5 System Block Diagram

In a DLP 3D printing design, the object is specified by a 3D CAD model produced with software running on a PC then converted into 2D cross-section layers generated by an image slicing tool. The best choice for a DLP chip-set depends on the desired object feature size, resolution, printing speed and exposure wavelength. The system control and signal processing is accomplished by the embedded processor, such as TI MSP430™. Power is provided by TI Power device.

To enable customers to get to market faster, Texas Instruments also provides a TI Design for 3D printing applications. A TI Design is a comprehensive reference design that includes schematics, block diagrams, bill of materials, design files, software, and test reports. The 3D printer development platform employs the DLP 3D structured light software development kit and enables developers to build high resolution 3D objects. The free TI Design features the DLP LightCrafter 4500 EVM, showcasing the DLP4500 DMD, to accurately expose object layers. The system also uses TI's low power MSP430 embedded processor to synchronize layer exposure with motor control for precise incremental 3D builds. Get started at ti.com/tool/TIDA-00293.
