Choosing the best 3D printing materials is one of the most important decisions in any 3D printing project. The right material affects strength, durability, heat resistance, surface finish, and long-term performance. Whether you are printing functional parts, miniatures, car components, or moulds, understanding what is the best material for 3D printing can save time, cost, and rework.
This guide explains the best 3D print material based on real-world use cases, helping you select the best material to 3D print with for your application.
What is 3D Printing Material?
3D printing materials refers to the filament or different types of resin used by a 3D printer to create physical objects layer by layer. There is no single material that is best for all projects, as the best 3D printing material depends on factors such as mechanical strength, heat resistance, outdoor durability, flexibility, surface detail, and the final application.
Materials like PLA, PETG, ABS, Nylon, TPU, and high-performance options such as carbon fiber–filled filaments are used for different purposes, ranging from decorative models to strong, functional parts.
Best 3D Printing Material for Strength & Durability
When strength is the priority, material choice becomes critical.
Nylon (PA)
Nylon is considered the best 3D printing material for strength and durability. It offers excellent impact resistance, wear resistance, and flexibility without breaking.
Best used for:
Strong handles
Mechanical parts
Gears and brackets
Functional prototypes
Nylon is also one of the best materials for 3D printed gears due to its low friction and toughness.
Carbon Fiber Reinforced Filaments
Carbon fiber-filled Nylon or PETG provides exceptional stiffness and strength-to-weight ratio.
Best used for:
Structural brackets
Load-bearing components
Automotive and industrial parts
This is often considered the best material for 3D printing car parts where rigidity is required.
Best 3D Printing Material for Heat Resistance
If your part will be exposed to high temperatures, standard filaments like PLA are not suitable.
ABS
ABS is a popular heat resistant 3D printing material that performs well in warm environments.
Best used for:
Automotive interior parts
Housings
Enclosures
Polycarbonate (PC)
Polycarbonate is the best 3D printing material for heat resistance among commonly available filaments.
Best used for:
High-temperature components
Mechanical and electrical housings
It is often considered the best material for 3D printing high temperature applications.
Best 3D Print Material for Outdoor Use
Outdoor parts must withstand UV exposure, moisture, and temperature changes.
PETG
PETG is widely regarded as the best 3D print material for outdoor use.
Why PETG works outdoors:
UV resistant
Moisture resistant
Stronger than PLA
ASA
ASA is an advanced alternative to ABS and is often the best 3D printing material for outdoor durability.
Best used for:
Outdoor brackets
Automotive exterior parts
Long-term outdoor applications
Best Material for 3D Printing Gears
Gears require strength, wear resistance, and smooth motion.
Best materials to 3D print gears:
Nylon (PA)
Nylon with carbon fiber
PETG (for light-duty gears)
Nylon remains the best material to 3D print gears for mechanical reliability.
Best 3D Printing Material for Miniatures & Board Games
When printing miniatures and board game components, surface detail, sharp edges, and smooth finish are far more important than extreme strength. The material must be easy to print, capable of capturing fine details, and suitable for post-processing such as sanding and painting.
PLA is widely considered the best 3D printing material for miniatures because it prints at lower temperatures, produces minimal warping, and delivers excellent detail accuracy. It is ideal for creating small, intricate models with clean surfaces.
Best used for:
Board game pieces
Miniatures and tabletop models
Figurines and decorative parts
For hobbyists and designers, PLA remains the best material for 3D printing miniatures and board games, offering reliable results, fine detail reproduction, and an easy workflow for finishing and painting.
Best 3D Print Material for Cosplay
Cosplay parts require a balance of strength, weight, and finish.
Best materials for cosplay:
PETG is commonly considered the best 3D print material for cosplay when durability is needed.
Best 3D Printing Material for Moulds & Casting
For mould-making applications, material must withstand pressure and sometimes heat.
Best materials for 3D printed moulds:
PETG
Nylon
These are commonly used as the best 3D printing material for moulds and resin casting workflows.
Best Way to Remove Support Material in 3D Printing
The best way to remove support material from a 3D print depends on the filament used.
PLA & PETG: Use pliers and light sanding
ABS: Controlled snapping and post-processing
Soluble supports (PVA): Dissolve in water
Proper support settings also help separate raft materials cleanly without damaging the print.
FAQs
What is the best 3D printing material for beginners?
For beginners, PLA is considered the best 3D printing material due to its ease of use, low printing temperature, and minimal warping. It does not require an enclosed printer and delivers consistent results, making it ideal for learning, hobby projects, and decorative models. PLA is also widely available and affordable, which makes it beginner-friendly.
What is the best 3D printing material for outdoor use?
The best 3D printing material for outdoor use is PETG or ASA, as both offer good resistance to UV rays, moisture, and temperature changes. PETG is easier to print and suitable for most outdoor applications, while ASA provides superior weather resistance for long-term outdoor exposure. PLA is not recommended for outdoor use due to heat sensitivity.
Which is the best 3D printing material for strength and durability?
For strength and durability, Nylon and Carbon Fiber reinforced filaments are among the best options. These materials offer high impact resistance, flexibility, and excellent mechanical performance, making them suitable for functional parts, gears, brackets, and load-bearing components. They are commonly used in industrial and engineering applications.
What is the best 3D printing material for heat resistance?
The best heat resistant 3D printing materials include ABS and Polycarbonate (PC). ABS performs well in moderately high-temperature environments, while Polycarbonate offers superior heat resistance and mechanical strength. These materials are ideal for enclosures, automotive components, and parts exposed to elevated temperatures.
The best 3D printing materials depend entirely on the intended application, as no single material fits every use case. For strength and functional parts like gears, Nylon and Carbon Fiber Nylon offer excellent durability, while PETG and ASA are ideal for outdoor use due to their weather resistance. When heat resistance is required, ABS and Polycarbonate perform best, whereas PLA remains the top choice for miniatures because of its fine detail and ease of printing.
