Most inventors spend months deciding what their product will look like and minutes deciding what it will be made from. That's a mistake and it's one of the most common reasons products fail, cost too much to make, or disappoint customers.
Your material choice affects almost everything: how strong your product is, how much it weighs, how it can be manufactured, how much it costs, and how it feels in your customer's hands. Get it right, and you've solved a dozen downstream problems at once. Get it wrong, and you may not find out until you're deep into production.
The Maker's Material Guide is a practical, easy-to-read reference that covers every major material family used in physical product development. Each chapter gives you the honest tradeoffs, real-world applications, and clear comparisons you need to make a confident decision without needing a materials science degree.
Keep it on your desk. Come back to it every time you have a material decision to make.
The Maker's Material Guide
8 chapters organized by material family:
- Chapter 1 — A Simple Selection Framework: A six-step process for narrowing down your options and choosing with confidence
- Chapter 2 — Plastics: Detailed breakdowns of ABS, polypropylene, polycarbonate, nylon, PETG, TPU, PEEK, and PLA — with comparison tables and plain-English explanations
- Chapter 3 — Metals: 6061 aluminum, stainless steel, carbon steel, brass, and titanium — strength, machinability, corrosion resistance, and cost compared
- Chapter 4 — Composites: Carbon fiber, fiberglass, Kevlar, and natural fiber composites — when they're worth it and how to access them without a full composite shop
- Chapter 5 — Foams, Rubber, and Elastomers: The right foam for packaging, seating, and sports — plus a rubber comparison table for sealing and flexible applications
- Chapter 6 — Wood, Paper, and Natural Materials: When natural materials outperform synthetic ones and how to design with them
- Chapter 7 — New and Sustainable Materials: Bio-based plastics, recycled content, mycelium composites, and what the sustainability claims actually mean
- Chapter 8 — Material + Process: How to match your material to your manufacturing method — and why getting this combination wrong is so costly
Plus: A full material selection checklist in the Appendix.
