What GeSiM does

GeSiM – Gesellschaft für Silizium-Mikrosysteme mbH, headquartered in Radeberg near Dresden, Germany, designs and manufactures modular bioinstruments and microfluidic devices for life-science research, in-vitro diagnostics, 3D bioprinting, and chemical synthesis. The company was founded in 1995 as a spin-off from the Rossendorf Research Center, and over 30 years has built a portfolio centered on piezoelectric non-contact dispensing (the Nano-Plotter microarrayer and 60-500 picolitre drop dispensers up to 1000 Hz), modular 3D bioprinters (BioScaffolder series for pneumatic, piston, and melt-electro-writing of hydrogels, alginate, PCL, and biopolymers), the BioSyntheSizer liquid-handling robot with up to seven independently moving Z-axes, the µContactPrinter for surface patterning and Nano-Imprint Lithography using patented PDMS stamp technology, the MicCell transparent flow-cell system with FluidProcessor, and a microfluidic-workstation benchtop robot. The company also offers contract microfluidic manufacturing services spanning silicon, glass, ceramics, and PDMS, including KOH/ASE/HF etching, PVD/PECVD deposition, anodic and fusion bonding, and wafer dicing up to 6-inch diameter.

GeSiM serves four primary use-case segments: life-sciences research and IVD diagnostics (including FDA-certified HPV and tumour-marker array production at customers such as Genetel Korea and Sunlant China), 3D bioprinting and regenerative medicine (TU Dresden, FAU Erlangen, University of Otago, Bellaseno), microfluidics and organ-on-a-chip (Fraunhofer IWS, TissUse), and automated chemical synthesis (Leibniz IPF Dresden, TU Dresden B-Cube, McGill). Revenue is generated primarily through configured-to-order hardware sales (Nano-Plotter, BioScaffolder, BioSyntheSizer, µContactPrinter, MicCell, Microfluidic Workstation), professional engineering and customization services, and microfluidic device manufacturing. Pricing is quote-based and undisclosed; pre-sales feasibility tests, post-sales upgrades, and after-sales service are emphasized as differentiators.

Distribution is a hybrid direct-sales and channel model. GeSiM sells directly in Germany and to accounts without local representation, while 14+ international distributors cover North America (ScieCon), Australia/New Zealand (Bio-Strategy), China/Taiwan (Yizhi Technology, Cold Spring Biotech, Jiangsu Huaxinde, Genn Dih), France (Proteigene), Hungary (Bio-Science), India (MediSpec), Japan (BM Equipment), Korea (Bio-Medical Science), Singapore (Sciencescan), and UK/Ireland (Analytik). Marketing relies on industry conferences (LOPEC, TERMIS, Biofabrication, MEDICA), product-segmented newsletters, LinkedIn/YouTube/Facebook, peer-reviewed publications, and customer symposiums. The Managing Director is Dr.-Ing. Hendrik Fiehn; the company remains privately held and non-public with no disclosed external investors or subsidiaries.
