Size Effects on the Mechanical Properties of 3D Printed Plaster and PLA Parts

It is common to perform small-scale prototyping before large-scale application of three-dimensional (3D) printing technology and in this case size effects can have an important effect. There has been limited study to date on the size effects associated with 3D printing technology. Plaster and polylactic acid (PLA) were selected as typical inorganic and organic 3D printing materials. Binder jetting was used to print cube plaster specimens for...
