We need your insights. How do you see the resin 3D printing market and where can improvements be made? Take the树脂3D打印上的聚光灯survey now.
3DPI: How have you seen resin-based 3D printing develop in recent years?
伊扎尔奖牌: I see progress on multiple fronts, the first one is a much deeper understanding of the relationship between optics, hardware, materials, and print performance. Advancing the performance interface technology (aka membranes) to eliminate peel-off forces coupled with continuous improvements in LCD technology which opens the printability aperture by delivering higher resolution and enhanced UV transmission. Couple that with integrated sensors that enables active monitoring and what you get is a printer that can print orders of magnitude faster, using a wider range of photopolymers without any compromise to accuracy or yield.
The other important dimension is software. The ability to bring a higher level of workflow automation including design decision support, file processing, and intuitive guidance enables more users to gain access to 3D printing while lowering the required expertise barriers needed to achieve successful prints the first time. Advances with fleet management and other important MES components brings 3D printing to the production floor allowing customers to better track and inspect parts along the production chain.
Finally, we are all benefiting from significant advancements in photochemistry which opens the aperture to a wider range of functional polymers materials that can even surpass the performances of traditional thermoplastics in certain applications. What’s more, as our photoplastic 3D printers evolve in their ability to manage higher viscosity and higher temp materials it substantially expands the reach and addressable applications into very demanding auto, aero, and consumer product applications.
3DPI: What do you consider the next technology hurdles for photopolymer-based 3D printing to overcome?
伊扎尔奖牌: Time is the only thing money can’t buy, so the need for orders of magnitude higher speed and greater productivity remains our primary purpose along with broadening the range of functional and economicalmaterials。这些都不是容易克服的挑战。一个natural byproduct of faster photopolymeric 3D printing is heat due to the exothermic reaction of the printing process. Another photopolymer challenge is the UV degradation of the parts and weatherability over time. Also, challenges of working with higher viscosity materials will not just disappear. Further innovation is required to reduce the forces that are exerted on parts during the print process. Advancements in thermal and light management could further expand the printability envelope and first print success of photopolymer contributing to a more sustainable process.
3DPI: What applications of vat photopolymerization do you see as under-developed by the market, and why?
伊扎尔奖牌: There is a clear need to expand the availability of hybrid solutions for additive manufacturing. By hybrid I’m referring to a combination of additive and traditional manufacturing for series production. There are some good initiatives along those lines, but I think there are also big opportunities in finding a synergetic approach between traditional technologies and photopolymer 3D printing.
3DPI: Where are opportunities for materials development in regards to vat photopolymerization Technology?
Izhar Medalsy：对于我们所做的每件事的Nexa3D可持续性中，对于我们来说，这是最大，最大胆的机会。例如，有前途的举措使我感到鼓舞，例如，结合了可生物降解的原料，但迫切需要扩大这些最初的努力。
3DPI：在您的打印平台上验证了哪些Loctite树脂？
Kevin McAlea: At Nexa3D, we value the power of an abundant material ecosystem, and we work with a variety of material suppliers to provide the broadest range of material options to our customers. Specific to LOCTITE resins, we have validated General Purpose: Pro410 Prototyping & Modeling Material. Additionally, Functional Materials: x4PP 05: Tough; Semi-rigid, xABS 3843: Rigid; Durable, xPEEK, 147: Strong; Hi-Temp, xFlex, 475: Elastomeric, Medium Soft; with good energy return.
3DPI: What applications are end-users leveraging using LOCTITE 3D resins on your platform?
凯文McAlea:广泛的通用的尘埃rial design, concept modeling, prototyping, as well as production runs of complex, functional parts. Additionally, applications like jigs, fixtures, connectors, tools and molds that support traditional manufacturing are also common.
3DPI: Can you explain the value that LOCTITE 3D resins bring to your platform? How does this complement your existing/ proprietary material portfolio?
LOCTITE has a broad portfolio of prototyping, functional, and specialty materials that address a wide range of applications. Their materials significantly expand the use cases that we are able to serve with our高速打印机。In addition, they respond rapidly to specific customer needs and requirements and can deliver customized materials quickly, which is often essential in manufacturing applications.
3DPI: Have you worked with LOCTITE to develop customized materials? If so, can you describe the collaboration process?
Kevin McAlea: Yes, we recently partnered with Henkel to help a French telemedicine medtech start up, WeMed produce the world’s first additively manufactured connected stethoscope in a matter of weeks. Working with Henkel, we were able to develop suitable color-matched materials in about a month. WeMed was able to proudly showcase this product at this year’s CES Conference. More information on this collaboration can be found这里。
3DPI：哪些Loctite树脂在您的平台上最感兴趣/使用？对为什么这可能是什么见解？
Kevin McAlea: A couple of examples come to mind. A fast, economic general-purpose material that enables robust prototyping and modeling. Also, materials that are engineered to be durable and perform as good or better than thermoplastics like Polypropylene & ABS.
随着客户扩大制造添加性生产的生产零件的扩展，需要缩小差距并达到或超过注入成型的参考标准。大多数性能塑料零件都是在ABS＆PP及其变体中制成的。通过将类似的性能材料与Nexa3d的高吞吐打印机相结合，我们将靠近，在某些情况下超过经济学以及注射模制零件的机械性能。
3DPI：您如何预期利用Loctite树脂的打印机平台将在2022年增长？
凯文·麦卡利亚（Kevin McAlea）：一些利用针对扩大生产零件的定制树脂开发的重点领域包括以下内容。解决特定最终用途要求的专门材料，例如FR和ESD。支持传统制造业的模式和工具，尤其是用于投资铸造。耐用的材料，可抵消PP和ABS，在各种工程组件中具有增强的耐用性和天气性。
