3D Printing has had its limitations when it comes to materials, and one of them was glass. Although, Scientists in Germany have developed a method to create small, transparent, and intricate parts using a new “liquid glass” technique. This has opened up a range of possibilities for rapidly manufactured glass products and objects since it uses the SLA 3D Printing method which creates much finer details and smoother finishes over FDM.
The “liquid glass” method works by combining glass powder and liquid polymer, which is then formed a SLA 3D Printer. The 3D printed object is then placed in a high-temperature oven, which burns the polymer away, leaving the glass particles to fuse together, making the object transparent. The results are detailed and strong glass parts, capable of withstanding temperatures of 1,472 degrees Fahrenheit. This glass printing technique will eliminate the need for chemical etching with hydrofluoric acid and allows for the creation of seamless closed cavities and channels, which cannot be achieved through traditional glassblowing methods.
