AbstractThis article describes a method of in-situ process monitoring in the digital light processing (DLP) 3D printer. It is based on the continuous measurement of the adhesion force between printing surface and bottom of a liquid resin bath. This method is suitable only for the bottom-up DPL printers. Control system compares the force at the moment of unsticking of printed layer from the bottom of the tank, when it has the largest value in printing cycle, with theoretical value. Implementation of suggested algorithm can make detection of faults during the printing process possible.

Deposition Modeling

The adoption of open-source digital manufacturing technologies in small art workshops may improve their competitiveness. Pieces modeled by computer and made with FDM (Fused Deposition Modeling) 3D printers that use PLA (polylactic acid) can be implemented in the procedures of artistic casting. However, models printed by PLA are limited to approximate minimum sizes of 3 cm, and the optimal layer height resolution is 0.1 mm. These sizes and resolutions are not suitable for creating microsculptures used, in many cases, in jewelry. An alternative to solve this limitation, is to use a DMLS (Direct Metal Laser Sintering) 3D printer. However, due to its high cost, it is a technology that is difficult to introduce in small artistic foundries. This work detailed the design and validation of a DLP (Digital Light Processing) 3D printer, using backlit LCD (Liquid Crystal Display) screens with ultraviolet light. Its development is totally “open source” and is proposed as a kit made up of electronic components, based on Arduino and easy to access mechanical components in the market. Most parts can be manufactured in low cost FDM (Fused Deposition Modeling) 3D printers. The result is an affordable, high resolution (0.021 mm), and open-design printer that can be implemented in artistic contexts.

AbstractTraditional 3D printing based on Digital Light Processing Stereolithography (DLP-SL) is unnecessarily limiting as applied to microfluidic device fabrication, especially for high-resolution features. This limitation is due primarily to inherent tradeoffs between layer thickness, exposure time, material strength, and optical penetration that can be impossible to satisfy for microfluidic features. We introduce a generalized 3D printing process that significantly expands the accessible spatially distributed optical dose parameter space to enable the fabrication of much higher resolution 3D components without increasing the resolution of the 3D printer. Here we demonstrate component miniaturization in conjunction with a high degree of integration, including 15 μm × 15 μm valves and a 2.2 mm × 1.1 mm 10-stage 2-fold serial diluter. These results illustrate our approach’s promise to enable highly functional and compact microfluidic devices for a wide variety of biomolecular applications.
