3D打印在电力行业的应用研究

2014年初Pw C(普华永道)公司进行的相关调查预示着3D打印革命的到来,参加调查的100多家制造企业中,有11%已经大规模采用3D打印技术生产配件或产品。根据盖特纳(Gartner)公司的分析,当一种技术的采用比例达到20%的时候,它就已经成为主流。现在可打印材料除了基本的塑料和感光树脂,还有陶土、水泥、玻璃、多种金属以及合金,乃至加入了碳纳米管和纤维的新型热塑性复合材料。虽然运用新的3D打印方法和新材料往往使得商品直接成本升高,但是增材制造技术带来的高度灵活性可以让总成本降低,加上具有优势的应用模式,成本将进一步的降低。目前,3D打印技术最大的优势就是个性化打印,满足个性化需求,但是随着材料范围的拓宽以及打印速度的加快,3D打印技术将会成井喷方式的发展,尤其是在制造行业和一些服务型行业,本文就在电力行业引入3D打印的应用场景以及可能性,详细从成本、性能、效率三个方面探究,并提出需要注意的事项。

国内3D打印产业化难在哪？

国外很多产品是定制化、个性化的,产量不是很大,可以直接使用3D打印设备进行生产。而中国市场则更喜欢大规模制造生产出来的物美价廉的产品,对定制化、个性化产品的接受程度有限,这在一定程度上制约了3D打印在国内的应用和发展。2013年,武汉滨湖机电技术产业有限公司（以华中科技大学快速制造中心为依托单位）共卖出了30台工业级3D打印机,其中有两台分别出口到了巴西和新加坡。2013年公司营收5000多万元,利润率约10%,均比2012年增长50%左右。不过,对于这样的成绩,该公司的副总经理周刚并不满足。“由于应用市场有限,

3D Printing and Nanotechnology: A Multiscale Alliance in Personalized Medicine

3D printing and nanotechnology have been two important tools in the development of therapeutic approaches for personalized medicine. More recently, their alliance has been improved in an effort to build innovative, versatile, multifunctional, and/or smart medical and pharmaceutical products. Therefore, an extensive review about scientific studies that ally 3D printing and nanomaterials in the development of new approaches for pharmaceutical and medical applications for the treatment and prevention of diseases is presented here. The articles are classified into five categories according to their main application: Cell growth and tissue engineering, antimicrobial, drug delivery, stimulus-response, and theranostics. Semisolid extrusion, inorganic nanoparticles, and cell growth and tissue engineering are the most reported 3D printing technique, type of nanomaterial, and application, respectively. The increase in papers dedicated to these areas is also notable, especially in the 2019 and 2020, when semisolid extrusion became the most used technique, overcoming fused deposition modelling. In fact, this review highlights that the possibility of an alliance between 3D printing and nanotechnology for the production of multiscale materials is undoubtedly a great opportunity for knowledge and innovation in the pharmaceutical and medical area.     

Mechanical Properties Tailoring of 3D Printed Photoresponsive Nanocellulose Composites

3D printing technologies allow control over the alignment of building blocks in synthetic materials, but compositional changes often require complex multimaterial printing steps. Here, 3D printable materials showing locally tunable mechanical properties are produced in a single printing step of Direct Ink Writing. These new inks consist of a polymer matrix bearing biocompatible photoreactive cinnamate derivatives and up to 30 wt% of anisotropic cellulose nanocrystals. The printed materials are mechanically versatile and can undergo further crosslinking upon illumination. When illuminating the material and controlling the irradiation doses, the Young's moduli can be adjusted between 15 and 75 MPa. Moreover, spatially controlled illumination allows patterning stiff geometries, resulting in 3D printed structures with segments of different mechanical properties tailoring the mechanical behavior under compression. The high design freedom implemented by 3D printing and photopatternability opens the venue to rapid manufacturing of devices for applications such as prosthetics or soft robotics where the 3D shapes and mechanical properties must be tailored for personalized load cases.

Stencil‐based 3D facial relief creation from RGBD images for 3D printing

Three‐dimensional (3D) selfie services, one of the major 3D printing services, print 3D models of an individual's face via scanning. However, most of these services require expensive full‐color supporting 3D printers. The high cost of such printers poses a challenge in launching a variety of 3D printing application services. This paper presents a stencil‐based 3D facial relief creation method employing a low‐cost RGBD sensor and a 3D printer. Stencil‐based 3D facial relief is an artwork in which some parts are holes, similar to that in a stencil, and other parts stand out, as in a relief. The proposed method creates a new type of relief by combining the existing stencil techniques and relief techniques. As a result, the 3D printed product resembles a two‐colored object rather than a one‐colored object even when a monochrome 3D printer is used. Unlike existing personalization‐based 3D printing services, the proposed method enables the printing and delivery of products to customers in a short period of time. Experimental results reveal that, compared to existing 3D selfie products printed by monochrome 3D printers, our products have a higher degree of similarity and are more profitable.     

3D Printed Neural Regeneration Devices

Neural regeneration devices interface with the nervous system and can provide flexibility in material choice, implantation without the need for additional surgeries, and the ability to serve as guides augmented with physical, biological (e.g., cellular), and biochemical functionalities. Given the complexity and challenges associated with neural regeneration, a 3D printing approach to the design and manufacturing of neural devices can provide next‐generation opportunities for advanced neural regeneration via the production of anatomically accurate geometries, spatial distributions of cellular components, and incorporation of therapeutic biomolecules. A 3D printing‐based approach offers compatibility with 3D scanning, computer modeling, choice of input material, and increasing control over hierarchical integration. Therefore, a 3D printed implantable platform can ultimately be used to prepare novel biomimetic scaffolds and model complex tissue architectures for clinical implants in order to treat neurological diseases and injuries. Further, the flexibility and specificity offered by 3D printed in vitro platforms have the potential to be a significant foundational breakthrough with broad research implications in cell signaling and drug screening for personalized healthcare. This progress report examines recent advances in 3D printing strategies for neural regeneration as well as insight into how these approaches can be improved in future studies.     

3D Printing Personalized,Photocrosslinkable Hydrogel Wound Dressings for the Treatment of Thermal Burns

Considering the variations in burns depending on the circumstances that caused them, the need for personalized medicine and care for burn victims is vital to ensure that optimal treatment is provided. With the level of accuracy and customization that 3D printing brings as a technology, there is potential in its use to fabricate wound dressings that can provide better treatment for burn patients, provided that the material of choice has good printability and can be customized while facilitating wound healing. In this study, the versatility of chitosan methacrylate as said material to be used to fabricate customizable wound dressings via 3D printing is investigated. Synthesized chitosan methacrylate is evaluated to be printable, biodegradable, and biocompatible during wound healing. Various drugs relevant to the treatment of burns are then loaded and different multimaterial wound dressing designs containing different dosages are fabricated via 3D printing. The incorporation of said drugs does not significantly affect the printability of chitosan methacrylate, and the incorporation of antimicrobial agents significantly improves its antimicrobial capabilities. Through in vivo models, these variations in wound dressing designs have good wound healing properties and do not cause any adverse effects in the process.
