Print N Scale Building: A DIY Guide

Shrink Your Dreams: The Ultimate DIY Guide to Building to the Nth Level

The world of model railroading thrives on meticulous detail and transports viewers into a world of miniatures. At the heart of any charming layout are the structures: houses, stations, factories and barns that bring the scene to life. For fans of N scale (usually 1:160 scale), space efficiency is key, making DIY construction extremely attractive. This guide delves into the exciting possibilities of creating your own N-scale structures, exploring techniques, materials, and how advances like precision 3D printing are revolutionizing the hobby.

Why DIY N-scale buildings?

• Unparalleled Customization: Get rid of the constraints of commercially available kits. Design the precise buildings your layout requires – a unique factory, a farmhouse in a specific area, or a row of shops that reflects your favorite street.
• Cost efficiency: While there are start-up costs for tools or printing, making multiple buildings yourself, especially simpler designs, can be much cheaper than buying a kit.
• Creative realization: There is great satisfaction in seeing a structure emerge from your own planning and efforts.
• Scalability and consistency: Need ten identical workers’ huts? DIY can be replicated exactly.
• The joy of problem solving: Meeting the challenges of miniaturization is inherently rewarding for hobbyists.

Basic DIY approach to N-scale construction:

1. Traditional staging build:

   • Material: Card stock, foam core board, balsa wood, styrene board/rod, basswood strips, craft sticks, wood glue, plastic cement, CA glue.
   • process: It requires careful measuring, cutting, assembling and perfecting.
   • advantage: The barriers to entry are very low (basic tools like knives, rulers). Great for block building or learning the basics.
   • shortcoming: Time intensive. Achieving intricate detail and consistency at N scale (especially windows, doors, textures) is challenging. Durability can be an issue with lighter materials.
   • Scale fidelity tips: Use printed paper overlays to apply bricks, siding, or roof tiles to cardstock walls for an enhanced sense of realism.

2. Kit bashing:

   • concept: Modify and combine parts from existing business model kits (plastic or card) to create something new.
   • advantage: Faster than building from raw materials. Make use of existing details like windows or doors. Great for experimentation.
   • shortcoming: Subject to pose and style of donor kit. Cutting, modifying and finishing skills are still required. Increased costs.

3. 3D printing (the game changer):

   • Material: Mainly photopolymer resin (for SLA/DLP/LCD printers) or PLA/ABS/PETG filament (for FDM printers).
   • advantage: Unleash incredible precision and complexity at N scale. Excellent reproduction of fine textures (wood grain, brick, stone), gorgeous details and perfectly reproduced parts. Files are easy to expand and modify. Ideal for intricate details such as stairs, railings, tiny signage and more. STL files can be easily shared or purchased online.
   • shortcoming: Requires access to printer (owned or outsourced). There is a learning curve involved with printing/cleaning/finishing. Resin handling requires safety precautions.
   • Printing nuances: N Scale details:

     • Resin printing (SLA/DLP/LCD) It is the first choice for most people. Layer heights of 0.025mm – 0.05mm allow for stunning smoothness. Use high-resolution, fast-curing resin designed for microscopic features.
     • FDM printing: Yes, but requires perfect calibration, tiny nozzles (0.2 mm or less) and very fine layer heights (<= 0.08 mm). Best used for larger, less complex buildings or terrain features where layer lines are less obvious. Slow printing speed is critical.
     • Post-processing: Water-washable resin simplifies the cleaning process. Use a mild IPA bath for others. Carefully remove the supports. Flat surfaces may require sanding – use a high grit wet sander (>600 grit). Primer (acrylic spray) is essential for an even painted surface.

Design your N-scale masterpiece:

• Reference photos: Collect high-quality images of prototype buildings for accurate scale, detail, and weathering.
• planning: Draw plans, decide on construction methods, list materials/parts. Break down complex buildings into modules (walls, roofs, removable parts).
• software:

  • Simple: Inkscape (2D patterns), Tinkercad (basic 3D).
  • Advanced: SketchUp, Fusion 360, Blender (complex modeling). Focus on solid modeling techniques necessary for printing waterproof meshes.

Detail and paint for maximum impact:

• Surface preparation: Filling gaps/sanding (especially FDM). Prime thoroughly. For card/wood, seal the surface before painting.
• painting: Acrylic paint is ideal. Airbrushes provide the smoothest results. Use washes (diluted dark paint) to emphasize details. Dry brush lightly to raise texture.
• weathering: Essential to realism. A subtle clean of dirt and a crayon/dry paint clean of rust/dirt streaks. Avoid overdoing it on the N scale.
• Windows: Transparent acrylic plate painted frame or 3D printed insert. Mirrored plastic creates the illusion of depth. Glass gloss adds realism.
• Signage and Advertising: High resolution inkjet prints scaled down. Apply decals effectively.
