“…Instead, a common approach when creating models is to first create a monochrome base that has the correct size and shape, which is then hand‐painted. This approach has been used in a wide range of taxa, including invertebrates (Cianca et al, 2013), fish (Ziegelbecker et al, 2020), frogs (Gardner et al, 2021), lizards (Senior et al, 2021), birds (Biagolini‐Jr & Perrella, 2020), and eggs (Hauber, 2020; Igic et al, 2015). However, painting by hand reduces reproducibility, as it introduces individual variation to each model, creating less standardized stimuli.…”

Artificial animal models (often called "dummies" or "decoys") are widely used in field and laboratory studies as a substitute for live animals or taxidermic mounts. This practice has been employed for at least 70 years (Tinbergen & Perdeck, 1951), but in the last two decades has begun to incorporate 3D-printing to generate models. Models are advantageous as they have fewer ethical concerns than live animals, and mitigate any risk of damage to taxidermy specimens that would otherwise be deployed in experiments. Broadly, 3D-printing creates custom models through computer-controlled layering of material, based on digital designs (Gross et al., 2014). Other reviews have already addressed the developing role of 3D printing in the ecological sciences (Behm et al., 2018;Walker & Humphries, 2019), but to date, there are few recommendations for a simple, repeatable process that can generate shape and color-accurate models. We seek to rectify this, so that researchers using artificial stimuli can create highly detailed models in an easy and replicable manner.
