Which material is best to choose for 3D printing prototype?

3D printing(SLA/SLS) materials are crucial in the 3D printing process, so choose the right 3D printing material for the desired model. These factors are divided into two categories based on the purpose of making the model: appearance verification models and structural verification models.

1. Appearance verification model

This type of model has higher requirements for appearance. It is visible and touchable. It can intuitively display the designer's creativity in the form of physical objects, avoiding the disadvantage of "it looks good when drawn but not when made". Appearance verification model production is essential in the process of new product development and product appearance refinement.

Based on the needs of appearance verification models, it is recommended that you choose photosensitive resin 3D printing (including high-toughness photosensitive resin and transparent resin)
2. Structural verification model

In the product design process, from design plan to mass production, molds are generally made first. The production cost of molds is relatively expensive. Large molds are worth hundreds of thousands or even millions, and the delivery time is relatively poor. Usually the delivery time is almost a month. If the mold is made and the product is injection molded, and problems are found, the loss can be huge. As you can imagine, the mold needs to be constantly modified.

Therefore, if the requirements for precision and surface quality are not high, you can choose low-cost, cost-effective materials, such as ABS resin and other materials. The plastic consumables now available on the market are mainly resin.

If you have high requirements on appearance and structure, it is recommended to try nylon 3D printing(SLA/SLS). The main cost of 3D printing is the purchase of materials. You just need to choose the one that suits you according to your needs.
