The main difference between rapid prototyping parts and die parts lies in manufacturing technology, application scenarios, cost and scope of application.
Of course, rapid prototyping and die manufacturing are both methods of manufacturing parts, but they are very different in the implementation process. Here, taking metal parts as an example, the information introduces the difference between these two sheet metal forming processes and methods.
Rapid prototyping is a manufacturing technology that converts digital models into solid models through computer-aided design (CAD). This technology usually uses various rapid prototyping equipment, such as 3D printers, laser forming machines, injection molding machines, etc., to process raw materials according to the shape and size of the digital model, and finally obtain a solid model.
In contrast, die manufacturing is a technology that manufactures molds and uses them to manufacture parts. Molds are usually made of metal or plastic materials and are used to make repetitive shapes of parts during the manufacturing process. This technology usually requires the mold to be manufactured first, and then the mold is used to manufacture parts.
1. Manufacturing technology
Rapid prototyping parts: Rapid prototyping technology is used to convert three-dimensional images into solid models through CNC technology. This technology usually uses materials such as light-curing resin and nylon, with short manufacturing time and low cost, suitable for small batch production.
Mold parts: using mold processing technology, solid materials are processed into the desired shape through mold manufacturing technology. Mold parts usually use materials such as magnesium alloy and aluminum alloy, with long manufacturing cycle and high cost, suitable for mass production.
2. Application scenarios
Rapid prototyping parts: suitable for small batch production and sample production, can quickly produce parts that meet the requirements, especially suitable for product development and market verification stages.
Mold parts: suitable for mass production and long-term stable production, can meet higher production requirements and longer service life.
3. Cost and scope of application
Rapid prototyping parts: low manufacturing cost, suitable for small batch production, can quickly respond to market demand.
Mold parts: high manufacturing cost, but long service life, suitable for mass production, can reduce unit cost and improve production efficiency.
How long does it take to make rapid prototyping parts
The production time of rapid prototyping parts varies depending on the process. For example, CNC machining usually takes 1 to 7 days, depending on the complexity of the part. Simple-shaped parts may only take 1-2 days, while complex-shaped parts may take 5-7 days or even longer. For rapid prototyping processes such as 3D printing, the production time is usually between one and two weeks, which can achieve a rapid conversion from 3D data to 1:1 physical objects.
Rapid prototyping process
Rapid prototyping technology is based on the principle of discrete/stacking molding, which layers the three-dimensional CAD model at a certain thickness and turns it into a very thin two-dimensional plane model. Then data processing and processing parameter setting are performed, and each thin layer is continuously processed in a plane processing manner through the control of the CNC system, and bonded to form.
Application areas of rapid prototyping parts
Rapid prototyping technology is widely used in many fields, including industrial manufacturing, construction industry, medical field, artistic creation, archaeological research and aerospace. In die manufacturing, rapid prototyping technology can significantly shorten the trial production cycle of new products and improve manufacturing flexibility and quality.
Of course, rapid prototyping and die manufacturing are two different manufacturing methods, but they both have unique advantages in manufacturing metal parts. Rapid prototyping can quickly manufacture solid models, while die manufacturing can achieve the manufacture of repetitive shapes.
