目前，大幅减少化石燃料使用被视为实现碳中和目标的主要举措。然而，目前的能源政策不可能在不牺牲经济发展和人民生活的情况下实现气候目标，因为化石燃料目前是主要能源。三维打印作为一种环境友好的制造技术，正在蓬勃发展，并被认为有利于能源结构调整和产业升级。尽管如此，其为全球碳中和做出贡献的潜力并未引起足够的重视。在此，我们探讨了3DP的应用及其在关键行业和应用中促进碳中和的潜力，包括制造业，建筑能源，畜牧业和碳捕获和储存（CCS）技术。3DP的增材制造和分散制造特性允许通过优化和轻量化设计，减少材料和能源消耗以及缩短运输流程来减少制造和建筑部门的温室气体（GHG）排放。此外，3DP能够精确制造定制的复杂结构和扩展功能材料，这使得3DP成为开发新型能源相关设备、养殖肉类生产技术和CCS技术的创新替代方案。尽管如此，3DP的大多数应用仍处于早期阶段，需要进一步探索。我们呼吁进一步研究，以准确评估3DP的温室气体减排潜力，并使其更好地参与和部署，以更好地实现碳中和。
At present, dramatically reduction of fossil fuel usage is regarded as a major initiative to achieve the carbon neutrality goal. Nevertheless, current energy policies are unlikely to achieve the climate goal without sacrificing economic development and people's livelihood because fossil fuels are currently the dominant energy source. As an environment-friendly manufacturing technology, three-dimensional printing (3DP) is flourishing and is considered beneficial to energy structure adjustment and industrial upgrading. Despite this, its potential to contribute to global carbon neutrality has not attracted enough attention. Herein, we explore the application of 3DP and its potential facilitating carbon neutrality from crucial sectors and applications including manufacturing, construction energy, livestock, and carbon capture and storage (CCS) technologies. The additive manufacturing and decentralized manufacturing characteristics of 3DP allow reducing greenhouse gas (GHG) emissions in manufacturing and construction sectors by optimized and lightweight designs, reduced material and energy consumption, and shortened transport processes. In addition, 3DP enables the precise manufacturing of customized complex structures and the expansion of functional materials, which makes 3DP an innovative alternative to the development of novel energy-related devices, cultured meat production technology, and CCS technologies. Despite this, the majority of applications of 3DP are still in an early stage and need further exploration. We call for further research to precisely evaluate the GHG emission reduction potential of 3DP and to make it better involved and deployed to better achieve carbon neutrality.
