Pacific Northwest. What is Additive Manufacturing?. (AM), . n—. a process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies. Synonyms: additive processes, additive techniques, additive layer manufacturing, layer manufacturing, and freeform fabrication.. C2: Chapter 2. Learning Objectives. To be able to . list. and . state. uses of commonly used polymers. To be able to . recall and describe. the conditions required for the production of LDPE, HDPE, thermosetting and thermosoftening polymers. Polymers. . C.X.C objectives. Students should be able to :. Define polymers. Distinguish between addition and condensation as reactions in the formation of polymers. Name examples of polymers formed by:. AND . POLYMERIZATION. By. Dr Rashid Hassan. Assistant Professor. RIHS. ISLAMABAD. 1. POLYMER. Poly = Many mer = Units. I.e. a material made up of many units.. Properly defined as:. Chemical compound composed of large organic molecules formed by the union of many repeating small monomer units.. Carbohydrates, lipids, proteins, and nucleic acids. Monomers. Glucose. Amino acids. Nucleotides . Fatty acids . Polymers. Carbohydrates . Nucleic acids. Lipids . Proteins . Carbohydrates. The word carbohydrate literally means “watered carbon.”. Polymers. are long molecules made of repeating units, called . monomers. .. In general. :. Specific example. :. Forces between polymer chains: Crosslinks. Weak: Intermolecular . force crosslinks. Strong: Colvalent. Welcome. "Opportunities for Additive Manufacturing in DoD & NASA Acquisition", . John Rice, DAU. . Additive Manufacturing Library, . Alberto . Lacaze. , Robotics Research. VeriPart. Tool and Block-Chain, . D 15. Explain the general formation and structure of carbon-based polymers, including synthetic polymers, such as polyethylene, and biopolymers, such as carbohydrate. . Content Standard . What is a monomer and what is a polymer?. Phenomenon:. . experiment by pouring the gel. Have you ever seen anything that acts like this gel?. What is happening to the molecules to make it act this way?. Show the beads in the jar and how they will keep falling out after you start them.. Steering and Working Groups. (JAMSG/JAMWG). update. 4 October 2017. Tracy Frost. Director, Manufacturing Technologies (ManTech) and DoD Manufacturing USA Institutes. Manufacturing and Industrial Base Policy (MIBP) . Workshop. 23 – 25 June. Virtual . Greg Kilchenstein (ODASD Materiel Readiness). Kelly Visconti (OUSD Research & Engineering). Marilyn . Gaska. (America Makes / Lockheed Martin). 1. 2. June 25 (Day 3). → . the . synthesis of new polymers by modification of existing . polymers using . a variety of chemical . reactions. 1) . the esterification of cellulose, crosslinking of . polyisoprene. , hydrolysis. What are Additives?. Additives are substances put into food during processing in order to improve it in some way. . They may be natural, e.g. spices or herbs, or artificial, e.g. tartrazine, which is a yellow colour in sweets and soft drinks..
