This is the first draft of the large scale 3d printing protocol for granulated thermoplastics. The main purpose of this document is to share the key steps of operating, preparation, data entry, and optimization procedures while handling the robotic 3d printing equipment. One main aspect of this protocol is that it is independent of specific 3d printing hardware or software setups. The aim is to have the users from robotic 3d printing from various technologies follow these steps and be able to set the basics up when it comes to handling such 3d printers.

Bumping Elbows explores a workflow integrating 3D body scanning technology with robotic knitting to create personalized garments. Traditional 3D knitting development relies on 2D drafts and panels, rooted in industrial flatbed knitting practices. Our approach leverages accurate topology measurements from 3D body scans to directly inform garment design and production, allowing for custom fits to unique body shapes. We will demonstrate this process through live 3D scanning and software demonstrations, highlighting the challenges and opportunities integrating body scans and knitting techniques like goring. Our included software addresses limitations of previous work and outlines advancements needed for broader research adoption, emphasizing the potential of combining 3D scanning with robotic knitting. This method offers enhanced personalization and sustainability in garment production, showcasing the ongoing challenges and advancements in achieving precision in robotic knitting.

The short-term aim of this R&D project (financed by the Centre of Expertise Creative Industries) is to develop a virtually simulated textile database that renders 3D visual representations of these fabrics. The idea is for this database to be open source and be able to interface with 3D design applications such as those of Lectra. The textile database will include a number of different digital datasets per textile that contain information about the fabric’s drape, weight, flexibility etc., to virtually render prototypes in a 3D simulated environment. As such, in building garments via a 3D software design application, designers will be able to see how a garment changes as new textiles are applied, and how textiles behave when constructed as different garments. This will take place on 3D avatars, which may be bespoke body scans, and will allow for coordinated and precise fitting and grading.

From the article: Abstract Adjustment and testing of a combination of stochastic and nonstochastic observations is applied to the deformation analysis of a time series of 3D coordinates. Nonstochastic observations are constant values that are treated as if they were observations. They are used to formulate constraints on the unknown parameters of the adjustment problem. Thus they describe deformation patterns. If deformation is absent, the epochs of the time series are supposed to be related via affine, similarity or congruence transformations. S-basis invariant testing of deformation patterns is treated. The model is experimentally validated by showing the procedure for a point set of 3D coordinates, determined from total station measurements during five epochs. The modelling of two patterns, the movement of just one point in several epochs, and of several points, is shown. Full, rank deficient covariance matrices of the 3D coordinates, resulting from free network adjustments of the total station measurements of each epoch, are used in the analysis.

Enkele vooraanstaande instituten, zoals TNO1 en McKinsey2, geven aan dat 3D- printen de potentie heeft een nieuwe industriële revolutie tot stand te brengen. Dat 3D-printen ook binnen de podotherapie gebruikt gaat worden, is niet langer meer een vraag. Immers de eerste geprinte voetortheses (zolen) zijn inmiddels een feit. Interessant is de vraag hoe 3D-printen de podotherapiepraktijk zal beïnvloeden en wat de gevolgen daarvan zijn.

Dit onderzoek richt zich op het verkleinen van de kunstgrasberg. Gezamenlijk met ketenorganisatie GBN AGR en Joosten Group is een verkenning van 3D printen van Recycled Turf Agglomerate (RTA) uitgevoerd. Het materiaalonderzoek, verricht door Saxion Thermo Plastic composites Application Centre, aangevuld met datagegevens van GNB AGR en vergelijkingen met bestaand 3D printfilament leverde al inzichten op. Ook is een 3D printer gemodificeerd om gerecycled granulaat te 3D printen. Hierop zijn tests met verschillende recycled materiaal gedaan. Echter bleek het huidige RTA te vervuild om 3D prints te maken. Een alternatieve RTA, welke extra zuiveringsstappen is doorgaan, was goed 3D printbaar.

Many articles have been published on scale-down concepts as well as additive manufacturing techniques. However, information is scarce when miniaturization and 3D printing are applied in the fabrication of bioreactor systems. Therefore, garnering information for the interfaces between miniaturization and 3D printing becomes important and essential. The first goal is to examine the miniaturization aspects concerning bioreactor screening systems. The second goal is to review successful modalities of 3D printing and its applications in bioreactor manufacturing. This paper intends to provide information on anaerobic digestion process intensification by fusion of miniaturization technique and 3D printing technology. In particular, it gives a perspective on the challenges of 3D printing and the options of miniature bioreactor systems for process high-throughput screening.

Vertical urbanisation is perceived as necessary to accommodate a growing population but is associated with severe risks for human well-being. It requires a profound understanding of how archi-tectural designs can ensure visually readable and liveable environments before it has been built. How-ever, current digital representation techniques fail to address the diverse interests of non-experts. Emerging biometric technologies may deliver the missing user information to involve (future) inhabit-ants at different stages of the planning process. The study aims to gain insight into how non-experts (visually) experience 3D city visualizations of designed urban areas. In two laboratory studies, univer-sity students were randomly assigned to view a set of the same level of detail images from one of two planned urban area developments in the Netherlands. Using eye-tracking technology, the visual behav-iour metrics of fixation count and duration and general eye-movement patterns were recorded for each image, followed by a short survey. The results show how visual behaviour and perception are remark-ably similar across different detail levels, implying that 3D visualizations of planned urban develop-ments can be examined by non-experts much earlier in the design process than previously thought.

Anyone who has watched a child play with soft semi-liquid materials like honey, frosting, or slime, sees the fascinating interplay between design and physics. Many of us remember these experiences from our own childhood (or maybe not that long ago). These materials dribble and coil as they stack upon themselves when we drop them onto surfaces like cakes from small heights. This ludic behavior represents a physical phenomenon known as rope coiling. Recent research in 3D printing of clay and plastic has started to wonder how rope coiling can be leveraged to create new textures and textile-like structures through non-planar 3D Printing. These provide new tactile experiences in objects like cups and visual experiences in things like lamps. In this demonstrator, we invite researchers and practitioners to return to their childhood and dribble edible materials to understand how to advance additive manufacturing through interactive printing.
