What is the strongest material you can 3D print?
Engineer (Prime): You’re thinking about structural 3D prints?
Buyer: Exactly. I want to know—what is the strongest material you can 3D print?
Engineer: That’s a great question. It depends on whether we’re talking plastic or metal. For plastics, reinforced polymers lead the way. For metals, titanium and Inconel are among the strongest printable options.

What is the toughest material for 3D printing?
Buyer: So, what’s the toughest material available in filament form?
Engineer: For plastic-based 3D printing, the toughest printable material is usually carbon-fiber reinforced nylon or PEEK.
| Material | Tensile Strength (MPa) | Heat Resistance (°C) | Notes |
|---|---|---|---|
| Carbon-fiber Nylon | 80–120 | 100–150 | Strong, stiff, machinable |
| PEEK | 90–100 | 250+ | High-temp, aerospace-grade |
| Polycarbonate (PC) | 55–70 | 110–130 | Tough but requires high heat |
| ASA | 45–50 | 95–100 | UV-stable, weather-resistant |
Buyer: I’ve seen PEEK before, but it's expensive.
Engineer: True—and difficult to print. That’s why many clients at Prime choose carbon-fiber nylon for strength, price, and reliability.
Is PETG or PLA stronger?
Buyer: Between PLA and PETG—which is better for strength?
Engineer: PETG is stronger and more flexible. PLA is stiffer but brittle. PETG is better for functional parts.
| Feature | PLA | PETG |
|---|---|---|
| Strength | Moderate | Higher |
| Flexibility | Low (brittle) | Medium (ductile) |
| Temperature | 55–65°C | 75–85°C |
| Ease of Print | Very Easy | Easy |
Summary: For strong, durable prints, PETG wins over PLA in most engineering applications.
Is ASA or PC stronger?
Buyer: I’ve used ASA for outdoor parts. Is PC stronger?
Engineer: Yes—polycarbonate (PC) is stronger and more impact-resistant than ASA.
However, ASA is more UV and weather-resistant, making it great for outdoor enclosures or signage.
| Property | ASA | Polycarbonate (PC) |
|---|---|---|
| Tensile Strength | 45–50 MPa | 55–70 MPa |
| UV Resistance | Excellent | Moderate |
| Impact Toughness | Medium | Very High |
| Print Difficulty | Medium | High (needs heat) |
Buyer: So for a strong indoor bracket—PC. For a weatherproof box—ASA?
Engineer: Exactly. And if you want strength + UV resistance, we can also blend modifiers or coat parts after printing.
What is the strongest metal that can be 3D-printed?
Buyer: Now let’s talk metals. What is the strongest metal that can be 3D-printed?
Engineer: It depends on what you mean by “strongest”—tensile strength, hardness, or fatigue resistance. But overall:
Titanium (Ti-6Al-4V) and Inconel 718 are two of the top contenders.
| Metal | Strength (MPa) | Temperature Resistance | Application Areas |
|---|---|---|---|
| Titanium Ti64 | 900–1150 | 400–600°C | Aerospace, medical, racing |
| Inconel 718 | 1000–1300 | 700–800°C | Jet engines, turbines |
| Stainless Steel | 600–1000 | 300–500°C | Tooling, general-purpose parts |
| Aluminum AlSi10Mg | 320–400 | 200–250°C | Lightweight prototypes, housings |
Buyer: That’s impressive. And you offer all of these at Prime?
Engineer: Yes. We partner with certified facilities for metal SLM printing, and help clients choose the right material for strength, cost, and geometry.
Frequently Asked Questions (FAQ)
❓ What’s the strongest plastic you can print on a desktop printer?
Engineer: Carbon fiber reinforced nylon is the best mix of strength, stiffness, and printability.
❓ Can you 3D print steel?
Engineer: Yes. 316L and 17-4PH stainless steel are widely used in DMLS and binder jetting.
❓ Is PEEK stronger than carbon fiber nylon?
Engineer: It depends. PEEK is better at high temperatures and chemicals, but carbon fiber nylon is stiffer at room temp.
❓ Is titanium stronger than stainless steel?
Engineer: Yes. It’s stronger per weight, and more corrosion resistant—ideal for critical aerospace or biomedical parts.
Conclusion
Buyer: So, what is the strongest material you can 3D print?
Engineer: For plastics—carbon fiber nylon. For metals—titanium or Inconel, depending on your application.
Buyer: That gives me a solid starting point. I’ll reach out when I’m ready for a quote.
Engineer: Great. We’ll help you optimize for strength, weight, and price.
