Case introduction

Plastic materials are the most common products in our daily life and work, and most of these plastics are formed through thermoplastic molding. This type of product design is also constantly emerging, and it is essential for designers to create 3D models during the product design verification process. Nowadays, 3D printing technology is often used to produce 3D models and verification models, which can provide more efficient and accurate manufacturing solutions.
This case is an audio appearance prototype printed using HXC's SLA3d printing process. The material used is photosensitive resin, and after printing, it undergoes basic manual polishing, measurement and quality inspection, followed by oil touch, and finally assembled as shown in the diagram.

We make plastic product shells for our customers, and when modeling the appearance of the product, we choose different plastic materials based on the intended use of the customer's shell model. Different materials also have different physical properties, for example, if the customer is verifying the appearance structure, then the photosensitive resin used. The advantages of photosensitive resin are relatively smooth and inexpensive, but the disadvantage is that it is relatively brittle; Of course, it is also possible to choose imported photosensitive resin materials to make the structure and appearance of the prototype shell, which will result in better toughness products.

Nowadays, the production process of prototype is becoming increasingly efficient and fast. The characteristic of prototype or product itself is that the more components there are, the longer the supply chain and product line will be, and the more time and cost will be required for assembly and transportation. The characteristic of integrated 3D printing is that it does not require reassembly, thereby shortening the supply chain and saving costs in labor and transportation. 3D printing technology makes the production of prototype components more efficient and fast.
