3D Systems Looks to the Future of Manufacturing with Figure 4

Over the last few decades, additive manufacturing (AM) has been sold as an alternative to more traditional forms of manufacturing. It has been able to grow largely in part to its flexibility and usefulness as a rapid prototyping tool. However, as nearly any AM pundit will report, for the technology to revolutionize manufacturing, it must get much faster.

3D Systems (3DS) has been hard at work developing tools that might allow it to meet that very goal. The company took its first steps toward mass manufacturing while developing Project Ara, but its new, developmental industrial AM system is far more ambitious. Based on 3DS’ tried-and-true stereolithography (SLA) process, its Figure 4 technology aims to bring 3D printing to the factory floor with the modular SLAbot-2.

Unlike some AM systems such as the BAAM system that look to produce large objects in quantity without much worry to initial strata lines, Figure 4 is focused on producing a quantity of parts-sized objects with high resolution. 3DS claims its new system is up to 50x faster than existing systems, while still retaining the fine detail characteristic of SLA prints.

Speed of printing opens up new material possibilities, based on the idea that it’s possible to create less stable vats of material because the materials can have an active life of days or hours instead of years. According to the company, this allows for hybrid photopolymers designed for toughness, durability, bio-compatibility, high temperature deflection and elastomeric properties.

Another change with Figure 4, and the SLAbot-2 is the standard inclusion of a robot arm to assist with the manufacturing process. The arm is responsible for loading and unloading trays into and out of material vats, which allows several build processes to run simultaneously. Additionally, the arm moves completed builds from the vats to automated cleaning and post-processing stations, allowing for continuous parts production without requiring human intervention.

Each SLAbot-2 essentially acts as a modular station. By combining multiple stations, you create a robotic production line that (theoretically) further speeds up the rate of production by allowing the arms to assist each other with manufacturing duties. CAD data and materials go in one end, finished parts come out the other. Changing the line over to produce different parts is as simple as changing the CAD files, which offers significant savings over injection molding where new parts mean new molds.
