NAMIC invited World-Class Speakers to share their knowledges and experiences on Generative Designs, Simulation, Modelling and Industrial Applications of Digital Design Solutions.

“Generative Designs, Simulation and Modelling” Session:

Kick start with Mr John E. Barnes, Founder & Managing Director from The Barnes Group Advisors, shared the transformative role of design in driving innovation in the future of manufacturing. “Additive Manufacturing can be disruptive because it means that a lot of people need to learn new things.” said John. He also shared projects and case studies on how generative design and topology enhance additive manufacturing. To adopt AM, we need to reach out to existing engineers and teaching new engineers to have innovation led thinking and manufacturing thinking.

Coming on stage next is Mr Lin Kayser Sebastian, Co-Founder and CEO from Hyperganic Technologies AG. He shared examples of nature inspired design solutions for industrial application. Some product designs cannot be created using the computer-aided design as the technologies and requirement are getting more advance; we need to create the product using codes such as chips, we generate the chip based on our requirement. “Industry is changing dramatically. Today we have technology in our pockets which is also our incredible challenges. AM is the key element to embraces the industry.”

Simon Ng, Head of Design & Manufacturing Industry from Autodesk, introduced Autodesk Generative Design – it can generate multiple methods of Manufacturability (Additive, Subtractive and Formative). Users can input multiple materials and combinations of loads to generate the solutions. Showing example of the interior of a part with generative design, it reduces the weight of the part yet increase the performance of the part. The old way of designing – the designer/engineer uses computer as passive machine resulting in limited design options but the new way of designing with computer using artificial intelligence algorithms and designer/engineer unite as co-creators, we can create plenty of design options.

Andre Wegner, CEO from Authentise & Digital Manufacturing Chair at Singularity University, explained “Disappearing CAD doesn’t mean disappearing. Disappearing means shortening.” It is not about creating new design, it is about new production design such as orientation, support and nesting. With the design tools are moving into the workflow, we can avoid late decisions and also open room for flexibility which leads to increase productivity. In today’s market, there are plenty of design tools and it is not possible to buy or learn all software. We need tools that require no learning, zero cost switching or pay-per-use methods. The advantage of having more competition in the market leads to better products for users.

Dr Brent Stucker, Director from Additive Manufacturing ANSYS, shared the challenges in metal additive manufacturing. In the building layer-by-layer process, we cause stress internally on the printed part. Distortion and shrinkage lines occur during printing; with simulation, you can accurately predict these anomalies. User can change the build orientation and/or part design to eliminate these anomalies. With the help of additive simulation software, it enables accurate predictions on optimal geometry, best build orientation, part distortion & stress, support distribution effect, build failure, porosity, microstructure and many more.

Before ending the “Generative Designs, Simulation and Modeling” session, Professor Kristin Woods, Co-Director IDC SUTD, invited the panelists on stage at the Panel Discussion on the topic “The Impact of Design on Industry 4.0: A Designed and Systematic Approach To Industrial Solutions”.

“Industrial Applications of Digital Design Solutions” Session:

After the networking lunch, Mr Lior Polak, CEO & Co-Founder from Assembrix, sharing on stage the distributed manufacturing in action – the dynamic machine allocation and real-time monitoring. With the Virtual Manufacturing Space (VMS), you are able to print your file anywhere (internal or multiple suppliers); it doesn’t need to be near you. Using VMS, user is able to lock the part in a specific location in the printer and set the specific parameter for the part; this will control the IP of the part. The printer’s owner will not be allow to change the parameter.

Gregor Reischle, Head of Additive Manufacturing from TUV SUD, shared the impact of design optimization on additive manufacturing from the certification and testing perspective. Today AM industry is within its “early majority phase”, where it is unclear for many implementers where to focus on. Tomorrow our iAM readiness initiative will provide a holistic and focused commitment towards high-end manufacturing. Some of the pain are no reproducible production, personal skills are not well defined, standard landscape incomplete and insufficient reliability. On the other hand, the gain will be AM specifics-related Quality Mark for Machines, production sites, material and people.

What are the top 5 design tips for production-level printing? Yathiraj Kasal, AddWorks Leader Asia Pacific from GE Additive, shared the top 5 tips for design success with the audiences with illustration. First tip is numbers, numbers don’t lie. Business case critical first step for ensuring successful additive adoption for production. Compare and analysis the cost saving and performance factors between conventional fabrication and additive component. Second tip is back to basics, we must understand the part function, requirements, interfaces, materials and system level impacts. An example given was using additive manufacturing, the team redesign the part from an assembly of 20 components to 1 part without reducing the performance, and instead, it reduced 30% of the weight and 60% on the cost. The third tip is to fail fast – validate features, function, performance and iterate design early. The last 2 tips are optimize for productivity and be neighborly. Yathiraj also shared the case studies of their projects using intelligent design on additive manufacturing like the CFM LEAP fuel nozzle, GE9X LPT blade production and GE Aviation’s power door opening system bracket.

Coming on stage next is Dr Guglielmo Vastola, Scientist from A*STAR Institute of High Performance Computing, sharing the digitally correlating design, material and processes to unveil next-generation simulation software for additive manufacturing. Dr Guglielmo explained how they make use of simulation on the additive manufacturing process of a thin-wall square tube to improve and produce the consistent straight part. The simulation showed the distortion experienced by the part as it is being built, using the analysis, they modified the wall thickness and fillet radius as well as the parameter setting like the slicing in layers, material properties and the post-processing. It may be a simple geometry but it may not be a simple outcome. Using simulation, they are able to predict the distortion area that may cause inconsistent surface. The challenge for DfAM is not design on the shape only but the combination of geometry, powder and microstructure. Dr Guglielmo shared how they address DfAM through IHPC’s “Digital Twin” platform.

Herman von Bolhuis, CEO from 3D Makers Zone, introduced Amsterdam Smart City – the innovation platform that brings together proactive citizens, innovation companies, knowledge institutions and public authorities to shape the city of the future. 3D Makers Zone is one of the organizations under the Digital City category. Herman shared what should aspiring startups and tech entrepreneurs look out for in their 3D Printing business. We need to focus on solutions not technologies, start small and fail fast. Fail fast means faster turnaround for improvement before investing big.

Over the stretch of inspiration and engagement presentation from all the world-class speakers, the event moved on to the last section of the whole conference – the Panel Discussion on the topic “Global Perspectives: How will Design and AM Technology Transform the way We Live, Work and Play to create a World Class Livable and Loveable City?”

SUTD-Miniwiz Sustainability in AM Design Thinking Workshop

Javier Fernandez (left) and Stylianos Dritas (right), both are Assistant Professor from SUTD, shared with the audiences on Digital Biominetics – Sustainable Materials and Manufacturing. The molecular structure from the nature and the different type of materials. There are many materials around but it is not about the material, it is about how we use them. The structural method of how we print the material will enhance the strength and properties of the end product.

Javier and Stylianos also shared the anatomy of their problem encountered and the printing process of the tallest 3D Printed Biological Sculpture at SUTD lobby. There is a great reduction in weight for the sculpture during the wet state and the dry state from approx. 479.40kg to 95.88kg.  The sculpture was made from the natural mixture of Chitin, Cellulose, Vinegar and Water.

Ar. Tan Szue Hann M Arch, Managing Director from Miniwiz Singapore, introduced circular economy. The concept of recycling resources for regeneration in counter to the “take-make-dispose” consumerism culture. It is an economic system where products and services are traded in ‘cycles’ and the aim is to retain as value as possible of a product and part.

Hann also shared projects of buildings – Eco-Ark in Taipei, Jackie Chan University in TianJin, Jackie Chan Hotel in Beijing, Anything Butts in Rome, etc. Apart from projects from other countries, Temasek Shophouse is the project that we are working on with the interior made out of recycled materials.   Recycle resources can also applied to furniture, consumer products and apparel made from recycled resources. The jacket that Hann is wearing is also made from PET bottles.

To bring the process of recycling closer to the public, Miniwiz created Trashpresso, a portable trash recycling machine, that can be brought to anywhere in the world. Plastic waste goes into one end and building tiles emerge from the other end.

CADFEM ANSYS AM Simulation Workshop

Opening remarks by Professor Jerry Fuh, Centre Director of AM NUS, Proj Jerry Fuh strongly believe that additive manufacturing needs many parties (designers, researchers, companies, etc) to work together to bring AM to higher level. Although 3D Printing has becoming more mature but there is still room to enhance because the printed results are still not consistent.

Nico Nagi from CADFEM GmbH Germany, introduce additive manufacturing process simulation using ANSYS. Nico shared about the topology optimization, lattice structures, using AM to produce complex parts and how to reduce material costs. Nico also shared the STL preparation before Additive Manufacturing Process Simulation and the expectation vs reality during printing. What are the benefit to process simulation? With simulation, it avoids trial and error, estimate the deformation and stresses; allow you to change the process parameters and support structure before printing. With the live demonstration of ANASYS software, audiences had a better understanding and visualization of the application. Introducing the “Tetraeder mesh”, this is the best mesh for simulation.

Yan Wentao, Assistant Professor from NUS, shared about the case studies of their project using ANSYS simulation on computational modeling of thermal stress and distortion for additive manufacturing of new metallic materials. Professor Yan explained the influence of power, scan speed, scan pattern, placement and material. Using ANSYS simulation, they achieved uniform assumed strain model.

 

 

 

 

 

Altair/ATE Design Software Simulation Workshop

Mangesh Gite, Technical Manager from Altair and DfAm Consultant from Nanyang Polytechnic, empowered the knowledge to design for additive manufacturing utilizing topology optimization and lattice structures as well as the challenges faced. It is important to improve the product performance by utilizing the design freedom. Altair’s topology optimization allows user to define the design space, non-design space, boundary conditions, loads and material properties and it will advice the solution of the optimized design. Optimization is not a one click solution. Mangesh shared the process of topology optimization and case studies of different projects.

Dr. Stephan Daynes, Scientist II from Singapore Institute of Manufacturing Technology (SIMTech), shared the lattice (cellular) structure in nature such as human femur with load path alignment, sea sponge using hierarchical design for ductility and buckling resistance, honeycomb with efficient packing, dragon fly wing using stochastic pattern, human skull with impact protection as well as tree growth around the branch that enable efficient load transfer. Dr. Stephan shared the different type of lattices (strut-based and surface-based). Using additively manufactured lattice structures allow impact absorption, stiffness and strength, thermal management and many more.

Dr Stephan also shared their case study during their current research at SIMTech on Topology Optimisation and Functional Grading showing that significant stiffness and strength improvements may be achieved through non-uniform unit cells and functionally-graded designs.

Materialise Process Optimisation Workshop

Suresh Ratnam, Design Engineer from Materialise, introduced Materialise Magics software – 3D Print Suite for Data and Build Preparation to the audiences. Additive Manufacturing had been widely used at various industries such as Aerospace, Automotive, Prototyping, Sports, Fashion, Healthcare, Eyewear and Consumer Goods.

With examples, Suresh shared the 6 Drivers for 3D Printing: Design, Time-to-market, Cost saving, Customization, High complexity and Small series. During design, we need to have design freedom for functionality like lightweight structures, when you have limited space or when you need to transport air, water or heat. One of the case study on Smoby Mold, they used AM to create the conformal cooling and lattice structure within the core insert, resulting in better cooling.

During the hands-on workshop, Suresh shared how to do basic fixing of errors such as inverted normal, bad edges, holes and shells. Audiences each given a 2 weeks trial license to try on their own laptop and experience themselves.

At the second half of the workshop, Suresh shared the Design & Engineering case studies from Philips, Volvo, Mammoth and Grippers.

Autodesk Generative Design Workshop and R&D Centre Tour

Sharing with the audience “The Future of Making with Autodesk Generative Design”, Mr Chui Thiam Yaw, Senior Solutions Specialist, explained the benefit of generative design technology. A design exploration and manufacturing solutions technology that enables multiple CAD-ready solutions with real-world manufacturing constraints and performance requirements.

Generative design has been used on industrial machines, heavy equipment and high tech devices. Company, Edera used generative design on their rotational spine protection (RSP) system to increase strength and limit rotation to prevent spinal fractures during sport activities. General Motors used generative design to consolidate 8 components into 1 part with 40% lighter yet 20% stronger. Besides Edera and General Motors, Mr Chui also shared case studies from NASA Jet Propulsion Laboratory’s lander, Whill’s Mobility wheelchair and Claudius Peters’ industrial equipment.

Divy Kishor Tiwary, Additive Manufacturing Specialist – APAC from Autodesk, shared the product development process using topology optimization between traditional design method and generative design method. With the help of Fusion 360, you can generate multiple validate manufacturing options of the generative design at the iteration phase and select the best design for production; reduce the time to market and increase productivity.

Divy also shared the benefit of simulation; without simulation, designer can only make changes to the product after receiving the final part but with the help of simulation, designer can make improvement on the product such as adjust the parameters or compensate geometries on the product on warpage reduction before fabricating the final part. This will reduce the time spent and save cost.
