hand, 2PP utilizes two photons that, when combined, initiate the polymerization of the resin in a much more localized manner, with a focus on the voxel, allowing for extremely high resolution, even at the microscopic scale. This technique is especially advantageous for creating complex and detailed structures on small scales, such as biomedical devices or microcomponents.
In summary, while SLA is ideal for applications involving larger objects with intricate details, 2PP excels at producing extremely fine details at the microscopic level.

2PP's innovative combinations
Casting
By combining 2PP (Two-Photon Polymerization) 3D printing in the first phase with casting in the second phase, the benefits of both technologies are utilized. The 2PP phase offers exceptional precision and resolution at the micro and nanoscale, with resolutions down to 0.2 microns, allowing for intricate microparts. In the second phase, casting enables cost-effective mass production in various materials while preserving the high precision of the 2PP phase. This combination results in complex, high-resolution parts produced at a lower cost, ideal for high-volume production without compromising quality or material variety.
Additional add-ons to 2PP
Micro-injection molding
Among the technologies we apply, we have extensive experience with microinjection molding techniques, which are particularly useful when considering mass production.
Micro injection molding is a precision manufacturing process used to create small, highly detailed parts. It involves injecting material into a mold cavity under high pressure, allowing for the production of complex and intricate components with tight tolerances.
​
Thanks to the integration of 2PP 3D printing, we are able to create highly intricate and complex structures, ideal for mass production in various industries, such as medical, research, consumer electronics, and other sectors, while maintaining tolerances as low as 5 microns.
