Choosing the right 3D printing material is just as important as choosing the right printer. Every project — whether it’s a toy, tool, prototype, or wearable — has different needs. In this guide, we’ll walk you through the factors to consider and help you pick the perfect filament or resin for your next print.
🧠 Start with These 3 Questions:
- What is the purpose of your print?
- Display or functional use?
- Will it hold weight, bend, or take stress?
- Where will it be used?
- Indoors or outdoors?
- Near heat, chemicals, or water?
- How much detail or surface finish do you need?
- Smooth and polished or rough and durable?

📦 Don’t Forget Practical Things:
- 🔥 Does your printer have a heated bed? (needed for ABS, PETG)
- 🧽 Do you have post-processing tools? (needed for resin prints)
- 🌬️ Is your space well-ventilated? (for ABS, resin)
- 💰 What’s your budget? (Resin & specialty filaments cost more)
💡 Pro Tips:
- Start with PLA if you’re unsure — it’s reliable, cheap, and easy
- Use PETG if you want strength + moisture resistance
- Go for TPU only if you’re comfortable with advanced settings
- Choose resin only if detail is your top priority and you can post-process safely
