“…A decrease in mechanical properties was observed in pre-conditioned samples due to the influence of humidity. The ultimate stress values increased over a period of 30 days, following which a decrease was noticed, indicating the onset of degradation following a short initial period of curing [48].…”

Preserving rapid prototypes: a review

et al. 2016

Rapid Prototyping (RP) has revolutionized the world of manufacturing. It has gained popularity among designers and artists, having developed from a visualization tool to a manufacturing tool for end-use products. Rapid-prototyped objects are being accessed by museums and the technology is being adopted for conservation applications. The review identifies the current most commonly used polymer based RP technologies and materials that are likely to enter museum collections, and formulates informed research topics related to their conservation. A knowledge exchange project was conducted with artists and designers using the technology via an online survey and interviews. The main technologies and materials used by artists and designers were identified and investigated including research that has been done into the stability of RP manufactured objects. Since these may be uniquely postprocessed by artists and designers, RP objects are often irreplaceable, i.e. cannot simply be reprinted. The evolution from rapid prototyping (RP) to additive manufacturing (AM) has resulted in extensive research into the mechanical properties and short-term stability of prototypes. However, very little research has been conducted into RP from the conservation perspective particularly long-term stability studies. Since RP technology is rapidly developing, it is crucial that conservators and scientists follow and inform these developments.

“…Anisotropic properties of SLA objects were reported in a study assessing the effects of building orientation on mechanical properties [48]. Using the 3D system Viper si2 SL (with a solid state laser, 354.7 nm) samples were fabricated according to dimensions for ASTM Type I [49] with a photopolymer resin, Watershed tm 11120.…”

“…In the particular case of laser sintering and stereolithography, the process parameters (laser power, layer thickness, speed hatching, etc.) have been shown to influence mechanical properties [4,5]. Kempen [6] also studied the influence of process parameters in selective laser melting (SLM) and various age hardening treatments on the microstructure and mechanical properties of 18Ni-300 steel, showing that this kind of part is almost comparable to those conventionally produced.…”

Standards have to satisfy the needs of the different groups represented, such as industrial, trade, and consumer groups of all of the countries involved. Most experts agree that the lack of additive manufacturing (AM) standards is a key point to take into account in the barriers to broad adoption of AM. Although over the past two decades several entities and groups of experts have demanded the development of specific standards for additive manufacturing, the most important steps forward have been taken in the last few years, mainly through the actions of international organizations such as International Organization for Standardization (ISO) and American Society for Testing and Materials (ASTM), with the support of technical groups and projects focused on the standardization of AM. This work, which is successfully providing new standards for AM, is expected to be reinforced by a global agreement between ASTM and ISO with the aim of collaboration on common AM standards. This paper presents a summary and review of actions carried out so far by different organizations and projects, based on the work of several road maps and workshops, with the aim of developing new standards in this particular field.

The aim of this study was to assess the innovation risk for an additive manufacturing process. The analysis was based on the results of static tensile tests obtained for specimens made of photocured resin. The assessment involved analyzing the measurement uncertainty by applying the FMEA method. The structure of the causes and effects of the discrepancies was illustrated using the Ishikawa diagram. The risk priority numbers were calculated. The uncertainty of the tensile test measurement was determined for three printing orientations. The results suggest that the material used to fabricate the tensile specimens shows clear anisotropy of the properties in relation to the printing direction.
