Vat photopolymerization (VP) is a 3D printing (or additive manufacturing) technology that is capable of fabricating parts with complex geometries with very high resolution. These features make VP an attractive option for the fabrication of scaffolds that have applications in tissue engineering. However, there are few printable materials that are biocompatible and allow cells attachment. In addition, those that have been reported cannot be obtained commercially and their synthesis requires substantial resources and expertise. A novel resin composition formulated from commercially available components was developed, characterized, and printed. Scaffolds were printed with high fidelity. The scaffolds had mechanical properties and water contents that suggested they might be suitable for use in tissue engineering. Fibroblast cells were seeded on the scaffolds and successfully adhered and proliferated on the scaffolds. The growth, migration, and differentiation of cells is influenced by the environmental stimuli they experience. In engineered constructs, the scaffold provides many of stimuli. The geometrical features of scaffolds, including how porous they are, the size and shape of their pores, and their overall size are known to affect cell growth. However, scaffolds that have a variety of pore sizes but identical pore shapes, porosities, and other geometric parameters cannot be fabricated with techniques such as porogen leaching and gas foaming. This has resulted in conflicting reports of optimal pore sizes. In this work, several scaffolds with identical pore shapes and porosities but pore sizes ranging from 200 μm to 600 μm were designed and printed using VP. After seeding with cells, scaffolds with large pores (500-600 μm) had a large number of evenly distributed cells while smaller pores resulted in fewer cells that were unevenly distributed. These results suggest that larger pore sizes are most beneficial for culturing fibroblasts. Multi-material tissue scaffolds were fabricated with VP by selectively photocuring two materials into a single part. The scaffolds, which were printed on an unmodified and commercially available VP system, were seeded with cells. The cells were observed to have attached and grown in much larger numbers in certain regions of the scaffolds which corresponded to regions built from a particular resin. By selectively patterning more than one material in the scaffold, cells could be directed towards certain regions and away from others. The ability to control the location of cells suggests that these printing techniques could be used to organize cells and materials in complex ways reminiscent of native tissue. The organization of these cells might then allow the engineered construct to mimic the function of a native tissue.

Polysiloxanes, also referred to as 'silicones' encompass a unique and important class of polymers harboring an inorganic backbone. Polysiloxanes, especially poly(dimethyl siloxane) (PDMS) the flagship polymer of the family, observe widespread utilization throughout industry and academia thanks to a plethora of desirable properties such as their incredible elongation potential, stability to irradiation, and facile chemical tunability. A major complication with the utilization of polysiloxanes for mechanical purposes is their poor resistance to defect propagation and material failure. As a result polysiloxane materials ubiquitously observe reinforcement in some fashion: reinforcement is achieved either through the physical or chemical incorporation of a reinforcing agent, such as fumed silica, or through the implementation of a chemical functionality that facilitates reinforcement via phase separation and strong associative properties, such as hydrogen bonding. This research tackles polysiloxane reinforcement via both of these strategies. Facile chemical modification permits the construction PDMS polymer chains that incorporate hydrogen bonding motifs, which phase separate to afford hydrogen bond-reinforced phases that instill vast improvements to elastic behavior, mechanical and elongation properties, and upper-use temperature. Novel nanocomposite formulation through the incorporation of MQ nanoparticles (which observe widespread usage in cosmetics) facilitate further routes toward improved mechanical and elongation properties. Furthermore, with growing interest in additive manufacturing strategies, which permit the construction of complex geometries via an additive approach (as opposed to conventional manufacturing processes, which require subtractive approaches and are limited in geometric complexity), great interest lies in the capability to additively manufacture polysiloxane-based materials. This work also illustrates the development of an MQ-reinforced polysiloxane system that is amenable to conventional vat photopolymerization additive manufacturing: chemical modification of PDMS polymer chains permits the installation of UV-activatable crosslinking motifs, allowing solid geometries to be constructed from a liquid precursor formulation.

Based on the 3D printing system developed by the laboratory, this thesis develops the LCD-type photo-curing system with UV light source for the first time, and analyzes the influence of the light source factor on the printing. Since it is the first time to use this UV LED light source film group, in order to measure the power supply of the film group, the power supply is used to supply the voltage and current required by the light source film group and the POWERMETER instrument is used to measure the supply wattage. The intensity of light energy. In addition, the pattern exposure experiment was used to test the uniformity of light, formability and precision. Design a heat dissipation system to reduce the temperature of the high-energy light source module to increase the service life of the module and prevent excessive heat energy from affecting the speed at which the resin is cured. In the machine control and LCD panel graphic display, the Raspberry Pi with Python program for transmission control, in order to do the overall print test. At the end of the experiment, the 405nm wavelength UV LED light source module was compared with the commercial machines Phrozen and Arkuretta used by most consumers. Although the three are the LCD type machine, they use different light source modules. The difference in exposure light source can affect the results of printing, such as dimensional accuracy, sharpness of the edge of the object, and so on.

This study is about a mobile device vat photopolymerization 3D printing system. The system uses a mobile device instead of an expensive laser or a UV lamp to be the light source and pattern generator. Using a timing belt and a linear slide instead of a screw and a shaft to drive the Z-axis stage. This system allows larger positioning tolerance and has high z-axis resolution at the same time by virtue of the flexibility of timing belt. Besides, this study established a standard operating procedure for adjusting the important parameter in the 3D printing process, the “exposure time”. This procedure can quantify the curing degree of the resin by using the Fourier Transform Infrared Spectrometer (FTIR). The quantified curing degree can be used to readjust the exposure time of the 3D printing system when the light source is changed (e.g., the light source is changed from a smartphone to a tablet or another smartphone), let the 3D printing system can operate like the light source is never changed. Finally, measuring the dimensional deviation of the mobile device 3D printing system by printing some samples. The result shows that the dimensional deviation of the X-Y axis is under 260μm by using commercial resin “NT-01” and is under 180μm by adding inhibitor into the resin “NT-01”. The Z-axis dimensional deviation is under 60μm no matter adding inhibitor or not.

The DLP systems is still in development, but most of the systems use DLP or laser as the light source. Most multi-material machines are top-illuminated and there are few down-lit multi-color multi-material 3D printing. This multi-color multi-material 3D printing system used a mobile device, with a rotating disc that can be assembled with several material slots. This study is to improve the multi-color light-curing 3D printing system and is the same as the original system, which uses a portable device and a rotating disk. The improved machine has the function of printing multi-color and printing Multi-materials, and corrects problems that occurred on the original system. The improved positioning accuracy of the rotating disc can be increased by more than 50%. When printing large objects, it will not directly hit the resin tank; and the problem that the Mobile phone is dragged by the turntable will also be sloved, the Mobile phone platform will keep away before the turntable turns away. When the dial is positioned and then returned to the original position, the mobile phone will not be driven by the rotating disc during printing, which improves the success rate of printing.

Повний текст джерелаThree-dimensional printing (3DP) has demonstrated great potential for multi-material fabrication because of its capability for printing bespoke and spatially separated material conformations. Such a concept could revolutionise the pharmaceutical industry, enabling the production of personalised, multi-layered drug products on demand. Here, we developed a novel stereolithographic (SLA) 3D printing method that, for the first time, can be used to fabricate multi-layer constructs (polypills) with variable drug content and/or shape. Using this technique, six drugs, including paracetamol, cffeine, naproxen, chloramphenicol, prednisolone and aspirin, were printed with dfferent geometries and material compositions. Drug distribution was visualised using Raman microscopy, which showed that whilst separate layers were successfully printed, several of the drugs diffused across the layers depending on their amorphous or crystalline phase. The printed constructs demonstrated excellent physical properties and the different material inclusions enabled distinct drug release profiles of the six actives within dissolution tests. For the first time, this paper demonstrates the feasibility of SLA printing as an innovative platform for multi-drug therapy production, facilitating a new era of personalised polypills.
