Fixie 3D FAQs

Fixie 3D specialises in architectural 3D printing and model making. Their London-based studio combines precision SLA printing with expert craftsmanship to produce concept, planning, and marketing models. Whether you need a scaled building mock-up, façade study, or city masterplan, Fixie 3D handles every stage — from file preparation and printing to painting, assembly, and mounting.

The studio primarily employs laser-based SLA 3D printers, known for their precision and clean surface finish — ideal for architectural applications. Prints can be sanded, primed, and painted to mimic materials like metal, concrete, or glass. Fixie 3D also integrates traditional model-making techniques for advanced textures and visual realism.

Their industrial SLA printers support build volumes up to 750 mm wide × 750 mm deep × 550 mm high. For oversized projects, models are split into multiple printed parts and seamlessly assembled in-house. This flexibility allows creation of large architectural masterplans or modular site models with perfect alignment.

Many architectural CAD or BIM files aren’t print-ready. Fixie’s technicians check and repair 3D data using professional tools like Materialise Magics. They close gaps, remove errors, and optimise geometry for 3D printing. File-fixing is priced separately, based on the complexity and model scale (A6–A1 tiers).

Architects can export models from tools like Revit, Rhino, AutoCAD, or SketchUp into STL, OBJ, or FBX. The Fixie team can also convert raw CAD/BIM data and handle complex assemblies. If unsure, you can send native files, and their engineers will advise on export settings and scale conversion.

Fixie’s pricing model includes three components: (1) File-fixing fee based on model size (A6–A1 tiers), (2) Material usage cost per cubic centimetre of resin used, and (3) Optional finishing such as painting or mounting. VAT and delivery are charged separately. Exact quotes are provided after reviewing your model files.

Fixie 3D offers quick production through a network of industrial printers in London. Simple small-scale prints may take 2–3 days, while complex or large painted models can require up to 10–14 days. Urgent deadlines can often be met — the team encourages clients to share target dates when submitting files.

After printing, each component is sanded, primed, and painted using durable coatings that mimic realistic finishes like concrete, glass, or metal. Models are assembled by hand, often mounted on display bases or site boards, ensuring presentation-level quality for client meetings or competitions.

Their “site plug” system allows you to create interactive architectural models that evolve with your project. Each plug represents a building or phase; new updates can be reprinted and swapped without remaking the entire model. Note that each additional plug increases material usage and overall cost.

All models are produced in their Wembley studio. Clients can collect models directly or request delivery. Shipping fees vary based on size, packaging, and destination. Fixie can also create travel-friendly models suitable for flights and competition transport.

To begin, visit the Start Project form on Fixie3D.com and upload your 3D/CAD files (STL/OBJ/FBX). Include scale, finish preference (painted/unpainted), delivery date, and address. The team reviews your submission, fixes your files if needed, and provides a quote including printing, finishing, and delivery.

Confidentiality is a top priority. Many clients are architects or developers working on unreleased projects. Fixie 3D routinely signs non-disclosure agreements (NDAs) and ensures all digital files and printed models remain private and secure throughout the project lifecycle.

Their engineers regularly handle BIM-based data (Revit, IFC) and use specialised tools to prepare geometry for physical printing. They repair and simplify complex structures, adjust scale, and generate watertight meshes, ensuring accurate architectural representation.

Fixie 3D occasionally hires designers, model makers, and 3D printing technicians. The Careers page lists openings when available, but speculative applications are always welcome. They value creativity, attention to detail, and experience with CAD or SLA printing.

The Blog section on Fixie3D.com covers topics such as “3D printing for architecture,” “file preparation best practices,” and “environmental efficiency of additive manufacturing.” These articles help architects understand how 3D printing can streamline visualization and reduce waste compared to traditional fabrication.
