This SBIR Phase 1 project aims to develop a novel continuous rotational spiral solidification technology platform called Heliolithography (HL) to enable economical mass production of functional end-use 3D printed parts. The potential outcome of this feasibility study would be improving speed and performance of the prototypes to demonstrate key advantages of the process. This highly beneficial platform aims to advance 3D printing technology into production of functional parts. Its success would contribute to widespread job creation in the U.S. Manufacturing sector.Heliolithography utilizes continuous rotation to overcome the inefficiencies of a serial layer to layer process typical of stereolithography machines (SLA) that must reset, re-position, re-supply material so the next layer can be made. The rotating method serves as a continuous method to cure material, removes the adhesion force issue that impedes many SLA processes from scaling up, and resupplies new material to be cured in one motion. If successful, this will serve as a significant leap forward in the field that will provide greater throughput for mass producing and mass customizing 3D prints while allowing for the use of a broader range of advanced materials with higher viscosities. The research project will also focus on the development of an advanced non-stick coating and a tiled, high power, high resolution light engine. A tethered liquid interface nano-coating will be evaluated by bond line release and wear rate/durability tests. The performance of the light engine will be validated through direct power output measurements and also through extended functional testing for dimensional accuracy, repeatability, and tensile & impact strengths of the printed parts.

这个SBIR第1阶段项目旨在开发一种称为Heliologhoghy（HL）的新型连续旋转螺旋固化技术平台，以实现功能性最终用途3D印刷零件的经济质量生产。这项可行性研究的潜在结果将是提高原型的速度和性能，以证明该过程的关键优势。这个非常有益的平台旨在将3D打印技术推向功能零件的生产。它的成功将有助于美国制造业的广泛创造就业机会。Heliolighography利用连续旋转来克服串行层的低效率，以将必须重置，重新位置，重新供应材料的立体光刻机器（SLA）的典型过程分层，因此可以制作下一个层。旋转方法是治愈材料的连续方法，消除了阻碍许多SLA过程扩展的粘附力问题，并为一种运动补充新材料。如果成功的话，这将是该领域的重大飞跃，可以为质量生产和质量定制的3D打印提供更大的吞吐量，同时允许使用更广泛的高级材料，具有较高的粘度。该研究项目还将着重于开发先进的非粘涂层和瓷砖，高功率，高分辨率轻型发动机。束缚液接口纳米涂层将通过键释放和磨损速率/耐用性测试评估。轻型发动机的性能将通过直接电源输出测量以及扩展功能测试来验证，以获得尺寸的精度，可重复性以及打印零件的拉伸和冲击强度。
