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:
Let’s dive in!
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, 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).
Alumide: Polyamide mixed with aluminum particles, resulting in a stronger, metallic appearance. It can be dyed and polished for added effects.
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.
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:
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 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 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 is one of the most versatile metals for 3D printing, offering excellent strength, corrosion resistance, and a range of finishes:
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.
For creating jewelry or high-end items, precious metals are an excellent choice. You can create parts in materials such as:
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 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 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.
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:
