plaster casting

plaster casting,

as a sculpture process, is of three kinds. One employs a waste mold, another a piece mold (both plaster of paris), and the third a gelatin mold; all reproduce the original clay or wax model executed by the sculptor. The waste mold is chipped away (wasted) to free the hardened cast, which was poured in as liquid plaster. The gelatin mold, being pliable, may with care be sprung from the cast and removed intact and used for replicas. The piece mold also may be used again, being so divided as to be readily drawn away from the undercutting of the cast without damage to either. Plaster casts are used not only for the creation of new sculptures, but also for the numerous replicas of famous marble or stone statues. The ancient Egyptians used models of plaster taken directly from the human body. The Romans cast in plaster many thousands of copies of Greek statues. In another sense of the term, plaster casting refers to the surgical technique of encasing in a plaster-of-Paris cast any part of the body in which bones are broken so that the bones may set smoothly without interference by motion, jarring, or physical shock.

Conclusion; Ponseti method of manipulation and plaster casting is very effective in correcting clubfoot deformity.
Objective: To compare the outcomes of plaster casting and external fixation in comminuted distal radius fractures.
With "Cast From Nature"--which has been mounted in a new version at the Camden Arts Center in London--Borland expanded her practice, developing theatrical settings with herself as a performer, and learning historical methods of mold making and plaster casting. Through this rigorous process, she astutely reanimated an anonymous and forgotten figure, transforming it into something universal and contemporary, and triumphantly restoring a sense of its humanity.
Plaster casting often serves as a precursor to diecasting production while the hard tool is being made.

The authors also conducted a randomized trial to compare treatment with either plaster casting or immobilization splinting.
"For the first time ever, we measured shape change through imaging -- without having to go through plaster casting." Vannier explains.
The 48 to 72 hour drying time typically required for plaster casts, during which the cast must be left uncovered and handled with care to prevent indentation, is a major drawback of plaster casting. This is especially trying for the young active age groups, in which most fractures and casting are occurring.
Johnson then consolidated several plaster casting processes from other firms and partnered with a gypsum company to develop an aerating plaster that could be used as a mold material.
This transformative capacity of plaster casting occasionally shares in a certain anthropomorphism (a defect the orthodoxly Modernist Michael Fried thought could be detected in Minimalist sculpture, in the work of both Tony Smith and Robert Morris, for example, without considering to what extent this trait could reflect decidedly different esthetics in each case).
Rapid prototyping techniques in combination with plaster casting, a process that has been around a long time, offers a fast and inexpensive way to create prototypes of diecast parts as illustrated in Fig.
