WebJan 24, 2024 · The following are some basic ways in which polymers are classified: 1. Based on occurrence, polymers are classified into natural polymers, synthetic polymers, and semi-synthetic polymers. 2. Based on the structure, polymers are classified into linear polymers, branch chain polymers and cross-linked polymers. 3. WebWarpage and residual stresses are often found in thermally printed parts using polymers as raw materials, leading to a reduction in the appearance and mechanical properties of the parts. Parts made from carbon fibre-reinforced composites, on the other hand, have a much stronger mechanical strength than normal polymers and therefore have a higher quality …
