Materials Overview 

Materials form the backbone of 3D printing technology. Without a compatible material for a specific application, 3D printing technology can never be adopted by any industry. Sensing this basic premise early on, engineers, researchers, and scientists have embarked on a journey to develop and qualify widely used traditional materials for 3D printing. This approach has resulted in growing the 3D printing materials library.

Today, we have a wide range of materials available for 3D printing. Right from polymers to metals and from sand to food. All these materials have specific applications and serve a core purpose to efficiently and sustainably build products.

Through this materials guide, we list down the popular materials available for 3D printing.


Polymer materials originated with the birth of 3D printing. The first-ever technology to be invented and commercialized was Stereolithography and it operated on a liquid polymer material (Resins). So this was also the first material to be developed and qualified for 3D printing. 

There are however two types of polymers that are popular in 3D printing and they are also used in different forms for different technologies. We take an in-depth look at the polymer materials available for 3D printing.

Polymer Filaments

Polymer filaments are hands-down the most popular form of 3D printing materials. These filaments are used in Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF) technology. 

The polymer filaments are formed from thermoplastic polymers. These are polymers that can be heated and cooled multiple times without much change in their chemical composition or mechanical properties. Since they can be alternatively heated and cooled, they can be reused.

Polymer filaments are formed through an extrusion process where plastic granules are melted and extruded into a filament form. This filament is then wound around a spool to form the material for FDM/FFF technology. 

Popular Polymer Filaments

Polylactic Acid (PLA) 

Polylactic Acid or PLA is the most common material available for 3D printing. It is made from corn starch and is biodegradable. It is also a food-safe material however the food safety also depends on the PLA blend and the 3D printer used as the printer components can contaminate the material. So, care should be taken when printing the material for a food application. 

PLA is an inexpensive material and is widely available all around the globe. It is

Acrylonitrile Butadiene Styrene (ABS)

Acrylonitrile Butadiene Styrene or ABS is also a well-known and widely used FDM 3D printing material. It exhibits good heat, impact, and chemical resistance and so it is used as an industrial-grade material. Since ABS is also popularly used in traditional manufacturing, the material has numerous applications in 3D printing as well. 

ABS is easy to machine and can also be smoothened with acetone vaporing. This helps it in gifting applications. However, ABS releases toxic fumes while 3D printing and so it should always be 3D printed in a well-ventilated room. ABS is also plagued with issues like warping and cracking and it is a difficult material to print with. With appropriate settings, the issues can be resolved.

Nylon is a tricky material to 3D print due to various reasons. It has a higher melting point, it is hygroscopic which means they absorb moisture from the surroundings. This property can affect the printing quality of the material. The moisture can cause air pockets in the material while printing and so can affect the print and its performance.

Nylon Print Settings
  • Printing Temperature: 240oC to 260oC
  • Bed Temperature: 70oC to 90oC
  • Heated Bed: Required
  • Enclosure: Recommended

Refractory Metal

Tungsten W1 

Tungsten is known for its hardness, highest melting temperature of all metals at 3,422 °C. This makes it an ideal material for high-performance industries ranging from aerospace and medical to defense, and nuclear.

However, the hardness and also makes it difficult to process through traditional manufacturing techniques. 3D printing plays a big role in leveraging the materials’ advantages. 

With tungsten, very thin yet strong walls can be manufactured enabling lesser use of material while maintaining the strength. 

Precious Metals

Precious metals are used for a wide range of applications in the jewelry and watch industries but also in dental, electronics, and other industries.

Precious metals like Gold, Silver, Platinum, and Palladium can also be efficiently 3D printed in metal additive manufacturing systems.


3D printing in the construction industry is fairly new. It is however a highly lucrative and fast-growing market. Right now, 3D printing technology has only touched the surface of this industry as it faces challenges on multiple fronts. Right from 3D printers, the process, and the materials, companies are racing against time to get the entire process standardized. 

One of the crucial elements of construction3D printing is its material. Traditionally used concrete material cannot be directly used for 3D printing and so companies are developing their materials compatible with their vision, processes, and products. 

Most of the concrete materials for 3D printing consist of cement concrete mixed with sand and additives. Some companies also add fibers to this mixture to increase the strength further.

Considering the potential of 3D printing and the sustainability approach it promotes, companies are also exploring earth-based materials to eliminate the carcinogenic issues related to cement. WASP, a construction 3D printer manufacturer, developed an earth-based compound composed of 25% of soil taken from the site (30% clay, 40% silt, and 30% sand), 40% from straw chopped rice, 25% rice husk, and 10% hydraulic lime. This material was used to build the ‘Gaia House, a 3D-printed house made from the abovementioned earth-based material. The company claims that this material has an almost zero environmental impact.

Bioinks (200)

Bioinks are materials used by bioprinters to build biostructures that have applications inside a living organism. Bioinks contain living cells and biocompatible materials that mimic the extracellular matrix environment, supporting cell adhesion, proliferation, and differentiation after printing. 

Though a variety of materials are used for manufacturing bioinks the most popular ones are collagen, Alginate, poly(ethylene glycol) (PEG), gelatin methacryloyl (GelMA), Pluronic®, and decellularized extracellular matrix (ECM)-based materials.

Cellink Bioink

Cellink, the world’s First Bioink Company, and has developed a non-animal derived polysaccharide hydrogel that is ideal for 3D bioprinting and cell culturing. This patented bioink is composed of alginate and highly hydrated cellulose nanofibrils with morphological similarity to collagen, providing mammalian cells with a milieu that resembles their natural matrix.

The uniqueness of these hydrogel products has been recognized quickly on the market since they are unique in chemical and physical tunability. These features allow the products to replicate the characteristics of specific tissues so that the cells experience and engage with a realistic 3D environment. Building on the success of Biogelx core technology, the company has also designed a novel bioink product family. 


Composite materials are typically core polymer materials mixed with a reinforcing material like chopped or continuous fiber. The polymer base helps in ease of printing while the fibers impart higher strength and stiffness compared to non-reinforced polymers. Composites are also lightweight with better strength than polymers. In some cases, the composites can also replace metals. 

The strength properties of composites make them ideal for applications in the aerospace, automotive, tooling, industrial, maritime, and oil and gas industries.

It is possible to 3D print with two types of fibers: Chopped and Continuous. While chopped can be 3D printed through extrusion-based technologies, continuous fibers require a separate and dedicated technology.

Popular Composite Materials

Carbon Fiber

Carbon fiber is the most famous composite material made from a polymer material like PLA or PETG mixed with chopped fibers. Carbon Fiber can also be embedded in Nylon, PEEK, and PEKK. This type of composite can be 3D printed in FDM or other extrusion-based 3D printers (like those offered by Desktop Metal and Markforged). 

Carbon-reinforced PESU material

Polyethersulfone or PESU is a unique thermoplastic material known for its high performance. It is an amorphous material with very high heat resistance, it is food safe and exhibits good electrical insulation and dielectric properties. Due to its high heat resistance, it is a desirable material in the aerospace, rail, and automotive industries. It is even better than the Ultem brand of industrial-grade materials and it is cheaper than them.

A carbon-reinforced PESU offers significantly greater properties than a regular PESU, which is already a super-material.

Diamond Composite

Sandvik, the Swedish multinational engineering company, developed a diamond composite material to target the industries desiring a large range of wear-resistant tools. Traditional manufacturing of diamond-based tools is difficult to process and therefore they cannot be machined into required shapes. The diamond composite aims to solve this critical challenge. 

The diamond composite super-hard material now can be printed in highly complex shapes giving access to better tools for mining, cutting, and other relevant industries. 


Food was mostly an experimental material early on but it has quickly evolved into a crucial material that aims to reduce food wastage. Moreover, food 3D printing also includes areas such as 3D printed meat and fish. This is a whole new area of interest with numerous Startups focusing on developing animal and plant-cell-based meat to solve the global problems of the meat industry. 

Generic Food

The food experimentation started with replacing the filament extruder in FDM 3D printers with a syringe extruder. The syringe housed a food paste generally a chocolate paste or a pancake paste and this was deposited onto a build platform. Though most of these materials cannot create completely three-dimensional objects (except chocolate) they are surely able to 3D print with food. 

Meat 3D printing 

Meat 3D printing closely resembles bioprinting where cells are cultivated to form the alternative meat. The alt-meat is derived either from animal sources (without harming the animals) or plant sources (can be called vegetarian meat).
