The Complete 28mm Sci-Fi Armor & Proxy Reference Guide

Building a 28mm tabletop army – whether for 10th Edition Warhammer 40K, Horus Heresy, Grimdark Future, or narrative campaign play – frequently involves finding unique vehicle variants, resin alternatives, or thematic proxies to make your force stand out. Not to mention the cost of purchasing official kits! An excellent manufacturing method today is 3D printing. Without the huge demand that the large wargaming companies have it is not feasible to mould the vast selection of 28mm models that buyers need. 3D printing in either FDM or resin gives huge flexibility without sacrificing quality. In fact, many 3D printed proxies are better than the model they replace, with more imaginative designs, tougher denser materials, and easier assembly. The end result is often a premium-feeling weighted vehicle which is impressive on the tabletop.

This comprehensive guide breaks down the top 6 to 8 key vehicles/armour pieces for every major faction, their battlefield roles, and the top independent kit alternatives and proxy prints available across the hobby community.

What to Look For When Buying 3D Printed Proxies

  1. True Scale Compatibility: Ensure models match standard 28mm/32mm heroic dimensions so line-of-sight and base footprints remain accurate for tabletop play.
  2. Armament: The proxy model should carry weapons similar to the original for immersive tabletop gaming and accuracy.
  3. Visual Quality and Surface Detail: Look for suppliers who provide images of actual prints to give assurance of print quality and ensure that the surface detail on the CAD model hasn’t been lost in the printing process.
  4. Resin Quality & Wash Prep: Heavy vehicle hulls require high-impact resin blends to prevent barrel snaps, such as Siraya Tech or similar performance resins. Look for suppliers using multi-stage cleaning processes to eliminate tacky uncured surface resin.
  5. Magnetization Recesses: Models designed with built-in magnet sockets (typically 3mm x 2mm or 5mm x 2mm) make swapping turrets and sponson weapons seamless between game editions.
