“…Since then, LOM has been used with various thermoplastics including PMMA and PC as well as polymer-based composites. For instance, LOM has been used to build free-standing objects from continuous fiber reinforced epoxy resins. − Sun et al reported on the development of a LOM process enabling the fabrication of PC/PMMA-based microchips for lab-on-a-chip immunoassays …”

Additive manufacturing (AM) alias 3D printing translates computer-aided design (CAD) virtual 3D models into physical objects. By digital slicing of CAD, 3D scan, or tomography data, AM builds objects layer by layer without the need for molds or machining. AM enables decentralized fabrication of customized objects on demand by exploiting digital information storage and retrieval via the Internet. The ongoing transition from rapid prototyping to rapid manufacturing prompts new challenges for mechanical engineers and materials scientists alike. Because polymers are by far the most utilized class of materials for AM, this Review focuses on polymer processing and the development of polymers and advanced polymer systems specifically for AM. AM techniques covered include vat photopolymerization (stereolithography), powder bed fusion (SLS), material and binder jetting (inkjet and aerosol 3D printing), sheet lamination (LOM), extrusion (FDM, 3D dispensing, 3D fiber deposition, and 3D plotting), and 3D bioprinting. The range of polymers used in AM encompasses thermoplastics, thermosets, elastomers, hydrogels, functional polymers, polymer blends, composites, and biological systems. Aspects of polymer design, additives, and processing parameters as they relate to enhancing build speed and improving accuracy, functionality, surface finish, stability, mechanical properties, and porosity are addressed. Selected applications demonstrate how polymer-based AM is being exploited in lightweight engineering, architecture, food processing, optics, energy technology, dentistry, drug delivery, and personalized medicine. Unparalleled by metals and ceramics, polymer-based AM plays a key role in the emerging AM of advanced multifunctional and multimaterial systems including living biological systems as well as life-like synthetic systems.

“…While the strength of the nonreinforced object was relatively constant, the strength of the reinforced object varied strongly. An attempt to embed fibers into a laminated object manufacturing (LOM) process using continuous fiber ceramic matrix composites (CMCs), and short fiber CMCs was performed in [61]. The layers finally had a thickness of 230 to 260 µm and a relatively high fiber content compared to the FDM process as described above of approximately 50%.…”

“…Although most widely used for relatively simple shapes with low demands as to precision, advanced slip casting with fugitive mold techniques can also be employed for complex shapes such as gas-turbine rotors. 99 In order to achieve good particle dispersion, slip casting requires thorough control of characteristics such as pH, viscosity, and addition of steric stabilizers. As it is necessary to manufacture optimized molds, slip casting is of limited value for prototyping.…”
