3D printing started in the 1980s with Charles Hull’s invention of stereolithography (SLA), which used photopolymer resins cured by UV light. Early materials were limited, mostly photopolymers and basic thermoplastics, but the technology has exploded since then.

The Evolution of Materials

  • 1980s-1990s: Photopolymers and simple thermoplastics like ABS dominated.
  • 2000s: Introduction of Fused Deposition Modeling (FDM) popularized PLA and ABS filaments.
  • 2010s: Rise of composite filaments (carbon fiber, wood-filled), flexible filaments (TPU), and metal printing.
  • Today: Hundreds of materials including biocompatible resins, ceramics, and food-safe filaments.

This evolution reflects the growing demand for functional, aesthetic, and specialized prints. As the materials improve, so do the possibilities—from medical implants to architectural models.

Why We Love PLA:
PLA is the go-to filament for beginners and hobbyists. It’s biodegradable, made from renewable resources like corn starch, and prints at relatively low temperatures (180-220°C). It’s perfect for decorative items, prototypes, and educational projects.

Drawbacks:
PLA can be brittle and less heat-resistant, so it’s not ideal for mechanical parts or outdoor use. It also doesn’t dissolve in acetone, making post-processing trickier compared to ABS.

Pro Tip: Use brands like Prusament PLA or Hatchbox PLA for consistent quality. You can find tons of PLA models on Thingiverse.


2. đź’Ş ABS (Acrylonitrile Butadiene Styrene): The Durable Classic

Versatility 8

ABS is the tough, heat-resistant filament favored for functional parts like automotive components and household items. It prints at higher temps (215-250°C) and can be smoothed with acetone vapor for a glossy finish.

Challenges:
ABS requires a heated bed and good ventilation due to fumes. It can warp if cooled too quickly. However, its durability and ability to be glued with ABS slurry (ABS dissolved in acetone) make it a favorite for repair and post-processing.

Our Experience:
We’ve used MatterHackers PRO Series ABS for custom drone parts with great success. For more on finishing ABS prints, check out Make: Magazine’s guide.


3. đź’§ PETG (Polyethylene Terephthalate Glycol): The Best of Both Worlds

Aspect Rating (1-10)

PETG combines the ease of PLA with the strength of ABS. It’s chemical resistant, food-safe (in many cases), and less prone to warping. It prints at 230-250°C and is great for mechanical parts, water bottles, and protective cases.

Why Choose PETG?
If you want a durable, flexible, and easy-to-print filament, PETG is a solid choice. Brands like eSun PETG and Prusament PETG are reliable.


4. ⚙️ Nylon (Polyamide): Strength and Flexibility Combined

Versatility 9

Nylon is a powerhouse material used for gears, hinges, and wearables. It’s strong, flexible, and abrasion-resistant but requires high printing temps (240-270°C) and low moisture environment.

Our Tip: Store nylon filaments in airtight containers with desiccants. Taulman3D Nylon 645 is a popular choice.


5. 🤸 TPU (Thermoplastic Polyurethane) & Other Flexible Filaments: Bend It Like Beckham!

Aspect Rating (1-10)

Metal 3D printing (DMLS, SLS) is used in aerospace, medical implants, and automotive industries. Materials include titanium, stainless steel, and aluminum.

Note: Metal printing requires industrial-grade machines and is costly but offers unmatched strength and heat resistance.


8. 🌿 Composites (Carbon Fiber, Glass Fiber, Wood, etc.): Enhanced Performance

Composite filaments blend base plastics with fibers or particles to improve strength, stiffness, or aesthetics.

Composite Type Base Material Benefits Drawbacks
Carbon Fiber Nylon, PLA High strength, stiffness Abrasive on nozzles, costly
Wood-Filled PLA Wood-like finish, aesthetic Brittle, less durable
Glass Fiber Nylon, PETG Improved strength Abrasive, requires hardened nozzle

Our Favorite: ColorFabb XT-CF20 (carbon fiber nylon) for drone frames.

What are the most common materials used in 3D printing for beginners?

For beginners, PLA (Polylactic Acid) is the most popular choice. It’s easy to print with, requires no heated bed (though it helps), and is environmentally friendly since it’s biodegradable. PLA prints with minimal warping and emits a sweet smell rather than harsh fumes. It’s ideal for prototypes, toys, and decorative objects.

ABS is another common filament but is better suited for users with some experience due to its higher printing temperature and warping tendencies. PETG is gaining popularity as a beginner-friendly alternative with better durability than PLA.

What are the differences between PLA and ABS filament in 3D printing?

PLA is derived from renewable resources like corn starch, making it biodegradable and eco-friendly. It prints at lower temperatures (180-220°C), has minimal warping, and is great for detailed prints. However, PLA is more brittle and less heat-resistant, so it’s not ideal for functional parts exposed to stress or heat.

ABS is petroleum-based, stronger, and more heat-resistant, making it suitable for mechanical parts and functional prototypes. It prints at higher temperatures (215-250°C), requires a heated bed, and emits fumes that necessitate good ventilation. ABS can be smoothed with acetone vapor, which PLA cannot.

How do I choose the right 3D printing material for my project?

Choosing the right material depends on several factors:

  • Purpose: Decorative vs. functional parts.
  • Strength & Flexibility: Does your part need to bend or bear weight?
  • Printer Compatibility: Some materials require specific printer features (heated bed, enclosure).
  • Post-Processing: Are you willing to sand, acetone-smooth, or cure your prints?
  • Environmental Concerns: Do you prefer biodegradable materials?
  • Budget: Some specialty filaments and resins cost more.

Start with PLA for simple projects, then explore PETG or ABS for durability, Nylon for strength, TPU for flexibility, and resin for detail.
