Interest in motion picture studies has grown rapidly over the past dozen years. A logical consequence of this interest has been the development of several retrospective and current indexes devoted to various aspects of film whether as an art form or as a business. Some of these sources have filled gaps in the field, while others, claiming to do so, have not. The computer also deserves some recognition fo: its role in the development of some of these publications. The 1970s have been a particularly active period in the publication of film studies indexes.

This paper aims to study the effects of part orientation during the 3D printing process, particularly to the case of using continuous digital light processing (cDLP) technology.

The effects of print orientation on the print accuracy of microstructural features were assessed using microCT imaging and mechanical properties of cDLP microporous scaffolds were characterized under simple compression and complex biaxial loading. Resin viscosity was also quantified to incorporate this factor in the printing discussion.

The combined effect of print resin viscosity and the orientation and spacing of pores within the structure alters how uncrosslinked resin flows within the construct during cDLP printing. Microstructural features in horizontally printed structures exhibited greater agreement to the design dimensions than vertically printed constructs. While cDLP technologies have the potential to produce mechanically isotropic solid constructs because of bond homogeneity, the effect of print orientation on microstructural feature sizes can result in structurally anisotropic porous constructs.

This work is useful to elucidate on the specific capabilities of 3D printing cDLP technology. The orientation of the part can be used to optimize the printing process, directly altering parameters such as the supporting structures required, print time, layering, shrinkage or surface roughness. This study further detailed the effects on the mechanical properties and the print accuracy of the printed scaffolds.

The emphasis of this survey is on motion picture reference material that has been published since 1982. This update does not, for the most part, include titles covered in a prior RSR article (1:4; 1983), written by myself, or in an even earlier article by Leslie Kane (7:1; 1979). In those few instances where titles that have appeared in the earlier RSR film surveys are discussed, it is because they now have a new subject emphasis.

This index accompanies the index that appeared in Reference Services Review 16:4 (1988). As noted in the introduction to that index, the articles in RSR that deal with specific reference titles can be grouped into two categories: those that review specific titles (to a maximum of three) and those that review titles pertinent to a specific subject or discipline. The index in RSR 16:4 covered the first category; it indexed, by title, all titles that had been reviewed in the “Reference Serials” and the “Landmarks of Reference” columns, as well as selected titles from the “Indexes and Indexers,” “Government Publications,” and “Special Feature” columns of the journal.

The aim of this paper is to examine the effects of light controlling system that combined high refractive particles (n-TiO₂ [titanium dioxide – TiO₂]) and tartrazine lake dye (TL dye) on thickness, flexural strength, flexural modulus and surface details of the 3D-printed resin.

Influences of different concentrations of n-TiO₂ and TL dye in light-cured resin formulations for 3D printing (3DP) application were evaluated, including curing thickness, flexural strength and surface details under scanning electron microscopy.

The polymerization thickness of samples containing both n-TiO₂ and TL dye was lower compared to samples with TL dye solely. Samples containing more n-TiO₂ and more TL dye exhibited lower flexural strength and modulus. Ramp models showed that for samples containing 1 per cent TL dye, when their n-TiO₂ content increased from 1 to 5 per cent, surface laminate structures became sharper. However, when the TL dye content doubled to 2 per cent, the surface laminate structures were indefinite compared to 1 per cent TL dye-containing counterparts.

In visible-light 3DP, light controlling system in cooperate dye with high refractive particles provides better energy distribution and scattering control. High refractive particles, dyes and light exposure time had influenced the surface resolution and mechanical properties of the 3DP products.
