3D Printing-17

Tengxing Precision offers a range of high-quality 3D printing (additional manufacturing) services, including FDM, SLA, SLS, and SLM. This allows for 3D printing of both plastics and metals, providing options for prototyping and production. 3D printing is a great way to create one-off parts or small batches, and can be used to create complex geometries that are impossible to achieve without traditional manufacturing processes.

Advantages of 3D Printing

1. Affordability: Because 3D printing uses only the necessary materials and requires no tools, it is one of the most affordable manufacturing processes for single-use parts or small batches.

2. Geometry: Band-Trongse 3D printers use computer-controlled nozzles to create part layers by layer, which can be used to create highly complex shapes, including intricate internal geometries.

3. Efficiency: A part can be printed in hours after being designed using CAD software, without lengthy setup steps.

4. Adaptability: Because 3D printed parts do not require tools, there is less risk involved in creating parts. If a problem is found after printing, it can be digitally modified without replacing expensive tools.

5. Environmental Factors: While 3D printers require electricity to run, there is generally no material waste involved. On the other hand, processing methods such as machining generate waste. There is no difference. It really is worth the extra cost.

How to Choose a 3D Printing Process

If you need help finding the right 3D printing process for you, you can establish a consultation and planning phase with our team of additive manufacturing experts.

All 3D CAD files you wish to print must be reviewed by the design and production teams so they can be optimized to meet design requirements. These requirements will differ between FDM, SLA, SLS, and SLM 3D printing, so be sure to optimize the CAD model for the 3D printing process you wish to use.

What is Precision Metal Parts Manufacturing?

Precision metal parts manufacturing refers to the process of shaping metal materials—such as steel, aluminum, copper, and stainless steel—into high-accuracy, complex components using techniques like turning, milling, grinding, stamping, and CNC machining. The core of this process lies in controlling dimensional tolerances (as tight as ±0.001mm), geometric tolerances, and surface finishes. It is widely applied in industries such as automotive, medical devices, aerospace, and telecommunications.

What Are the Main Processes in Metal Parts Manufacturing?

Common processes include: CNC Machining: Suitable for complex 3D shapes, offering high precision and flexibility. Stamping: Ideal for high-volume production of thin-walled metal parts, with high efficiency. Turning: Primarily used for rotational parts like shafts and sleeves. Milling: Used for machining planes, curves, slots, and holes. Wire EDM / EDM: For machining high-hardness materials or complex molds. Laser Cutting / Waterjet Cutting: Suitable for precision sheet metal blanking. Surface Treatment: Such as plating, anodizing, sandblasting, and passivation, for corrosion resistance or aesthetics.

How to Choose the Right Metal Material?

Selection should consider: Functional Requirements: Strength, hardness, wear resistance, corrosion resistance, conductivity, etc. Process Suitability: Aluminum (easy to machine, lightweight), stainless steel (corrosion-resistant), copper (good conductivity), titanium alloys (high strength, biocompatible). Cost and Lead Time: Common materials (e.g., 45# steel, 6061 aluminum) are cost-effective and readily available; specialty alloys (e.g., Inconel, molybdenum) are more expensive and may require pre-ordering.

What Are the Key Factors Affecting the Price of Metal Parts?

Material Cost: Raw material type, usage, and market fluctuations. Complexity of Machining: Number of processes, precision requirements, special treatments (e.g., mirror polishing). Order Quantity: High volumes can amortize mold/programming costs, reducing unit prices. Quality Certifications: Certifications like medical (ISO 13485) or automotive (IATF 16949) may increase management costs. Surface Treatment and Packaging: Special coatings, vacuum packaging, etc., add to the cost.

How Are Tolerance Grades Generally Classified in Part Manufacturing?

Standard Tolerance: ±0.1mm or above, suitable for structural parts, housings, etc. Precision Tolerance: ±0.01mm to ±0.05mm, suitable for mechanical assembly parts. High-Precision Tolerance: Within ±0.005mm, suitable for critical components in aerospace, optical instruments, etc. Recommendation: Define tolerances based on actual functional needs, as unnecessarily tight tolerances significantly increase costs.
