Three-dimensional (abbreviation for three dimension)
Comments on lectures on printing technology
I attended a lecture last Saturday.
Three-dimensional (abbreviation for three dimension)
Lecture on printing technology. Through the study of this lecture, let
I have learned a lot, and I feel a lot. Now I will briefly introduce it.
Three-dimensional (abbreviation for three dimension)
Printing technology.
Three-dimensional (abbreviation for three dimension)
Printing technology is three-dimensional printing (English:
3D printing
)
, which is rapid prototyping.
A technology, it is a kind of
Based on digital model files, powder metal or plastic is used.
The adhesive material is printed layer by layer.
The technology of building objects. In the past, it was once a model.
Tool manufacturing, industrial design and other fields have been used to manufacture models, and now they are gradually used in one.
Some products
Direct manufacturing. Especially for some high-value applications (such as hip joints or teeth, or some airplanes).
Parts)
Parts already printed with this technology.
"Three-dimensional printing" means

A few applications are enough (in curved products).
You can use the following methods: first, print a little new life with the current three-dimensional printer.
Point the object, and then
After a little surface polishing, you can get a "high resolution" article with a smooth surface.
