Many of us are familiar with the dreaded “spaghetti” effect when a print job goes wrong. Start-upGREENFILL3D，波兰3D印刷新闻提供商的纺纱公司CD3D现在，随着面食废物制成的新的可持续3D打印丝的发展，现在已经采用了这一点。
Named Branfill3D, the filament is made up of wheat bran, the waste left over from the production of pasta, PLA and several other biodegradable ingredients, and reportedly exhibits both resilient and flexible properties.
为了首次亮相，灯丝已用于3D印刷专有广告销售点（POS）摊位，该摊位将在相当合适的循环经济概念中容纳现成的意大利面。
Endless pasta-bilities
GREENFILL3D’s mission is to implement zero-waste ideas into the 3D printing sector in order to create new eco-friendly standards in the creation of everyday items. The start-up hopes to do this by processing eco-friendly thermoplastics that are combined with biodegradable or recycled ingredients and then using these materials to 3D print a range of products.
自去年7月以来，Greenfill3D一直与欧洲最大的食品生产商合作MASPEX Groupas part of the波兰企业发展机构s (PARP) ScaleUp Program. The joint project saw the company focus on wheat bran, a waste product left over from the pasta production process carried out by one of MASPEX’s main brands,Lubella.
The goal of the partnership was to produce a Point of Sale (POS) advertising stand made up of recycled waste of the same product it is presenting, in order to fit the ScaleUp program’s zero-waste and circular economy ideals.
MASPEX GREENFILL3D提供与waste raw wheat bran which the company then sieved and dried until it was suitable for combining with other biodegradable ingredients and PLA. The material was then processed into a thin filament wire, Branfill3D, that could be used as 3D printing feedstock.
然后，该材料被用于Greenfill3D的印刷农场的3D打印模块化POS架，该农场由40多台机器组成。据报道，使用Branfill3D打印的零件具有弹性，并且“在某种程度上”柔韧性，具体取决于特定组件的壁厚。根据GreenFill3D的说法，除了光滑的表面饰面外，小麦麸皮废物的纤维结构还为3D打印的零件提供了弹性。
Another rather niche observation by the firm was that the material gave off the scent of baked bread during the printing process, which apparently stays on the 3D printed parts for some time.
POS显示器由20％的Branfill3D细丝组成，而其架子连接器由PLA制成。总的来说，每个立场都包含34个要素，该元素是该公司声称的快速易于组装的要素。然后将支架安装在由100％可回收纸板制成的基座上，以使每个单元零浪费。
Dubbed “ecoPOS”, the 3D printed stands will be delivered to selected retail outlets “soon”, and will display Lubella’s ready-made pasta products.
While the POS stands are the first demonstration of GREENFILL3D’s new Branfill3D filament, the firm says it is currently conducting tests for an automotive customer and plans to successfully deploy the material to other industries, too.
3D printing with food waste
The circular economy is a concept that seeks to make optimum use of resources in order to avoid waste. Recent years have seen the各种与3D印刷相关计划的兴起aiming to develop closed-loop manufacturing processes to repurpose waste materials, particularly those from food-based sources.
One such initiative is theBARBARAproject, which at the end of 2020 concluded four years of research into从食物浪费中开发3D可打印材料和农业副产品。该项目为建筑和汽车领域生产了3D打印的原型，现在正专注于扩大其规模废物食物生物经济3D打印过程to a semi-industrial level.
Other recent examples of repurposing food waste for additive manufacturing processes include replacing petroleum-based PET with bioplasticsderived from coffee powder and orange peel并将食物浪费转换为可生物降解的PHA.
More recently, an alternative由康普茶茶垃圾制成的木材替代品was awarded last year’s national詹姆斯·戴森奖，现在正在寻求利用3D打印来扩展生产。
