Formlabs Form 4 Resin 3D Printer

The Formlabs Form 4 Kyoshi Resin 3D Printer is a professional resin 3D printer / masked SLA 3D printer / Low Force Display 3D printing / rapid prototyping / additive manufacturing / professional resin 3D printer / rapid prototyping 3D printer / additive manufacturing equipment developed by Formlabs and supplied in Vietnam by Kyoshi Technical Joint Stock Company.
The equipment is used to convert 3D design data into visual prototypes, assembly verification models, test parts, jigs, fixtures, manufacturing aids, and small-batch production. The Form 4 is suitable for R&D departments, mechanical engineering companies, electronics companies, machine manufacturing companies, mold and die companies, and product development units.
The Form 4 is not limited to a fixed application. The application method is chosen based on the size, shape, accuracy, mechanical properties, surface finish, resin type, production volume, and intended use of each part.
The system may include the Form 4 printer, resin tank, build platform, PreForm software, Form Wash cleaning unit, Form Cure post-curing unit, and standard or engineering resins.
The Form 4 utilizes masked stereolithography technology combined with Low Force Display (LFD). A light source shines through a masking system to simultaneously cure the cross-section of each resin layer. This mechanism allows the printer to create a large part or multiple small parts in a single cycle.
The printer has a build volume of approximately 200 × 125 × 210 mm, suitable for various engineering prototypes, device enclosures, mechanical parts, and small production batches. Actual print time depends on part height, layer thickness, material, orientation, and support structure quantity.

1. Key Product Features

The Form 4 combines build speed, surface finish, and a material library within a professional resin 3D printing ecosystem.
The equipment helps businesses bring prototyping in-house, reduce lead time for external processing, and increase design iteration cycles.
Low Force Display technology helps control peel forces, contributing to parts with smooth surfaces, sharp details, and complex geometries.
The Form 4 can arrange multiple parts on the same build platform. When parts have similar heights, print time does not increase proportionally with the number of parts.
An automatic resin dispensing system, material temperature control, and assistive sensors contribute to more stable operation.
PreForm software supports data import, model orientation, support generation, part arrangement, and sending jobs to the printer.
After printing, parts are washed, dried, post-cured, and surface finished according to the instructions for each resin type.
The Form 4 supports various material groups for visual prototypes, engineering parts, load-bearing components, flexible products, heat-resistant products, or manufacturing aids.

2. What Needs Does the Product Address?

The Formlabs Form 4 Kyoshi Resin 3D Printer is suitable for:
- Rapid prototyping from CAD data.
- Shape and dimension verification.
- Component assembly testing.
- Developing multiple design iterations.
- Manufacturing jigs, fixtures, and inspection gauges.
- Producing positioning trays and holders.
- Prototyping electronic device enclosures.
- Fabricating production line aids.
- Small-batch production before mold investment.
- Creating presentation models and functional prototypes.
- Supporting R&D and technical training.
- In-house prototype production.
For R&D departments, the printer helps engineers quickly evaluate designs and adjust data before official production.
For mechanical factories, the Form 4 can be used to fabricate jigs, fixtures, storage trays, protective covers, and tools suitable for resin properties.
For electronics companies, the equipment supports creating device housings, circuit board holders, sensor mounting parts, and component layout verification models.
The Form 4 does not completely replace CNC, injection molding, or casting but complements with a flexible solution for small-volume products, complex geometries, and frequently changing designs.

3. Key Technology and Components

The system may include:
- Form 4 resin 3D printer.
- Low Force Display technology.
- Light source unit and masking system.
- Resin tank.
- Build platform.
- Material heating system.
- Print process control sensors.
- Automatic resin dispensing system.
- PreForm software.
- Form Wash cleaning unit.
- Form Cure post-curing unit.
- Standard and engineering resins.
- Support removal and product finishing tools.
Design data is imported into PreForm to select orientation, layer thickness, supports, and part placement. The printer then creates the product layer by layer from resin.
Printed parts need to be washed to remove excess resin, post-cured to achieve mechanical properties, and further processed by removing supports, polishing, or painting if necessary.
Customers should provide:
- 3D design data.
- Product dimensions and shape.
- Tolerance requirements.
- Surface quality.
- Quantity to be produced.
- Intended use.
- Load and operating temperature.
- Hardness, strength, or flexibility.
- Required completion time.
- Post-processing requirements.

4. Benefits for Customers and Businesses

The Form 4 helps businesses proactively prototype, reduce lead time, and enable early detection of errors related to dimensions, shape, or assembly.
The equipment allows for testing multiple design iterations before investing in molds or moving to mass production.
In-house prototype printing also supports design data security and reduces reliance on external service providers.
The ability to print multiple parts in a single cycle increases productivity for jigs, fixtures, trays, holders, and small components.
The resin ecosystem allows for material selection based on specific application objectives, from visual prototypes to engineering parts and production tools.
Kyoshi supports customers in selecting the appropriate printer, resin, washing equipment, post-curing system, and usage procedures tailored to their actual needs.
