These are physical objects designed for amusement and play, created using additive manufacturing techniques. Digital models are converted into three-dimensional forms by successively layering materials such as plastics, resins, or even metals. A common example involves downloading a file from an online repository and using a desktop machine to produce a miniature car.
The appeal of these items lies in their customizability and accessibility. They offer opportunities for personalized designs, rapid prototyping, and on-demand production, potentially reducing reliance on traditional manufacturing processes and supply chains. Historically, this method offered niche applications, but advancements in technology and materials have expanded its potential for both individual hobbyists and commercial enterprises.
The following sections will delve into the design considerations, material choices, printing processes, and safety aspects related to constructing objects of this nature, alongside exploring the potential impacts on the traditional manufacturing of playthings and the future trends in this rapidly evolving field.
