Abstract
Three-dimensional
(3D) food printing is an emerging additive manufacturing technology that
enables the fabrication of edible products through the computer-controlled,
layer-by-layer deposition of food materials. Unlike conventional food
processing, 3D printing provides an opportunity to simultaneously control the
geometry, texture, composition and nutritional characteristics of food
products. The technology has attracted increasing attention because of its
potential for personalized nutrition, functional food development, alternative
protein utilization, food waste valorization and sustainable food
manufacturing. Extrusion-based printing remains the most widely investigated
approach because of its compatibility with a broad range of food materials,
relatively simple equipment requirements and ability to process viscous food
formulations. Other approaches include inkjet printing, binder jetting and
selective laser sintering. Successful printing depends strongly on the
rheological and physicochemical characteristics of the food ink, including
viscosity, yield stress, shear-thinning behaviour, cohesiveness and structural
recovery. Applications have expanded from confectionery and bakery products to meet
analogues, plant-based foods, dairy products, functional foods, nutritionally
fortified foods and foods designed for elderly and dysphagic populations.
Recent developments have also explored 4D printing, artificial
intelligence-assisted process optimization and the use of food-processing
by-products as printing materials. Despite these opportunities, challenges
related to printability, printing speed, food safety, nutritional stability,
consumer acceptance, standardization and industrial scalability remain. This
review summarizes the principles, printing technologies, food materials,
applications, advantages, limitations and future prospects of 3D food printing,
with particular emphasis on personalized nutrition and sustainable food
production.
