The following are three items that are not permitted to be 3D printing from dsfsdf's blog

In classrooms and public libraries, an increasing number of 3D printers are being used, and the cost of these printers is becoming increasingly affordable. University 3D printers are available for students to use in their classes and projects, allowing them to take advantage of this cutting-edge technology. Certified 3D printing applications are available from companies such as MakerBot that cater to both educators and students.

Aside from enabling students to create low-cost rapid prototypes while still in the classroom, 3D printing tools are also revolutionizing STEM education by, among other things, fabricating low-cost high-quality scientific equipment from open hardware designs and fabricating low-cost high-quality scientific equipment from open hardware designs.

Three-dimensional printing ( 3D printing ) was initially developed as a means of producing prototypes in a shorter amount of time. It is estimated that a traditional injection-molded prototype could cost hundreds of thousands of dollars and take weeks to manufacture a single mold, according to the manufacturer. Trying to make incremental improvements to your design with each iteration is completely impractical if you want to make continuous improvements to your design. The use of 3D printing technology has the potential to significantly reduce traditional manufacturing lead times, allowing prototypes to be created in hours rather than weeks, and at a fraction of the cost of traditional manufacturing. The automotive and aerospace industries, to name a few, are among the sectors that have benefited from advancements in 3D Printing Services technology in recent years.

Assistance with MEDICAL EMERGENCY
Patient after patient has reported success with titanium pelvis implants, as well as a titanium lower jaw replacement, among other procedures. It was possible to have the face of a motorcyclist patient who had been severely injured in a road accident rebuilt using 3D printed components after he was severely injured.

Binder Jetting, a 3d printing process that is used to produce pills, can be used to create pills in a controlled environment. Because the pills are extremely porous, high doses of medication can be contained in a single pill that dissolves quickly and is easily digested, making them useful for treating conditions such as epilepsy and other neurological disorders, among others.
