  2. Topology optimization - Wikipedia

    en.wikipedia.org/wiki/Topology_optimization

    Adding constraints to the formulation in order to increase the manufacturability is an active field of research. In some cases results from topology optimization can be directly manufactured using additive manufacturing ; topology optimization is thus a key part of design for additive manufacturing .

  3. 3D printing - Wikipedia

    en.wikipedia.org/wiki/3D_printing

    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.

  4. 3D printing processes - Wikipedia

    en.wikipedia.org/wiki/3D_printing_processes

    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.

  5. Digital modeling and fabrication - Wikipedia

    en.wikipedia.org/wiki/Digital_modeling_and...

    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 ...

  6. Multi-material 3D printing - Wikipedia

    en.wikipedia.org/wiki/Multi-material_3D_printing

    An example of how 3D printing can be included in the design process is automotive design. [19] There, it is necessary to quickly test and verify a prototype to get the design approved for production. The reduced post-processing steps induced by the multi-material 3D printing technology result in a shorter fabrication time.

  7. Design for additive manufacturing - Wikipedia

    en.wikipedia.org/wiki/Design_for_Additive...

    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.

  8. Health and safety hazards of 3D printing - Wikipedia

    en.wikipedia.org/wiki/Health_and_safety_hazards...

    Research on the health and safety hazards of 3D printing is new and in development due to the recent proliferation of 3D printing devices. In 2017, the European Agency for Safety and Health at Work has published a discussion paper on the processes and materials involved in 3D printing, potential implications of this technology for occupational safety and health and avenues for controlling ...

  9. Applications of 3D printing - Wikipedia

    en.wikipedia.org/wiki/Applications_of_3D_printing

    In cars, trucks, and aircraft, additive manufacturing is beginning to transform both unibody and fuselage design and production, and powertrain design and production. For example, General Electric uses high-end 3D printers to build parts for turbines. Many of these systems are used for rapid prototyping before mass production methods are employed.
