Additive manufacturing AM is the fabrication of real three-dimensional objects from metals, ceramics, or plastics by adding material, usually as layers. There are several variants of AM; among them material extrusion ME is one of the most versatile and widely used. In MEAM, molten or viscous materials are pushed through an orifice and are selectively deposited as strands to form stacked layers and subsequently a three-dimensional object. The commonly used materials for MEAM are thermoplastic polymers and particulate composites; however, recently innovative formulations of highly-filled polymers HP with metals or ceramics have also been made available. MEAM with HP is an indirect process, which uses sacrificial polymeric binders to shape metallic and ceramic components.

Metal and Ceramic Injection Molding

Based on the s tereolithography for ceramic materials , the new 3D printer was developed for producing high-accuracy dental parts, i. To quickly bring th e new 3D printing technology for ceramic from concept to reality, Lithoz was founded in focusing on intensive development of new materials. A few years later, the new 3D printing approach was successfully tested during European research project ReProMag dedicated to m anufacturing of complex geometries with use of metal powders. With metal powders, Incus took the technology one step further and came up with a way to print high-quality parts made of stainless steel and titanium. The LMM technology enables the production of high-performance parts with the same material properties as parts produced by Metal Injection Molding MIM , a mass production method. LMM can be easily implemented into existing M IM manufacturing processes without the need for any postprocessing machinery or additional expertise, thus enabling a reduction of production costs and time.

Written by Alkaios Bournias Varotsis. Binder Jetting is a family of additive manufacturing processes. In Binder Jetting , a binder is selectively deposited onto the powder bed, bonding these areas together to form a solid part one layer at a time. The materials commonly used in Binder Jetting are metals, sand, and ceramics that come in a granular form. Binder Jetting is used in various applications, including the fabrication of full-color prototypes such as figurines , the production of large sand casting cores and molds and the manufacture of low-cost 3D printed metal parts. With such diverse applications, it is essential for a designer who wants to use the capabilities of Binder Jetting to the fullest, to understand the basic mechanics of the process and how these connect to its key benefits and limitations.

Powder Injection Molding of Metal and Ceramic Parts

The approaches to production of titanium powder injection molded parts are reviewed. Historically, oxygen levels have been too high for structural use particularly with the Ti-6Al-4V alloy.

Feedstock Technology for Reactive Metal Injection Molding

In the s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. One of the key advantages of 3D printing is the ability to produce very complex shapes or geometries that would be otherwise impossible to construct by hand, including hollow parts or parts with internal truss structures to reduce weight. Fused deposition modeling , or FDM, is the most common 3D printing process in use as of [update]. The umbrella term additive manufacturing AM gained popularity in the s, [5] inspired by the theme of material being added together in any of various ways. In contrast, the term subtractive manufacturing appeared as a retronym for the large family of machining processes with material removal as their common process.

The ceramic molding process is a production method which guarantees the precision required, and also gives a good surface finish, using a high temperature method to better structure and shape parts. This process also gives a low grade of toleration. The patterns that ceramic mold uses are plaster , plastic , wood , metal , rubber , etc. The pattern is the shape body of the desired part. Ceramic molding has been around for centuries. When man discovered fire, they got curious of what they could do with the fire, so they experimented with the process of clay and fire, and began the technique known as ceramic molding, or pottery. Archeologists all over the world have discovered hundreds of different types of pottery that have been linked to the history of the place the pottery was found.

Feedstock Technology for Reactive Metal Injection Molding: Process, Design, and Application provides an authoritative guide on the basics of feedstock technology and the latest developments in binders for titanium metal injection moulding and their potential implications. In addition, the book presents challenges that MIM technology of reactive metals is currently facing and potential solutions for commercial success. As both commercial growth and research development are fundamentally driven by the economics of manufacture, this book presents the problems and potential solutions regarding reactive metals, making it a valuable resource for engineers intending to utilize MIM in commercial product design. Researchers and engineers working in materials science. Graduate students and researchers in metallurgy and light alloys. Researchers and engineers in titanium industry. His group at the University of Auckland focuses on developing titanium powder technologies and new energy-storage materials.

In this work, GO was incorporated into phenol formaldehyde PF resin by in situ polymerization. Springer International Publishing AG. Substances in this group were identified as priorities for assessment as they met categorization criteria under subsection 73 1 of CEPA. These eight substances were previously evaluated under the Second Phase of Polymer Rapid Screening, which identified phenol-formaldehyde resins as having low potential to cause ecological harm. The present assessment summarizes the approach applied during the second phase of polymer rapid screening and further elaborates on the potential for phenol-formaldehyde resins to cause harm to human health in order to reach an overall conclusion under section 64 of CEPA as to whether they pose a risk to the environment or human health. Phenol-formaldehyde resins do not occur naturally in the environment but are prepared industrially.
