What is the definition of rapid prototyping?

Rapid prototyping is a technique that verifies design concepts by quickly constructing three-dimensional models (such as rapid mockup). The core goal is to shorten product development cycles and reduce trial and error costs. The prototype meaning is not only in the rapid presentation of physical model, but also in the accurate matching of function and user experience through iterative optimization, so as to establish an efficient verification bridge between virtual design and physical manufacturing.

What materials are required for rapid prototyping? ​

In the field of rapid prototyping, the choice of materials directly affects the performance, cost and application scenario of the prototype. According to different design requirements, commonly used materials can be divided into the following categories:

• Plastic materials: Such as PLA, ABS, have the characteristics of convenient processing and low cost, suitable for appearance verification or basic function testing of rapid prototypes.
• Photosensitive resin: High precision, smooth surface, commonly used in dentistry or jewelry industry fine and rapid prototypes, supporting the formation of microstructures.
• Metal materials: Such as stainless steel and titanium alloys can be processed through metal 3D printing or CNC machining to meet the aerospace and automotive industry's demand for high-strength, rapid prototypes.
• Nylon material: Resilient and suitable for manufacturing rapid prototypes of removable parts or complex assembly structures, such as industrial equipment prototypes.
• Composites material: Such as carbon fiber reinforced nylon are a combination of lightweight and high strength and are widely used as prototypes for performance testing in new energy vehicles or aerospace.
• Silicone and wax molds: Silicone is used to simulate flexible components, while wax molds are used as casting mother molds for rapid prototypes connecting traditional processes.

What are the advantages of 3D printing in rapid prototyping?

1.Reduce the R&D cycle significantly

3D printing, which does not require traditional moulds or complex processing steps, converts digital models directly to physical prototypes, reducing the delivery time of rapid prototyping from a few weeks to a few days, and is particularly suitable for emergency projects or iterative verification needs.

2.Design freedom

Supporting shapes that are difficult to achieve with traditional techniques, such as complex geometric structures, hollow embeddings and irregular surfaces, gives designers more creative space during rapid prototyping.

3.Flexible production and controllable costs

Compared with traditional injection molding and opening mode, the production cost of single piece or small batch is greatly reduced, and the waste of resources is avoided. plastic prototypes, for example, can be mass-produced directly through FDM or SLA technology, saving over 90% of tool costs.

4.Diversified material adaptation

All-material systems covering everything from low-cost PLA to industrial-grade metallic powders meet the needs of different rapid prototyping scenarios. For example, photosensitive resin are used for high-precision appearance models, while metal alloys are used for mechanical performance verification.

5.Rapid iteration and validation

Allowing direct modification and reprinting of digital models on a single device enables an efficient cycle of design, print, test, correction, compressing traditional 5-6 iterations into 2-3, greatly increasing R&D efficiency.

6.Reduce material waste

The characteristics of on-demand consumer goods in additive manufacturing reduce waste by more than 70% compared to subtractive processing (e.g. CNC) and are therefore particularly suitable for environmentally demanding rapid prototyping projects.
