3D printing technology is an industrial technology that has rapidly developed in the manufacturing industry. Its principle is rapid prototyping technology, which uses powdery bondable materials and uses the principle of superimposition to print layer by layer to construct entities. The laboratory that studies it is actually a comprehensive laboratory integrating electromechanics, computers, numerical control and new materials. It is a good carrier for comprehensive practical courses. With the birth of the first 3D printed pistol in the United States, this technology is worldwide Many enterprises, scientific research institutions, and universities have seized the opportunity to increase production and research efforts. With the support of national and local government policies, my country's 3D printing technology has developed rapidly in recent years and has good development prospects in various industries. 3D printing is also known as "the key technology to realize digital manufacturing", which covers material molding, reverse engineering, three-dimensional data acquisition technology, computer three-dimensional design and process design, equipment operation and maintenance and other professional knowledge.

In the field of system application in colleges and universities, the construction of laboratories is very important to achieve the goal of training application-oriented talents in my country's 3D printing. In fact, it is not complicated to build a 3D printing laboratory. It is especially important to note that the equipment and instruments in this type of laboratory are cutting-edge equipment. For special high-precision equipment, pay attention to the independence of the constant temperature and humidity area for easy maintenance and maintenance. CEIDI Xidi shared a case study of the construction of a 3D printing innovation laboratory in a university:

3D printing innovation laboratory site requirements

1. Area The site area is about 60 square meters, or an ordinary classroom

2. Regional planning: (1) 3D data collection area; (2) 3D design and data processing area (3) 3D printing experience area; (4) 3D work display area;

3. Regional settings and functions:

1) Three-dimensional data collection area: a set of binocular three-dimensional scanning system: it can scan the object into three-dimensional data, perform point cloud processing, and then carry out subsequent innovative design, which can be used for reverse engineering, industrial (product) design, three-dimensional digital inspection, etc. .

2) Three-dimensional design and data processing area: Primary school adopts UTUDESK123D series software. Students can create with their fingers on the PAD. No complicated processing and technology are needed. The focus is on artistic creation, which can be made of clay sculptures, manual mosaics, and simple designs. 、Operations such as generating three-dimensional data through photos are interesting, easy to operate, and easy for students to learn; middle school uses CAXA design software, students can process the collected data in the computer, and create three-dimensional works independently, such as three-dimensional character design and car model , Future buildings, etc., can directly generate 3D printing common format STL files.

3) D3 printing experience area: equipped with desktop-level FDM equipment and DLP printing equipment, aiming to allow every student to freely create, print the finished product through the desktop, students have close contact with 3D printing, everyone is hands-on, and everyone participates.

4) Professional laser rapid prototyping area: equipped with professional laser rapid prototyping machine and related accessories, laser rapid prototyping machine is a perfect combination of mechanical control, optical technology, computer technology, material science, and art design, allowing students to understand the modern in many aspects and interdisciplinary Manufacturing technology, personally make high-precision, high-quality products, products with practical functions, and understand the production process and technology.

5) Post-processing and color processing area: print out the work for post-processing, you can open silicone molds, spray paint and color processing, so that students can understand the manufacturing process and experience the transformation of manufacturing by 3D printing technology.

6) 3D works display area: wall display racks, integrated in classrooms, corridors, and school public areas to display student works, and can also be equipped with LCD screens to loop student 3D works.

3D printing innovation laboratory decoration construction details

Because the light rapid prototyping machine 25 needs a constant humidity and constant temperature environment, it needs to be operated in a separate closed room in a large laboratory. The specific requirements are as follows:

1. With an area of 15-20 meters, it is recommended to make a fully enclosed partition.

2. If there are households who want to prevent ultraviolet rays, the top bright lights (anti-external lights) are required.

3. Air conditioning, exhaust and dehumidifiers are installed inside to keep constant temperature and humidity.

4. The internal workbench cabinet can hold some common tools, such as gloves, tweezers, alcohol box, small brush, platform scale (the weight of the finished product can be weighed), etc.

5. The 25 machine needs U power supply, 2.5 kilowatts.

6. The environment in this area cannot have a large source of vibration.

7. The desktop machine can be put in the bottom cabinet, and the inside of the cabinet can be put in the waste village.

8. The overall laboratory of the 3D printing innovation laboratory is recommended to be equipped with work display cabinets to display student works

In addition, 3D printing application scenarios have been popularized in medical care, scientific research, product prototypes, cultural relics protection, architectural design, manufacturing, food industry, automobile manufacturing, accessories and accessories. The construction of 3D printing laboratories in different industries will be designed and constructed in accordance with their industry characteristics. CEIDI Xidi emphasizes the construction of laboratories in accordance with local conditions and tailored to the greatest extent, which is to establish high-quality projects in all walks of life to the greatest extent.
