Abstract
Objects can be produced using an additive manufacturing process and the objects can be removed from the substrates on which the objects are formed. An object can include a plurality of layers of a polymeric material that includes units of a diacid component and units of a glycol component. A process can be used to form the object that includes depositing a plurality of layers of the polymeric material onto a substrate to form the object. In some cases, the plurality of layers are deposited onto the substrate according to a predetermined design.
Claims17
An article comprising:
- a plurality of layers of a polymeric material that includes units of a diacid component and units of a glycol component, wherein the units of the diacid component are derived from a first diacid and a second diacid.
An article comprising:
- a body comprised of a polymeric material that includes units of a diacid component and units of a glycol component, wherein:
- the body has a diameter from about 1 mm to about 5 mm and a length of at least about 3 cm;
- and
- an inherent viscosity loss of an object formed from the polymeric material relative to the polymeric material before forming the object is no greater than about 0.9%.
