Artec 3D launches metrology kit for more accurate 3D scanning

Artec 3D has announced the release of his news Metrology kit, allowing for deformation analysis and greater accuracy in measuring objects and areas of all sizes. The 3D Optical Coordinate Measurement System is available in Entry and Professional versions and offers a versatile, easy-to-use photogrammetry solution for high-accuracy inspection in the Aerospace & Defense, Automotive and Industrial industries. oil and gas. The kit is compatible with inspection software solutions such as PolyWorks and Geomagic Control X, and includes the Metrology Kit plugin, scale bars, adapters, measurement targets and a camera with a resolution of up to 30 .3 megapixels and a 28mm wide-angle lens.

DaaKS and VDI certified, the Artec Metrology Kit is fully portable, so it can work as a standalone optical measurement solution, as well as a benchmarking tool for better remote 3D scanning performance. It offers accurate measurements in less than 15 minutes, can capture moving objects and provides point accuracy (RMS) up to 0.002mm + 0.005mm/m and length measurement accuracy up to 0.015mm + 0.015mm /m.

VoxelDance Releases Latest Version of All-in-One AM Build Prep Software

This month, software provider AM VoxelDance published Additive Voxeldance 4.0, which is the latest version of its all-in-one AM build preparation software. This release, with over 30 new features and optimizations, will allow users to increase industrial 3D printing productivity. Some highlights of the VDA 4.0 release are a new shrink wrap feature, which can accurately calculate and wrap a layer around the part while ignoring internal details; edge reinforcement for stronger support retention; web support and tree support; a smooth mesh feature that removes sharp details to ensure more attractive geometry, and more.

After listening to customer needs from over 9 verticals including aerospace, medical, automotive, molds, footwear, dental, education, jewelry, prototypes, and more, we have introduced new more interesting features and further optimized the algorithm. VDA 4.0 fully supports SLM, SLA, SLS printing technologies and is a milestone for industrial applications,” said Chaoxin Zhang, CEO of VoxelDance.

Chromatic develops Smooth-Mode technology for rubber parts

Chromatic’s RX-AM™ materials and technology platform are featured here for 3D printing smooth polyurethane eyelets with Smooth-Mode.

3D printing technology provider Chromatic 3D materials recently presented its new Smooth Mode technology to 3D print durable rubber parts with ultra-smooth surfaces at commercial volumes. The company’s team of AM experts have refined the viscosity and surface tension of Chromatic’s 3D printable thermoset polyurethane materials, and Smooth-Mode actually uses chemistry to create smooth, ultra-bonded parts. Industrial manufacturers can now use smooth mode with Chromatic’s RX-AM materials to print smooth, high-quality polyurethane parts, such as seals, gaskets, and grommets, that have superior aesthetics, more dimensional accuracy, and more. fine and no post-processing or surface finishing needed. .

“Sealing requires a smooth surface, but 3D printed parts have always had layer lines or roughness,” explained Dr. Cora Leibig, the founder and CEO of Chromatic 3D Materials. “We have developed a way to easily and cost-effectively print ultra-smooth 3D products without additional steps. This is a breakthrough for 3D printing those professional applications that need to be airtight and waterproof.

CSEM 3D printing tubes with integrated sensors

CSEM’s AHEAD project is developing additively manufactured pipes with integrated sensors.

Swiss Center for Electronics and Microtechnology (CSEM) coordinates the EU-funded AHEAD (Advanced Heat Exchange Devices) project, which aims to improve the performance of thermal control systems by 3D printing tubes with integrated sensors. These systems are critical components in many high-performance devices, such as space rockets and satellites, but most of today’s thermal control systems are bulky and require many connecting cables. The goal of the AHEAD project, which is expected to last two years, is to use AM to develop wireless, compact and less expensive systems to improve efficiency and enable real-time data collection. AHEAD consortium partners are currently targeting space modules and new particle detectors from the European Organization for Nuclear Research (CERN) as applications, although they hope to bring the technology to the pre-industrial stage so that it can be used for a variety of applications, including machine tools, irrigation mechanisms, heating systems and industrial cooling, automotive parts, etc.

“Generally speaking, we aim to develop technological building blocks that can be used to integrate electronic components such as cables, connectors and sensors into many types of 3D printed objects. The ability to integrate sensors into process equipment will be an important feature of Industry 4.0. The data collected by these sensors can be used to feed artificial intelligence algorithms for process control, process optimization and predictive maintenance,” said Hervé Saudan, project coordinator at CSEM.

UK researchers are developing a swarm of drones for aerial 3D printing

Finally, a research team from imperial college londonthe University of Bathand University College of London was inspired by the swarms of bees who designed their hives to create a fleet of drones able to 3D print structures autonomously while flying through the air. The drones act autonomously, but work as a team, and the researchers hope the platform, dubbed Aerial-AM, can one day be used to quickly build bridges, shelters, and even houses, in hard-to-reach areas. to help with weather emergencies like wildfires and hurricanes. In several proof-of-concept tests, which are described in a research paperthe self-organizing drone swarm was able to print structures with minimal human supervision using materials like foam and a cement mix.

The team developed a software framework for their swarm that was able to tap into natural precedents and previous engineering ideas to operate each drone in tandem with the others while extruding material, but not flying into each other. . Aerial-AM combines AI and physics to create two types of flying robot platforms: the BuildDrone, which autonomously deposits materials according to its program, and the ScanDrone, which uses computer vision to scan construction in progress for quality control purposes, then provides feedback with each deposited layer. The only part that human supervisors are part of is running a pre-print simulation to generate virtual work using three or more drones to determine the best way to print a material.
