3D printers can print anything, but what 3D printing materials can be used is a question.https://www.esun3d.com/

What is the material of the 3D printer?
What are 3D printer materials? It's a bit like 2D printer ink. A 3D object is formed by layering and solidifying 3D printing materials.
3D printers can use a variety of materials, but there are different types of 3D printer materials that can be used with each printing method.

In the Fused Deposition Modeling (FDM) method, a material called a filament is used.3D printer filament is a long, thin strand of meltable resin.

In the case of stereolithography (SLA method/DLP method) or inkjet method (material injection method), 3d printer resin cured by ultraviolet rays is used.

In the case of the powder sintering method (SLS method) or the binder jetting method, powder materials are used. do it. In addition to resin, various powder materials such as metal powder and gypsum can be used.

According to your printer type and printing method, choose the appropriate 3D printing materials.
