Knowledge: New laminating resin printing technology for sls sla 3D printing of micro-structure by MicroMaker3D
On November 15, China's 3D printing network, Callaghan, New Zealand, introduced a laminated resin printing (LRP) technology, a new 3D printing technology, which can realize the rapid prototyping of the high-resolution micro-scale structure.
Laminated resin printing (LRP) can quickly, easily and economically create a variety of printing structures for applications such as electronics, wearable devices, sensors, Internet of things devices, etc.
Callaghan says it allows developers to print sub-millimeter-class structures with a density of up to 100% of complex geometric shapes, very low thickness, and imaging speeds of up to one second per layer, regardless of complexity or density. Co-inventor Andrea Bubendorfer and Andrew Best developed LRP, to meet the needs of rapid production of micro-scale structures in an efficient, convenient and economical manner. "Micro-processing, which produces very small high-value equipment, is New Zealand's export industry. Until now, however, making these micro-structures had been slow and expensive. "Co-inventor Andrea Bubendorfer said.
"by contrast, 3D printing has changed the way we make products, but it can't work on the small scale needed for micro-machining." She added. Bubendorfer and co-inventors began to develop methods to meet the needs of rapid production of micro-scale structures in an efficient, convenient and economical manner. "from childhood to small, we are talking about 5 microns. And human hair is about 100 microns. "
The MicroMaker3D team is supported by the IDTechEx Launchpad program and KiwiNet through funding, planning and advice, and engineering expertise from the mechatronics engineer and the Callaghan Innovation Advanced Engineering team at the University of Macy's incremental Manufacturing Center. Advice and encouragement from Professor of robotics and expert in augmentation Manufacturing at Johan Potgieter (Macy University and Professor of Product Development at Olaf Diegel (and World renowned 3D Printer expert. The project also attracted $684000 in seed funding from KiwiNet.

LRP is a multi-functional printing technique:
(1)Independent planar structure (shadow mask, optical slit, optical encoder, filter, mesh, etc.)
(2)Structure on paper, fabric, and PCB substrates (wearable devices, disposable microfluidic, chip laboratory equipment)
(3)Printed electronic mask
(4)Micro 3D printing (micro-assembly, MEMS spring)
(5)Suspension structures in elastic materials-suitable for micro-sensor elements
The technology is powerful:
(1)affordable and easy to use
(2)Fast, imaging speed of 1 second per layer, independent of complexity or density
(3)No clean room required
(4)Extend from prototype to production using the same high-quality material
LRP is good at:
(1)Rapid prototyping for applications that are important in size and weight
(2)5 micron voxel printing with high precision and high complexity
(3)Printed monolayer and multilayer structure
(4)Production of printed matter with extremely high heat and chemical resistance
(5)Printed on various substrates: paper, fabrics, silicon wafers, PCB
The technology is being used to produce a series of structures. For example:
(1)Shark skin, textured surface
(2)microwell plate(microtiter plate)
(3)Templates, such as microwave antennas
(4)micro-filter
(5)Miniature components, such as gears, lever sprints, needle tips, elastic retaining rings
(6)Patterned conductive orbit
(7)Package structure
