This invention relates to the field of 3D printing used to make a dental aligner for the purpose of straightening teeth or a mouthguard for the purpose of protecting teeth. The appliance is a hard polymer layer that encases the upper, lower or both sets of teeth to exert correcting forces on the teeth to realign their position, optionally these clear aligners can also incorporate a wire for more rapid treatment. This invention describes a method of directly 3D printing the aligner or mouthguard from liquid photopolymer rather than as it is currently manufactured by thermoforming plastic over a custom model and then trimming it to the desired size.
本发明涉及 3D 打印领域,用于制作矫正牙齿的牙齿矫正器或保护牙齿的护齿器。这种矫正器是一种硬质聚合物层,它包裹着上、下或两副牙齿,对牙齿施加矫正力,以重新排列其位置,这些透明的矫正器还可以选择性地加入一根钢丝,以实现更快速的治疗。本发明描述了一种用液态感光聚合物直接 3D 打印矫正器或护齿的方法,而不是目前通过在定制模型上热成型塑料,然后修剪成所需尺寸来制造矫正器或护齿的方法。

This invention relates to the field of 3D printing used to make a 3D object where a 3D printed object is formed using electromagnetic radiation emitted from a visual display screen or emissive pixel array screen illuminated by radiation sources with effectively non-overlapping wavelength emission spectra with the effect of creating two different polymerised properties in the object.
