Ian Gibson (born 7 April 1963) is a Professor of Design Engineering at the University of Twente. Gibson was selected as the scientific director of Fraunhofer Project Center at the University of Twente [ 1 ] [ 2 ] and is a recipient of lifetime achievement award, the Freeform and Additive Manufacturing Award.
Design for additive manufacturing (DfAM or DFAM) is design for manufacturability as applied to additive manufacturing (AM). It is a general type of design methods or tools whereby functional performance and/or other key product life-cycle considerations such as manufacturability, reliability, and cost can be optimized subjected to the capabilities of additive manufacturing technologies.
Figure 1. 30 cm x 30 cm x 1.2 m object created via HARP. Taken from Ref. [1]. Figure 2. Schematic for 3D printing using HARP. Taken from Ref. [1]. High-area rapid printing (HARP) is a stereolithography (SLA) method that permits the continuous, high-throughput printing of large objects at rapid speeds (Figure 1). [1]
Computer-Aided Design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
Digital modeling and fabrication is a design and production process that combines 3D modeling or computing-aided design (CAD) with additive and subtractive manufacturing. Additive manufacturing is also known as 3D printing, while subtractive manufacturing may also be referred to as machining, [1] and many other technologies can be exploited to ...
