“…Heat from a laser can also be modulated to a much higher degree than other heating appliances by adjusting the power, speed, wavelength, and beam intensity. Being that lasers are a fairly new application in the food domain 8 , more formal regulations would need to be implemented for more widespread use.…”

To date, analog methods of cooking such as by grills, cooktops, stoves and microwaves have remained the world’s predominant cooking modalities. With the continual evolution of digital technologies, however, laser cooking and 3D food printing may present nutritious, convenient and cost-effective cooking opportunities. Food printing is an application of additive manufacturing that utilizes user-generated models to construct 3D shapes from edible food inks and laser cooking uses high-energy targeted light for high-resolution tailored heating. Using software to combine and cook ingredients allows a chef to more easily control the nutrient content of a meal, which could lead to healthier and more customized meals. With more emphasis on food safety following COVID-19, food prepared with less human handling may lower the risk of foodborne illness and disease transmission. Digital cooking technologies allow an end consumer to take more control of the macro and micro nutrients that they consume on a per meal basis and due to the rapid growth and potential benefits of 3D technology advancements, a 3D printer may become a staple home and industrial cooking device.

“…After the scolding and sintering of a layer, the powder sinks to a layer and a new layer of powder is spread. Layer‐by‐layer cumulative sintering rapidly produces products with complex shapes, and moulding is completed at the end of printing without post‐curing (Teng et al ., 2021a). Selective laser sintering/hot air sintering printing has great developmental potential in the food production and medical fields in the future.…”

“…Although selective laser sintering/hot air sintering printing is able to print the ready‐to‐eat food with higher spatial resolution in designing products, the laser sintering laser particles used in this type of 3D food printing technology may alter the substances in the food, which may result in unpredictable food safety issues, consequently causing potential risks for the nutrition and health of astronauts. Moreover, the laser used in selective laser sintering/hot air sintering printing usually has high energy (Teng et al ., 2021a). This could be a potential threat to the safety of manned spacecraft and experimental equipment.…”

Three-dimensional (3D) food printing is a digital food engineering method that has a remarkable application potential in long-term manned spaceflight. Extrusion-based 3D food printing, among the available 3D food printing techniques utilised in the food industry, is one of the most suitable printing methods for manned spaceflight. Extrusion-based 3D food printing could suffice most of the energy and personalised nutritional requirements of astronauts during long-term stay in space by utilising fruits, vegetables, meat products, and nutrients as printing materials. However, 3D food printing in manned spaceflight is still limited by technologies and costs such as printing materials, microgravity, post-processability of food, and engineering transportation under the existing technical conditions. Therefore, this article reviews the 3D food printing and manned spaceflight technologies that are currently available and discusses the challenges involved in 3D food printing in manned spaceflight, thus providing a theoretical basis for future 3D food printing for space missions.

“…Hence, the interaction of femtosecond laser pulses with different materials has attracted significant attention in view of its characteristic features of low heat-affected zones, minimal collateral damage, and precise micromachining [18][19][20]. Since its discovery, the laser ablation process has been explored in many fields pioneering nanomaterials for applied sciences [21][22][23][24][25][26]. The wide range of practical applications for femtosecond lasers includes micro-materials processing [27], surface nanotexturing [28], ophthalmology [29,30], dental surgery [31] and so on.…”

We report a study of the role of material’s conductivity in determining the morphology of nanoparticles and nanostructures produced by ultrafast laser ablation of solids. Nanoparticles and textured surfaces formed by laser ablation display a wide variation in size and morphology depending on the material. In general, these qualities can be grouped as to material type, insulator, semiconductor, or metal; although each has many other different material properties that make it difficult to identify the critical material factor. In this report, we study these nanoparticle/ surface structural characteristics as a function of silicon (Si) resistivity, thus honing-in on this critical parameter and its effects. The results show variations in morphology, optical and non-linear properties of Si nanoparticles. The yield of colloidal Si nanoparticles increased with an increase in the conductivity of Si. Laser-induced periodic surface structures (LIPSS) formed on ablated substrates are also found to be sensitive to the initial conductivity of the material. Further, the laser ablation of Gamma-irradiated Si has been investigated to verify the influence of altered conductivity on the formation of Si nanoparticles. These observations are interpreted using the basic mechanisms of the laser ablation process in a liquid and its intricate relation with the initial density of states and thermal conductivities of the target material.
