How to create a 3D scale model is a question that I have often asked myself, as I am pretty good at creating my own dollhouse furniture, for example, but for other things like figurines, I really have no idea so far.
Of course, there is so much more to talk about this topic of how to create 3D scale models than just figurines, so today we are going to dive into the world of a 3D scale model room box, furniture, plants, and more!
How Do You Make A 3D scale Model Step By Step? (based on a course by a 3D scale model maker)
(This tutorial is based on the online course by Julieta La Valle, a 3D scale model maker and her tutorial is available throughout this blog post)
1. Collect The Materials That You Need
Here's a list of the materials that you need to craft 3D models:
- A cutter
- A crafting knife
- Scissors
- a metal ruler
- a triangular ruler aka Architectural Scale Ruler
- a drawing triangle
- a tape measure
- pencil and rubber to draw the plans

These are the basics, but there's more:
- Different kinds of glues: glue for fabrics and polystyrene, multi-purpose glue for wood or cardboard, fast-grabbing glue like tacky glue.
- Optional: adhesive spray glue
- Paper tape (two-sided)
- Optional: spray paint (primer spray can be useful)
- acrylic paint
- paintbrushes or a paint roller for the walls
- varnish
- colored pencils for the miniature plants
- architect paper (foamed PVC)/wood (MDF)/cardboard, depending on what kind of material you want to work with
- wood veneer sheets
- Paper green sheets for the plants
- polycarbonate sheets ( thermoplastic polymers) for the windows
- sandpaper
- wooden rods
- fabrics

2. Learn About The Scales
First, I have written before about the different scales in the miniature world.
But how to calculate everything that you want to make in miniature size, is another thing to learn.
Here's where the architectural scale ruler comes in handy!
- measure any object around you that you want to scale, like a table, with a measuring tape
- Draw the measurements of the table or other object on paper with a quick sketch
