Additive Manufacturing of Metals: The Technology, Materials, Design and Production (Springer Series in Advanced Manufacturing)

This book offers a unique guide to the three-dimensional (3D) printing of metals. It covers various aspects of additive, subtractive, and joining processes used to form three-dimensional parts with applications ranging from prototyping to production.

 Examining a variety of manufacturing technologies and their ability to produce both prototypes and functional production-quality parts, the individual chapters address metal components and discuss some of the important research challenges associated with the use of these technologies.

 As well as exploring the latest technologies currently under development, the book features unique sections on electron beam melting technology, material lifting, and the importance this science has in the engineering context. Presenting unique real-life case studies from industry, this book is also the first to offer the perspective of engineers who work in the field of aerospace and transportation systems, and who design components and manufacturing networks. Written by the leading experts in this field at universities and in industry, it provides a comprehensive textbook for students and an invaluable guide for practitioners

Perstorp AB creates 3D printer materials venture with 3D4Makers

Perstorp AB, a world leading specialty chemicals company, and 3D printing filament producer 3D4Makers have joined forces to create Netherlands based company ‘ElogioAM’ a new material production venture.

Combining the knowledge of chemicals and polymers, ElogioAM is introducing Facilan, a strong and compostable filament for FDM/FFF 3D printing. 

Stamping out common 3D printing issues

User reported issues detail problems with layer adhesion, warping, surface quality and misprints which limits printability of existing filaments. Perstorp AB and 3D4Makers designed Facilan fit-for-purpose filaments to remedy such issues through a wide range of medical and manufacturing products. The companies collaborated as a result of their shared ambition to create a new generation of materials for the 3D printing industry.

“It is all about chemistry and engineering at their best, and for satisfying today’s demand for more reliable FDM [Fused Deposition Modeling] 3D printing quality,” said David James, Vice President of Perstorp AB.

Comprised of three materials, the Facilan filaments are compostable bioplastic FDM grades that have a higher impact and tensile strength when compared to ABS filaments. Additionally, Facilan parts offer a smoother texture as opposed to PLA and ABS parts.

Expanding applications

ElogioAM aims to improve Additive Manufacturing capabilities through their products in various industries and consumer markets such as medical, fashion, orthotics, advanced prototyping, and modeling.

Jan-Peter Wille, Co-Founder of 3D4Makers states, “We’re very proud to be working together with Perstorp, their specialty chemicals, additives and polymer knowledge has really made materials in 3D printing possible that we could only dream of.”

3D4Makers previously developed a stronger filament without the use of water that is now less prone to break or crack.

“Better tolerance materials and higher performance parts is what really will put 3D printing on the factory floor and in most cutting-edge applications. Perstorp is quick, flexible and innovative; giving us a partner cable of innovating continuously in the dynamic 3D printing market. ElogioAm is a very exciting development for us and we would like to thank our partners for their trust, ” Wille adds.

Researchers are currently developing a pure polycaprolactone filament, Facilan PCL 100, to be used in artificial muscles, drug-loaded implants, scaffolds and smart materials.

Modeling and Simulation of Functionalized Materials for Additive Manufacturing and 3D Printing: Continuous and Discrete Media: Continuum and Discrete … Notes in Applied and Computational Mechanics)

Within the last decade, several industrialized countries have stressed the importance of advanced manufacturing to their economies. Many of these plans have highlighted the development of additive manufacturing techniques, such as 3D printing which, as of 2018, are still in their infancy. The objective is to develop superior products, produced at lower overall operational costs. For these goals to be realized, a deep understanding of the essential ingredients comprising the materials involved in additive manufacturing is needed. The combination of rigorous material modeling theories, coupled with the dramatic increase of computational power can potentially play a significant role in the analysis, control, and design of many emerging additive manufacturing processes. Specialized materials and the precise design of their properties are key factors in the processes. Specifically, particle-functionalized materials play a central role in this field, in three main regimes:

 (1) to enhance overall filament-based material properties, by embedding particles within a binder, which is then passed through a heating element and the deposited onto a surface,

 (2) to “functionalize” inks by adding particles to freely flowing solvents forming a mixture, which is then deposited onto a surface and

 (3) to directly deposit particles, as dry powders, onto surfaces and then to heat them with a laser, e-beam or other external source, in order to fuse them into place.

The goal of these processes is primarily to build surface structures which are extremely difficult to construct using classical manufacturing methods. The objective of this monograph is introduce the readers to basic techniques which can allow them to rapidly develop and analyze particulate-based materials needed in such additive manufacturing processes. This monograph is broken into two main parts: “Continuum Method” (CM) approaches and “Discrete Element Method” (DEM) approaches. The materials associated with methods (1) and (2) are closely related types of continua (particles embedded in a continuous binder) and are treated using continuum approaches. The materials in method (3), which are of a discrete particulate character, are analyzed using discrete element methods.
