1、 Material Selection Guide

1. Plastic materials

Plastic is one of the most commonly used 3D printing materials due to its wide selection and relatively low cost. The most common plastic materials include polyvinyl ketone (PEEK), ABS (acrylonitrile butadiene styrene copolymer), PLA (polylactic acid), and nylon. Every type of plastic has its advantages and disadvantages, so choosing the material that suits your project needs is very important.

-PEEK: PEEK is a high-performance polymer with excellent heat resistance, corrosion resistance, and chemical stability. It is usually used to manufacture parts that require high temperature and chemical corrosion resistance.

-ABS: ABS is a common plastic material with good strength, impact resistance, and heat resistance. It is suitable for manufacturing large and durable parts.

-PLA: PLA is a biodegradable plastic material typically made from plant-based materials. It is suitable for printing models that require high precision and low strength.

-Nylon: Nylon is a material with good wear resistance, corrosion resistance, and high strength. It is suitable for printing parts that require durability and mechanical properties.

2. Metal materials

Metal 3D printing is receiving increasing attention as it provides the ability to manufacture high-strength and complex shaped parts. One common metal 3D printing technology is Selective Laser Melting (SLM). Here are some commonly used metal materials:

-Titanium alloy: Titanium alloy is a lightweight but high-strength metal with good biocompatibility and corrosion resistance. It is widely used in the fields of medicine and aerospace.

-Stainless steel: Stainless steel is a metal with good corrosion resistance and high temperature resistance. It is suitable for manufacturing durable and aesthetically pleasing parts.

-Aluminum alloy: Aluminum alloy has good strength and lightweight properties. It is commonly used for manufacturing automotive and aircraft components.

2、 Usage skills

1. Model design

Before starting 3D printing, ensure that your model design meets the requirements of 3D printing. Ensure that the model is closed and free from voids or intersections. In addition, avoid excessively overhanging parts or small details, which may lead to printing failure or poor quality.

2. Print settings

The correct printing settings are crucial for obtaining high-quality printing results. Adjust printing parameters such as layer height, fill density, and printing speed to meet your project requirements. Choose a suitable support structure to ensure that there is no distortion or tilt during the printing process.

3. Printer maintenance

Maintaining good maintenance of 3D printers is key to ensuring print quality and extending machine lifespan. Regularly clean the printer nozzle and printing bed to prevent material blockage. Check and replace damaged nozzles or other components to ensure a smooth printing process.

4. Post processing

After completing the printing, you may need to perform some post-processing to achieve the final appearance and performance of the parts. This may include removing supporting structures, polishing surfaces, painting, or other surface treatments.

5. Safety precautions

When using 3D printing technology, it is essential to follow safety precautions. Ensure use in a well ventilated area to prevent the release of harmful gases. At the same time, follow the correct operating procedures and use appropriate personal protective equipment.

conclusion

3D printing technology has brought infinite possibilities to the manufacturing industry and creative design. Understanding the correct material selection and usage techniques is crucial for obtaining high-quality printing results. This article provides tips and material selection guidelines for 3D printing, hoping to be helpful to you in exploring and applying 3D printing technology.
