3D-Printed Silicone for Neuroscience: The 3Brain Case Study

What's inside

When Precision Silicone Meets Neuroscience

Recording electrical activity from living neural tissue demands more than advanced electrodes. Biological samples must remain stable, undamaged, and in close contact with the recording surface. For 3Brain's CorePlate™ technology, achieving this balance required a delicate silicone component capable of applying gentle, controlled pressure while allowing culture medium to flow freely.

In this case study, discover how Spectroplast used its TrueSil A35 medical-grade silicone and additive manufacturing technology to produce a precise, biocompatible silicone net for 3Brain's sample holder system. Explore the design challenges, material requirements, and real-world results behind a component that supports reproducible neural recordings.

• Understand why soft, chemically inert, and precisely manufactured components are essential for reliable neural recordings.
• Explore how TrueSil A35 enables intricate, biocompatible silicone nets with consistent geometry and gentle mechanical contact.
• See how the silicone net supports stable sample positioning with a calibrated hold-down force of 250–1,250 µN in 3Brain's CorePlate™ systems.
