The invention relates, among other things, to a method of making a thin panel (10) for outdoor applications, comprising, among other things, the following steps: a) providing a deep-drawable film (10) of a transparent plastic, b) deep-drawing the film (11) in a mold (34), c) mounting a structure (19) having solar cells (32) on an inner face (16) of the deep-drawn film (12), d) placing the deep-drawn film (12) with mounted structure (19) in a cavity (33) of a mold (34) having in particular at least two mold halves (13, 14), e) introducing a liquid polyurethane casting compound (24) into the cavity (33) of the mold (34) and spreading the polyurethane casting compound (24) over an inner face (18) of the structure (19) and/or over the inner face (16) of the film (12), f) curing the polyurethane casting compound, in particular with the mold closed, to form a reinforcement layer (30), or comprising the following steps j) and k) instead of the steps e) and f): j) introducing a granular particle foam mass into the cavity (33) of the mold (34) and spreading over an inner face (18) of the structure (19) and/or over the inner face (16) of the film (12), k) baking and curing the particle foam mass, in particular with the mold closed, to form a reinforcement layer (30).

Additively manufactured structure and method for making the same

An additively manufactured structure and methods for making and using same. An object can be printed at least partially on an attachment portion. The attachment portion can be bonded to the object upon the printing. The object does not need to be removed from the attachment portion. The need of providing a print surface to allow easy removal of the object is eliminated. The object can be a flat panel and can eliminate the need of printing a large flat layer using additive manufacturing. The attachment portion can be cut prior to the printing, so no trimming needs to be performed after the printing. The attachment portion can be made of a material that has one or more selected properties to expand functionalities of the object. A secondary operation for attaching the attachment portion to the object after the printing can be eliminated.
