The present disclosure relates a method of 3-dimensional printing a printed part. The method comprises printing an inkjet dopant composition at selected locations on a layer of build material comprising polymer particles. The inkjet dopant composition comprises a dopant dispersed or dissolved in a liquid carrier. Polymer particles at selected areas of the layer of build material are then fused to form a fused polymer layer comprising the dopant. The selected areas of the layer of build material include areas of the layer of build material that have not been printed with the inkjet dopant composition.

An approach to improving optical scanning increases the strength of optical reflection from the build material during fabrication. In some examples, the approach makes use of an additive (or a combination of multiple additives) that increases the received signal strength and/or improves the received signal-to-noise ratio in optical scanning for industrial metrology. Elements not naturally present in the material are introduced in the additives in order to increase fluorescence, scattering or luminescence. Such additives may include one or more of: small molecules, polymers, peptides, proteins, metal or semiconductive nanoparticles, and silicate nanoparticles.

Imprint method and apparatus apply an imprint material on a substrate. The imprint material includes a luminescent material that undergoes fluorescence or phosphorescence upon receiving ultraviolet light. The imprint material further includes an ultraviolet curable resin that is cured with ultraviolet light. A mold with a pattern imprints into the imprint material applied to the substrate. The imprint material applied to the substrate is cured with ultraviolet light. After releasing the mold from the substrate imprinted with the pattern, any residual resin remaining on the mold can be detected with ultraviolet light.

Described is a peelable heat shrink tube composed of a fluororesin and having a determination coefficient calculated from [Equation 1] below using an elastic modulus ratio (%) of more than 0, but 0.90 or less: $\begin{array}{cc}\mathrm{Determination}\mathrm{coefficient}={\left(\mathrm{correlation}\mathrm{coefficient}\right)}^2={\left[\frac{\left(\mathrm{covariance}\right)}{\left(\mathrm{standard}\mathrm{deviation}\mathrm{of}X\right)\left(\mathrm{standard}\mathrm{deviation}\mathrm{of}Y\right)}\right]}^2& \left[\mathrm{Equation}1\right]\end{array}$
where X, Y and covariance represent the following: X: Proportion of the position of each point, where the elastic modulus was measured, from the interior of the tube Y: Elastic modulus ratio in each region Covariance: Average of the product of deviations of X and Y.
