UK large-format maker Rapid Fusion has joined Polymaker's PolyCore Hardware Partner network. Two glass-fibre reinforced PETG pellet grades are validated on its PE320 extruder, giving customers pre-tested materials for large robotic printing.
Which materials are validated?
Both grades are PETG with 30% glass fibre. PolyCore PETG-1113 is positioned as a cost-effective grade with improved gelcoat adhesion. PETG-1013 adds UV stabilisation for indoor and outdoor parts. Both ran on the PE320 extruder used on Apollo, Zeus and Medusa.
What does the partnership cover?
The partnership has applied since the start of 2026 and includes validation, technical work, case studies and joint promotion. A first case printed an office table base, 700 × 500 × 1,100 mm, from 20 kg of PETG-1113 in five hours on the Cerberus hybrid system, sliced in AiBuild.
What it means
Validated material and extruder pairings cut the trial work that large-format users otherwise carry themselves, which matters for smaller EU firms without a materials lab. The announcement gives no cost per part or mechanical data, so the business case still needs own testing. This adds to Rapid Fusion's recent activity at Kingston University.
