Almost all industries use photosensitive resin 3D printers in the process of making hand board models, architectural sand table models, home appliance hand board models, medical equipment hand board models, automotive hand board models, office equipment hand board models, computer digital hand board models, etc. Industrial SLA3D printers can be given full play.
Photosensitive resin 3D printer refers to SLA industrial 3D printer with liquid resin as processing material, also known as light-curing 3D printer. With strong modeling ability, it can produce products of any geometry and is widely used in the field of hand board model production.
The production of hand board models has gone through three stages: manual production, CNC engraving to 3D printing, which greatly improves the production efficiency. Due to the high requirements of size and precision of hand board models, the most suitable 3D printing technology is SLA 3D lithography.
SLA 3D printer has its limitation, it can only print specific material – photosensitive resin, similar to ABS plastic. Therefore, photosensitive resin 3D printers are mainly used for making plastic hand board models and are not suitable for metal hand board models.
The appearance hand board is mainly used to check the appearance. Size, other properties of the material is less demanding, photosensitive resin 3D printer can print any shape of the appearance hand board model, the more difficult the product, the higher the efficiency of 3D printing, the lower the cost. Nowadays, most of the appearance hand boards are made by 3D printers.
Structural hand board has certain requirements on the strength of the material. The photosensitive resin 3D printer can meet some of the structural hand board production. For those with particularly high strength requirements, compound mold process or SLS nylon 3D printer can be used.
- Small batch customization.
For some users’ small batch customization requirements, if it is only for indoor general decoration, photosensitive resin 3D printer can be used. If the requirement is specific plastic material or temperature resistance. The strength requirement is high, then silicone composite mold and low pressure infusion process must be used.
- Soft plastic hand board model.
Photosensitive resin can be divided into soft material and hard material. Most of the time, hand board models use hard material, a few hand board models use soft elastic material. At this time, soft material photosensitive resin 3D printer has a use. It is usually used to make silicone hand board.
- Transparent hand board model.
In the past, transparent hand board models were usually made of acrylic material engraved by CNC machines, but now it is almost completely replaced by photosensitive resin 3D printers. It can produce translucent and fully transparent effects and add other colors on top of the transparency.
