3D Printing Materials Guide: 100+ Options to Choose From for Every Project

09.11.2024 | 3dprintal

With the vast range of 3D printing materials available today, choosing the right one for your project can be overwhelming. Whether you’re a designer, engineer, or hobbyist, it’s important to understand the various materials and finishes that can bring your creations to life. In this blog post, we’ll take you through the most popular 3D printing materials, their key features, and the finishes available for each, making it easier for you to pick the perfect material for your next project.

We’ve broken this guide down into three main categories:

  1. Plastic 3D Printing Materials
  2. Metal 3D Printing Materials
  3. 3D Printing with Other Materials

Let’s dive in!


Plastic 3D Printing Materials

Plastic is the most commonly used material for 3D printing, and for good reason. It’s versatile, easy to work with, and comes in a variety of finishes. Here are some of the most popular plastic materials:

Polyamide (Nylon)

Polyamide, often referred to as Nylon, is a strong and flexible plastic, commonly used for 3D printing. It comes in two main versions: SLS (Selective Laser Sintering) and MJF (Multi Jet Fusion).

  • Natural Polyamide (SLS and MJF): Both options have a rough, matte finish and are ideal for functional prototypes and parts that require strength and flexibility.
  • Dyed Polyamide: Polyamide can be dyed in a wide range of colors to match specific design needs.
  • Polished Polyamide: A smoother finish with a shiny appearance, ideal for parts that need a more refined look.

Alumide: Polyamide mixed with aluminum particles, resulting in a stronger, metallic appearance. It can be dyed and polished for added effects.

Polypropylene

Polypropylene is a highly flexible plastic often used for functional and durable parts. It has a translucent off-white color with a slightly sandy texture, making it perfect for parts that require a tough, yet flexible material.

Resins

Resin 3D prints are made from liquid photopolymer, hardened by UV light during the printing process. Resin offers fine detail and a smooth surface. Here are some resin options:

  • Gray Resin: Offers a smooth surface with a natural finish and can be spray painted in various colors.
  • High-Detail Resin: Offers an extremely high level of detail for prints that require intricate designs.
  • Mammoth Resin: Ideal for larger-scale prints, available in both natural and spray-painted finishes.
  • Transparent Resin: Perfect for clear, glass-like objects that require high clarity.
  • Standard Resin: A versatile option with basic finishes and the option to remove support marks for a cleaner look.

ABS (Acrylonitrile Butadiene Styrene)

ABS is a strong plastic with properties similar to injection-molded parts. It’s tough, durable, and commonly used for prototyping, functional parts, and toys. It can have a rough surface finish compared to other materials.


Metal 3D Printing Materials

Metal 3D printing is used for creating strong, functional parts, often in industries like aerospace, automotive, and medical devices. All metal prints are made from powdered metal, fused together using laser sintering or binding agents. Here are some key metal options:

Aluminum

Aluminum is lightweight and strong, ideal for parts that need to be both durable and lightweight. Its natural finish has a slight sparkle due to silicon content.

Stainless Steel

Stainless steel is one of the most versatile metals for 3D printing, offering excellent strength, corrosion resistance, and a range of finishes:

  • High-Detail Stainless Steel: Offers fine details and a matte, satin, or glossy finish for polished, aesthetic prints.
  • Steel: Available in various finishes, including polished, unpolished, and gold-plated options for a more premium look.

Titanium

Titanium is the strongest 3D printing metal, known for its toughness and light weight. It’s often used for high-performance applications such as aerospace and medical devices. Titanium prints have a matte finish and can be further polished or treated for different effects.

Precious Metals (Gold, Silver, Copper, Brass, Bronze)

For creating jewelry or high-end items, precious metals are an excellent choice. You can create parts in materials such as:

  • Gold: Available in 14K and 18K yellow, red, or white gold.
  • Silver: Available in five finishes, including gloss, satin, antique, and sandblasted.
  • Copper and Brass: These metals come in natural, polished, and plated finishes for a luxurious look.

3D Printing with Other Materials

Some specialized 3D printing materials offer unique properties that can’t be categorized into traditional plastics or metals. Here are a few of the most interesting options:

Multicolor

Multicolor printing allows you to print models in multiple colors, ideal for designs that need to stand out. The material is made of fine, white granular sandstone powder, with the exterior of the model being "painted" with color during the printing process.

Rubber-like Materials

Rubber-like materials are highly flexible and offer a soft, textured surface. These materials are often used for parts that require elasticity and flexibility, such as gaskets, seals, or even soft toys. The material is printed using Multi Jet Fusion technology and comes in various finishes, including natural, dyed, and extra smooth.


Choosing the Right Material for Your 3D Print

With so many materials and finishes to choose from, selecting the right one for your project can be a challenge. Here’s a quick breakdown to help you decide:

  • For strength and durability: Choose Polyamide (Nylon) or ABS for functional prototypes and parts that need to withstand wear and tear.
  • For fine detail and smooth finishes: Opt for Resins like High-Detail Resin or Mammoth Resin for intricate designs or models that need a high-quality surface finish.
  • For lightweight parts: Aluminum or Titanium are perfect for parts that need to be both strong and lightweight, such as aerospace components.
  • For flexibility: If you need rubber-like properties, choose Rubber-like material for soft and flexible parts.
  • For decorative or jewelry items: Use Precious Metals like Gold, Silver, or Brass for a luxurious, high-end finish.
