Nanoscribe has launched a new IP-PDMS photoresist, a two-photon polymerization (2PP) printing material that can be used to create 3D free-form surface structures of elastomers. The new IP-PDMS photoresist possessesSoftness, flexibility, elasticity, and biocompatibilityIt is customized for applications that rely on typical elastic material properties. Therefore, the photosensitive resin material canWidely applied in various fields in the future, such as 3D printing of cell scaffolds and tissue engineering, 3D structural surfaces, microfluidic devices, and microelectromechanical systems (MEMS)Wait. IP-PDMS has been optimized for Nanoscribe's 3D micro nano machining system and is compatible with mesoscale solutions in 3D micro nano machining
Characteristics of IP-PDMS photoresist:
·The Young's modulus is three orders of magnitude lower than IP-S, 15.3MPa
·High elasticity characteristic, with a tensile elongation at break exceeding 240%
·Characteristics of low refractive index
·No biological toxicity, compliant with ISO 10993-5/USP 87
·High flexibility and toughness materials, widely applicable to different applications

From Leibniz Institute for New Materials Research in Germany（Dr. Ren é Hensel from Leibniz INM, Institute for New Materials, Saarbr ü cken, stated that the IP-PDMS photoresist, which can be directly 3D printed using Nanoscribe, is highly suitable for producing functional surfaces with microstructures. The time-consuming molding process can be omitted by flipping the design into the elastic material, which makes more new designs possible. '
As an organic silicone based elastomer material, IP-PDMS has similar properties to conventional PDMS, making the new IP-PDMS photoresist an ideal printing material for high-precision additive manufacturing of 3D micro nano structures with soft, flexible, and elastic characteristics. The non-toxic characteristics of IP-PDMS (compliant with ISO international standards) lay the foundation for new 3D printing applications in the fields of life sciences and biology. The brand new photosensitive resin is verySuitable for making elastic free-form cell scaffolds and 3D design that mimics the natural features of soft tissues.

Scientists have learned through studying the amazing crawling ability of geckos that each foot of geckos has millions of extremely fine bristles, and each bristle has hundreds of finer micro nano structure branches at the end, which allows geckos to adapt to any surface. Recently, scientists from the Leibniz Institute for New Materials (INM) used Nanoscribe's Photonic Professional system to design various shapes of 3D adhesive micro nano structure motherboards, which were then replicated and molded to ultimately manufacture 3D adhesive micro nano structures. This design is expected to be applied to grasping tasks on industrial production lines, as well as more other applications, including climbing robots for maintenance services or space debris removal systems for orbiting the Earth.

Nanoscribe's maskless two-photon lithography technology has * design freedom and can achieve almost any geometric shape of adhesive micro nano structures. Scientists have specially designed funnel-shaped micro nano structures with wing shaped columnar arrangements using this technology. By adjusting the angle of the wing surface, the adhesion of micro nano structures can be controlled, which can exhibit stronger adhesion under dry conditions and even underwater.
Usually, we use replication technology to manufacture these adhesive micro nano columnar arrays with potential applications. However, the replication molding process limits the design freedom, for example, larger bottom cuts cannot be formed from the mold. The new type of directly printable elastomer material developed by Nanoscribe has opened up new possibilities for advanced design of directly printed elastic micro nano structures in the future.
