我们往往不会在3D打印媒体网络上以第一人称写文章，但是，在这种情况下，我将例外，因为我正在撰写我的最新项目：关于鞋类增材制造的最新研究报告，刚刚由SmarTech Analysis发布。在这份新的鞋类AM 2020报告中，我研究了用于鞋类系列，批量和批量定制生产的增材制造的硬件技术，新材料和新应用方面的最新趋势。
We tend not to write articles in the first person on 3D Printing Media Network, however, I will make an exception in this case, as I’m writing about my latest project: the new edition of my study on footwear additive manufacturing, which was just published by SmarTech Analysis. In this new footwear AM 2020 report, I looked at the latest trends in terms of hardware technologies, new materials and new applications of additive manufacturing for footwear serial, mass and mass customized production.
多亏了一些了不起的公司和设计师（Voxel8，voxeljet，ECCO / Quant-U，Prodways，Kings3D和鞋类设计师Nolan Kim以及其他许多人）的贡献，我发现一个细分市场非常活跃，充满严肃和具有商业用途的中底，鞋垫和鞋面AM应用，使我预测到2030年，整个市场的年收入（包括所有AM硬件，材料和应用）将接近90亿美元。
Thanks to contributions from some amazing companies and designers (Voxel8, voxeljet, ECCO/Quant-U, Prodways, Kings3D, and footwear designer Nolan Kim above all but many others as well), I found a segment that is extremely dynamic, with serious and commercially ready AM applications in midsoles, insoles and uppers, that have led me to forecast a total market that could near $9 billion in yearly revenues (including all AM hardware, materials and applications) by 2030.
These contributions, together with extensive research, helped to further evolve my forecast mode, which I had already developed for the previous edition of this report (published just a little over a year ago). That first edition already went a long way into describing the market, its technological and some of its geographic trends. But a lot has happened since – even more than I had initially expected – and this new report reflects a much more “practical” and sustainable approach by many stakeholders in the AM and in the footwear segment.
In the report I provided a deep dive into the revenue opportunities offered by the global footwear segment, reflecting advances where 3D printing is impacting footwear production: prototyping, tooling and final parts. I also include an updated analysis of how AM hardware, AM materials, AM service and AM software are impacted by the evolving footwear industry scenario.
已识别和分类了该细分市场中的所有关键运营商，分析了所有主要技术和所有增材制造材料类别在鞋类零件生产方面的潜力，以便从各个角度评估相关的收入机会。在这些文件中，我介绍了参与3D打印鞋类革命的主要制造商，包括（但不限于）：Carbon，voxeljet，HP，Voxel8，Kings3D，Formlabs，Stratasys，3D Systems，EOS，Prodways，BASF，ECCO，德国RepRap ，阿迪达斯，耐克，锐步，新百伦，Under Armour和Timberland。为了提供这种最新的市场情况，我对许多重要的市场创新者进行了广泛的采访。
All key operators in this segment have been identified and classified, all major technologies and all AM material classes have been analyzed for their potential on footwear part production in order to assess the associated revenue opportunities from all angles. Among these, I profiled the key manufacturers involved in the 3D printed footwear revolution including (and not limited to): Carbon, voxeljet, HP, Voxel8, Kings3D, Formlabs, Stratasys, 3D Systems, EOS, Prodways, BASF, ECCO, German RepRap, Adidas, Nike, Reebok, New Balance, Under Armour, Timberland. I conducted extensive interviews with many of these key market innovators in order to provide this most up-to-date market scenario.
Voxeljet’s upcoming VX1000 HSS system – a massive planar PBF machine – will be able to serially manufacture footwear midsoles using the company’s Greyscale technology.
WIthin the expected $9 billion revenues generated yearly by 2030, applications, in general, are the main revenue generation opportunity, with end-use parts representing nearly half of all footwear AM associated revenues by 2030. In a consumer business segment, applications have the opportunity to truly scale, if hardware will be able to support higher productivity. Photopolymerization – such as that used by Carbon and adidas on midsoles, but also for many tooling and molding applications – remains the most relevant AM technology in the footwear industry and is expected to remain so for the foreseeable future and thus the entire forecast period. The reason why photopolymerization is so dominant in this segment is that it offers several different technological alternatives which cater to multiple key footwear applications.
The improved ability to effectively 3D print thermosets by extrusion technology may be one of the most significant new trends that have emerged and consolidated over the past year. However, as we saw in the previous chapter, the market for footwear AM is still—and is expected to continue to be—very much dependent on industrial vat photopolymerization and polymer powder bed fusion technologies. In both cases, the key materials for end-use applications are modified polyurethanes. In powder bed fusion the most widely used material is expected to be thermoplastic polyurethane (TPU).
ECCO’s Quant-U approach uses silicon material extrusion for 3D printing midsoles in specially developed products with a hollow-core, using relatively standard inlay soles.
Market dynamics for AM production via external 3D printing service providers in the footwear segment are constantly evolving. In the beginning—when the segment was almost entirely concentrated on custom insoles production, specialized “application-agnostic” AM service providers proved to be the primary solution for production requirements as they possessed the knowledge and the machine park to meet small-batch mass customization demands.
最后，尽管3D打印鞋类具有巨大潜力，但仍然存在挑战。 这项业务有可能实现大批量生产，但是这一事实也导致了“未来的制鞋厂”对自动化的需求。 同样重要的是，需要充分利用AM技术带来的几何和性能优势。 这可能会涉及使用高级CAD / CAE软件。 现在有可能为中底设计出优化的点阵结构，这种结构只有通过3D打印才能有效地产生。 现在，生产团队可以在现场快速创建原型以提供即时反馈，从而大大简化了概念创建过程。 增材制造正在改变鞋类的整体设计过程。
Finally, despite the considerable potential for 3D-printed footwear, there remain challenges. High volumes are possible in this business, but this fact also creates a need for automation in the “shoe factory of the future.” Also important is the need to fully exploit the geometric and performance benefits enabled by AM technologies. This will potentially involve the use of advanced CAD/CAE software. It is now possible to design optimized lattice structures for midsoles that can be effectively produced only by 3D printing. Now, production teams can create prototypes rapidly on-site for instant feedback, significantly streamlining the concept creation process. Additive manufacturing is transforming the overall design process for footwear.
