The second question is: "What's next?" There are a few things we can improve for making 3D printers standard equipment for laboratory use: A proper database is still missing. So far, designs are shared on different databases, which renders the search for a particular design cumbersome. NIH made a 3D printed parts database some years ago, but many researchers prefer to use other ones. It is not well maintained, and the search for parts is almost in-existent. To solve this problem, a unified database with a good search engine and a DOI or DOI-like system to properly cite the design is desired. Another important thing is to teach about 3D printing and 3D design. Basic principles of 3D printing, 3D design, and programming should be in the curriculum of practically any scientist. And here, my suggestion to you is to introduce, even if for less than an hour, 3D printing in your course, regardless of what you teach. The new technology will heavily influence the future generation of scientists and introducing 3D printing and programming as soon as possible in their curricula will be of great help for students' development.
