With 3D printers now available at low cost, manufacturing has become more accessible. In this course, participants learned about 3D modeling and how 3D printers work, and output original 3D printer products conceived by themselves!

In this cutting-edge manufacturing course "Let's Try 3D Printer! In this lecture,
Part I: "What is a 3D Printer?"
Part II: "Challenging 3D Modeling"
Part III: "Let's Output with a 3D Printer"
The event was divided into three parts.

Part I. What is a 3D Printer?
3D printers are devices that print three-dimensional objects using resin, plaster, or metal, as opposed to 2D printers that print two-dimensionally on regular paper. 3D printer patents expired in 2009, which has greatly reduced the price of 3D printers, and now 3D printers are being used not only in the industrial field, but also in the educational field. The use of 3D printers is now spreading not only in the industrial field but also in the educational field!

Part 2: Challenging 3D modeling
As with the designing of a product, a 3D printer requires a design before output. 3D modeling is generally used to draw a design in 3D, and the software used to do this is called CAD.
In this case, we used 123D Design, a free software program that can be used by beginners and advanced users alike.
Even first-time users will be able to draw various blueprints within an hour or two.

Part 3: Let's try outputting with a 3D printer.
By sending the created 3D data to the 3D printer, it is output from the bottom to the top, just like making ice cream.
However, just sending 3D data to a 3D printer does not mean that it will be output. The 3D data is converted into a state in which it is sliced into multiple layers in a PC, and that data is sent to a 3D printer, where it is output one layer at a time from the bottom to the top.

Principle

The 3D printer builds up raw materials from the bottom to the top, just like making ice cream, and then molds the product.

3D modeling challenge

We used 3D modeling software called 123D design to draw the blueprints. This software is easy to use even for beginners and allows for advanced editing.

3D printer output settings

We introduced the settings for sending data created with 3D modeling software to a 3D printer.

Research presentation is an opportunity for growth! This is a research presentation practice game for young researchers! Various schools will gather for mock research presentations and discussions. This is a great opportunity for young researchers to practice their research presentations!
