Yangzhou baoying focuses on 3D printing technology training for teachers
In order to effectively improve the application level and practical ability of 3D printing technology for teachers in middle and universities, WEEDO is assisting teachers in baoying, yangzhou to study 3D printing technology during the summer vacation. This training mainly showed the teachers 3D printing technology and how to quickly apply 3D printing technology in teaching to promote the development of maker education.
– Practical courses–
In the practice course, the teacher explained 3d design modeling printing in detail to the students. The so-called 3d modeling is to use 3d data to reconstruct 3d objects in the real world in the computer, and finally achieve the simulation of real 3d objects in the computer. 3d data is to record the physical parameters of finite surface bodies at discrete points. There are three methods commonly used in 3d modeling:
1. 3d software modeling:
Excellent modeling software, such as 3D MAX, can use basic geometric elements to build complex models through translation, stretching, rotation, Boolean operation and other operations.
2. Instrument and equipment modeling:
Three-dimensional scanner can obtain three-dimensional spatial coordinates of each sampling point on the object surface by scanning, and it does not output a two-dimensional image, but a digital model file containing three-dimensional spatial coordinates and colors of each sampling point on the object surface.
3. Model according to images or video:
IBMR technology is used in image-based modeling and rendering to restore 3d geometric structure of scenes from 2d images. Modeling becomes faster and more convenient, which can achieve high rendering speed and high sense of reality.
Walters guides students through the use of walters 3D printers to produce 3D models.
In the process of practice, in view of the teachers’ questions, we have sorted out a few points:
When do you need support?
Model printing accuracy is not enough to solve?
Why is the model drawn when it is printed?
The lecturer also gave detailed answers to the questions raised by the students:
1. When the model we selected has holes at the bottom and there are many places where the model is suspended, support shall be added according to the actual situation;
2. Adjust the height and printing speed before printing. The lower the height, the finer the printing; The slower the printing speed, the finer the printing accuracy, etc.
3. Wire-drawing and surface roughness will occur when the temperature before printing does not reach the temperature required by the model. The model shall not be printed until the temperature reaches the standard;
– Students operation –
On the day of the activity, teachers designed and completed meaningful works by themselves, which not only made teachers feel the charm of technology, but also realized the gap between traditional technology and modern technology.
Teachers generally reported that the training course was very successful, which not only broadened their horizon, but also enabled them to master relevant 3D printing skills.
As an important way to realize digital production, 3D printing requires schools to provide more comprehensive scientific and technological talents with 3D technology for the country. We will continue to conduct in-depth research on innovative 3D printing education to provide better courses and better equipment for schools.
