Competition overview

Open Chair is an international ideas competition organised by Creathlon Competitions in partnership with Aibuild.

It invites architects, designers, engineers, makers and creative thinkers to design a full-scale chair that can be fabricated using a standard home FDM 3D printer, assembled with minimal tools and shared digitally for others to reproduce.

The competition explores the intersection of design and digital fabrication, challenging participants to balance design quality with printability, assembly logic, structural intent and reproducibility.

Participants are encouraged to rethink how furniture can be designed, fabricated and shared through the principles of Open Design.

Information on how to enter is available on the competition’s website.

Eligibility and judging criteria

Open Chair is open worldwide to students, graduates, professionals, designers, architects, engineers, makers and other creative disciplines, entering either individually or as part of a team.

All participants must be 18 years of age or older at the time of registration.

Participants must design a full-scale chair intended for fabrication using a standard home FDM 3D printer. The design must be divided into printable components that fit within standard printer build-volume constraints and assemble into a self-supporting chair.

Required submission materials include two STL files (assembled chair and printable parts), an A2 landscape presentation board detailing design visuals and assembly guides, a project description of up to 500 words, and an A2 portrait poster showing the final design image.

The proposals will be judged on:

• Printability and system logic: how effectively the chair is divided into printable components and responds to the constraints of home 3D printing
• Assembly and clarity: the quality and sophistication of the assembly strategy, connections and communication
• Functionality and stability: whether the chair demonstrates a believable structural strategy and can realistically stand independently and maintain its intended form
• Design quality and intent: the strength of the design concept, form, proportions and overall resolution
• Accessibility and reproducibility: whether others can reasonably understand, reproduce and build the design using accessible tools and equipment

Submission deadlines

Registration closes on 22 October 2026, and the final project submission deadline is 6 November 2026.

Winners will be announced on 12 January 2027.
