PRO6600 Ultra-High Resolution 4K Production Ready Optical Engine
May 7, 2024
To exceed the ever more stringent requirements of stereolithography additive manufacturing, Wintech has launched
the PRO6700. The PRO6700 is based on the 0.67” DLP670S DMD (2716×1600 pixels) and the DLPC900ZPC chipset
from Texas Instruments. The PRO6700 is based on the existing PRO6600’s architecture but utilizes the industrial
projection focused LightCrafter chipset. This chipset allows for the use of multiple I/O triggers and the use of TI’s
LightCrafter software and GUI. This light engine is ideal for 3D Printing requiring maximum irradiance and image
quality.
The PRO6700’s modular architecture allows for quick, low-cost modifications to the base light engine that minimize
both expense and time to get to series production. The system is optimized for Luminus Devices CBM-120 UV LEDs.
The PRO6700 supports high intensity monochrome
projection. An all glass optical architecture (including
the prism and flys eye lens) and all metal mechanical
architecture were chosen to increase image quality
and total system efficiency. Wintech’s in-house
wideband optical coatings are optimized for 381-
650nm. Optics configurations are similar to the
PRO4500 and PRO6500 and are 0% offset. The
available projection lenses for the PRO6700 include a
50um or 70um pixel lens optimized for 3D Printing.
These lenses provide a field of view of 134x75mm and
192x108mm respectively. Custom lenses, if needed,
can be fabricated in about three months. The guaranteed minimum system irradiance for the PRO6700 is greater than 3600mW @ 405nm and 3200mW @ 385nm.
This results in a minimum energy density of 31mW/cm2 @ 385nm using the 50um pixel lens. Uniformity is specified
at a class leading > 90% and the distortion specification is the industry benchmark at 0.1% , perfect for high quality
3D printing applications. Contrast ratio is over 500:1.
The PRO6700 incorporates individual DMD and LED driver PCBs. This maintains modularity for the system and
ensures low cost modifications to the PCB. The DMD-driver PCB includes 24V locking power connection, HDMI port
for image transfer, RS232 serial port and mini-USB for system control. Thermal management is provided by heat sinking via copper heat piping and active fans. The system also incorporates a LED junction temperature sensor for
monitoring LED performance. The system size is 260x150x245mm including the projection lens and weighs less than
3.2kg.
The PRO6700 software allows for easy integration of the PRO6700 into new or existing 3D printing systems.
