8 Application and Implementation

Note

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

8.1 Application Information

The DMDs are spatial light modulators which reflect incoming light from an illumination source to one of

two directions, with the primary direction being into a projection or collection optic. Each application depends

primarily on the optical architecture of the system and format of the data coming into the DLPC1438 controller.

Applications include:

• DLP 3D Printer

– Additive manufacturing

– Vat polymerization

– Masked stereolithography (mSLA 3D printer)

• Light exposure: programmable spatial and temporal light exposure

DMD power-up and power-down sequencing is strictly controlled by the DLPA2000/DLPA2005. Refer to Section

9 for power-up and power-down specifications. For reliable operation, the DLP300S DMD must be used with the

DLPC1438 controller and DLPA2000/DLPA2005 PMIC/LED driver.

8.2 Typical Application

Figure 8-1 and Figure 8-2 show typical DLP 3D printer system block diagrams using the DLP300S DMD,

DLPC1438 controller, and DLPA200x PMIC/LED driver.
