Influence of the Resin System and Sand Type on the Infiltration of 3D-Printed Sand Tools.

Binder jetting is a highly productive additive manufacturing (AM) method for porous parts. Due to its cost-effectiveness, it is used for large components and quantities ranging from prototyping to series production. Post-processing steps like sintering or infiltration are common in several applications to achieve high density and strength.

Functional Analysis in Public School Settings: A Systematic Review of the Literature.

Previous studies have shown that variations of experimental functional analysis (FA) can be used effectively as part of the functional behavioral assessment process in educational settings. The purpose of the current study was to review the literature pertaining to FA of problem behavior in schools focusing on method, topographies, and results. Results of this review showed that analog functional analysis (AFA) are conducted most often in school settings; but recent trends show that use of adapted formats (e.

Characterization of Slurry-Cast Layer Compounds for 3D Printing of High Strength Casting Cores.

Additive manufacturing of casting cores and molds is state of the art in industrial application today. However, improving the properties of chemically bonded casting cores regarding temperature stability, bending strength, and surface quality is still a major challenge. The process of slurry-based 3D printing allows the fabrication of dense structures and therefore sinterable casting cores.

3D Printed Sand Tools for Thermoforming Applications of Carbon Fiber Reinforced Composites-A Perspective.

Tooling, especially for prototyping or small series, may prove to be very costly. Further, prototyping of fiber reinforced thermoplastic shell structures may rely on time-consuming manual efforts. This perspective paper discusses the idea of fabricating tools at reduced time and cost compared to conventional machining-based methods.
