What Xilloc does

Xilloc, legally Xilloc Medical Int, is a Netherlands-based medical device company founded in August 2011 by Maikel Beerens that specialises in patient-specific 3D-printed and CNC-machined implants and surgical aids for craniomaxillofacial (CMF) surgery. Its portfolio spans six core implant product lines — cranial reconstruction in PEEK and titanium (the latter with integrated Interfix fixation), temporomandibular joint (TMJ) reconstruction developed with UMC Groningen, mandibular reconstruction plates, facial augmentation, and orbital floor implants — complemented by surgical aids including patient-specific anatomical models, surgical guides, and the One Stage workflow that combines resection and reconstruction in a single operation. Production is fully in-house at the Brightlands Campus facility in Sittard-Geleen under EU MDR 2017/745 Class III and ISO 13485:2016 certifications, with case management, CT upload, design collaboration, and approval handled through the proprietary Xilloc Portal.

The company monetises on a project-based, quote-priced model: each implant and surgical aid is custom-designed from CT data per case, with PEEK implants delivered within three working days and titanium within five, and urgent cases fulfilled within 36 hours or next-day. The primary customer segments are CMF surgeons (neurosurgeons, craniofacial and oral/maxillofacial specialists) at European university hospitals and in-house hospital 3D labs that outsource certified manufacturing; a secondary B2B channel provides contract manufacturing under Xilloc's ISO 13485 and MDR certifications for third-party medical-device companies that need a legal manufacturer. Distribution runs direct within the EU under MDR and through international agents and distributors elsewhere, with Ovidius Solutions serving the UK market since 2019.

The company is privately held; Holland Capital invested alongside new CEO Milko Wijckmans in 2021 to professionalise operations, the EU MDR Class III milestone was reached in 2025, and a rebranding plus a new Xilloc Portal were announced for 2026. Headcount is in the 11–50 range, and the company has not disclosed revenue or follow-on funding beyond the 2021 round and a small 2015 EISMEA grant.
