“…[16] For instance, spongiosa-like structures could be easily created out of patient-data. [17] In addition, there are new resins commercially available that may be of interest. They are especially used for close-tomarket prototypes with the touch and look of thermoplastic materials like poly(propylene) (PP), acrylnitrile/ butadiene/styrene (ABS) and polycarbonate (PC).…”

“…Then, the photo-polymerization capability, storage modulus, and bending strength of each mixing condition were compared. The strength of the UDMA (87 Mpa) came close to that of natural bone (100-150 Mpa) (23). Cell adhesion and proliferation of MG63 osteoblast-like cells were evaluated on the material to determine its biocompatibility.…”

The development of scaffolds for use in cell-based therapies to repair damaged bone tissue has become a critical component in the field of bone tissue engineering. However, design of scaffolds using conventional fabrication techniques has limited further advancement, due to a lack of the required precision and reproducibility. To overcome these constraints, bone tissue engineers have focused on solid free-form fabrication (SFF) techniques to generate porous, fully interconnected scaffolds for bone tissue engineering applications. This paper reviews the potential application of SFF fabrication technologies for bone tissue engineering with respect to scaffold fabrication. In the near future, bone scaffolds made using SFF apparatus should become effective therapies for bone defects.

“…Cotteleer 2014) due to the poor stability of mechanical properties over time and relatively high cost; a result of high cost of materials and low production speed (Hague, Mansour, and Saleh 2004;Kim and Oh 2008), despite offering very high resolution, accuracy and surface finish. A possible explanation could be the development of new materials that are better able to approximate the mechanical properties of engineering polymers (Huang, Weng, and Sun 2011;Jardini et al 2006;Rubber 2003;Schuster et al 2007;Zhang, Jin, and Zhao 2013).…”

Additive Manufacturing (AM) technologies are widely adopted in design practice for prototyping. However, the extent to which practitioners are knowledgeable and experienced in designing components for series production using AM remains poorly understood. This study presents the results of an online survey aimed at uncovering this emerging design activity, with additional evidence provided by semi-structured interviews with 18 designers. One hundred ten practising designers responded. The majority of the respondents remain sceptical about the potential for AM as a process for series production, citing cost and technical capabilities as key barriers. Only 23 reported experience in designing components for series production using AM, with the majority of these designing parts to be produced from plastic. The survey revealed that these designers have developed their own 'design rules' based primarily on personal experience. These rules, however, tended to focus on ensuring 'printability' and did not provide support for taking advantage of the unique capabilities of AM processes. The designers tended to treat AM processes as a uniform set of production processes, and so the design rules they used were generic and not directed to the capabilities of specific AM processes.
