why do polymers have low melting points

ABSTRACT: Empirically validating new 3D-printing related algorithms and implementations requires testing data representative of inputs encountered emph{in the wild}. An ideal benchmarking dataset should not only draw from the same distribution of shapes people print in terms of class (e. g. , toys, mechanisms, jewelry), representation type (e. g. , triangle soup meshes) and complexity (e. g. , number of facets), but should also capture problems and artifacts endemic to 3D printing models (e. g. , self-intersections, non-manifoldness). We observe that the contextual and geometric characteristics of 3D printing models differ significantly from those used for computer graphics applications, not to mention standard models (e. g. , Stanford bunny, Armadillo, Fertility).

We present a new dataset of 10,000 models collected from an online 3D printing model-sharing database. Via analysis of both geometric (e. g. , triangle aspect ratios, manifoldness) and contextual (e. g. , licenses, tags, classes) characteristics, we demonstrate that this dataset represents a more concise summary of real-world models used for 3D printing compared to existing datasets. To facilitate future research endeavors, we also present an online query interface to select subsets of the dataset according to project-specific characteristics. The complete dataset and per-model statistical data are freely available to the public.
This polymer has a melting point of only 60`C, which means it can be shaped by hand after a few minutes in hot water.

PCL can be reheated and reshaped again and again. It feels like nylon when hardened. Used for: Polycaprolactone (PCL) is originally an industrial polymer with applications in, for example, hot-melt glue and laminating pouches. It is also used for model making and prototyping. It can be used to make moulds for reproduction. It is also used for jewelry making under the brand name Friendly Plastic. Details: PCL is non-hazardous and biodegradable; it can be coloured with fruit colours. Typical modulus of elasticity is ~440 MPa and tensile strength is ~16 MPa. PCL is resistant to water, oil, solvent, and chlorine.

Polycaprolactone is also sold under the namesPShapelock (US), Polymorph (UK), Instamorph, PlastiMake (AUS) and Friendly Plastic. The material is delivered as granules that can be easily melted in hot water and shaped. PWe can sell any quantity, so pleaseP if you need larger quantities or have questions. All samples come with a laminated. Polycaprolactone as sheets and mesh: We are now also stocking polycaprolactone in the form of mesh and sheets. See the products. A new variant: We also supply that melts at just 42`C. You have longer time to shape this material before it hardens and it is not as hot to touch when melted.
