Questions related to Additive Manufacturing
I have a gas atomised powder. I want to use it in laser powder bed fusion. I will use vibratory siever to sieve the powder. What sizes of sieves do I need?
Hello,
I have a problem in classification of "Additive Manufacturing" techniques. There are several classification for Additive Manufacturing e.g. Powder, Extrusion, Resin etc.
Actually, I am OK with them, but I cannot find 3D Bioprinting. Is 3D Bioprinting a classifies branch of AM?
My problem is exactly classification of them.
The AlSi7Mg sample was additive manufacturing by the PBF method and heat treated 480℃-6h and 550℃-6h.
When the residual stress of the top view and the side view(Figure) was measured by XRD, the following results were obtained.
As-built
Top : 47.4 MPa
Side : 134.9 MPa
480℃-6h
Top : -33.7 MPa
Side : 2.1 MPa
550℃-6h.
Top : -38.8 MPa
Side : -36.1 MPa
So, I have some questions about the results.
1. In case as-built sample, why is there such a big difference between Top and Side?
2. In case 480℃-6h heat treatment, after heat treatment, the Top changed greatly from tension to compression stress, but why didn't the Side change like this?
3. After heat treatment, Why tensile stress change to compressive stress?

Dear Professors/Researchers,
Can you please suggest, the latest Additive Manufacturing & Casting Techniques used for Aerospace Applications?
Hello everyone,
there seems to be a lack of resources, even though SLA additive manufacturing is widely used. Would anyone be so kind as to point me towards a source determining the Poisson's ratio of standard photopolymers in cured state? I'd be especially interested in Formlabs Clear resin and Formlabs Tough 2000. Their documentation does not provide a number, unfortunately, and literature results for other resins are surprisingly scarce as well.
Thank you all in advance.

The conference should meet the following criteria: Organized by reputable professional societies or bodies including ASME, SPIE, ISME, ISTAM, IMechE, IFToMM, IEEE, APS, ACM, ACS, IOP, Elsevier, Springer, IIAV, AMSI, CSIR laboratories, design society, CIRP, CADA, Japan Society of Kansei Engineering, International Association of Packaging Research Institute, Indian Society of Ergonomics, Usability Matters ORG (UMO), International Ergonomics Association, International Institute of Information Design, Vienna, and listed among the first 500 conferences in the Microsoft Conference Ranking.
Global market size of additive manufacturing(AM) is still very low. AM is seen as a way to confront challenges by significantly reducing time-to-market and opening up new opportunities for the economy and society. There is still something preventing manufacturers (may be challenges like technical, financial, capability, design, IT integration etc.), from integrating AM technologies more generally into manufacturing process. Many analyses are limited when it comes to quantifying the environmental impact. Economical products are more attractive and demand and sales might be good though, but major difficulties is to factor impacts into business calculation?
Ideas from artists flow through their hands to create art.
Ideas from designers not able to build from a sketch are drawn on paper or CAD programs and sent out to manufacturers or makers.
CAD design files have different views or perspectives. 3D CAD designs could be visualized in horizontal cross-sections to see internal features. Layered slices of CAD designs gave way to making models of 2D layer views and then 3D Models.
Makers wanted to imitate materials to make models more realistic. New machines had to be designed to automatically dispense existing materials for 3D models.
These 3D machine processes were labeled Additive Manufacturing Processes.
Some hand-held machine tools already existed for adding materials. (1) Hot-melt glue guns,
(2) inkjets or paint sprayers, (4)clothing and sheet laminators, (5) welding tools, etc.)
AM Processes chose materials based on tools for building 2D layers. The basic AM processes are computer automated (1) contact deposition with melted materials, (2)inkjet non-contact deposition with liquid materials, (3) Powder Bed, (4) Sheet lamination, (5)Welding or wire feed deposition and (6) Bath photopolymerization.
Patents have appeared with combinations of these processes. Powder "Binder Jetting", Laser Powder welding, Electron Beam powder welding, Liquid metal Jetting, Powder sintering in ovens, and others.
This discussion is about the basic AM Process of producing a solid single 3D layer vs producing a full finished 3D Model with "one" process. All of the above processes result in a solid 3D layer completion with one defined operation except Powder "Binder Jetting". The binder fluid is only water and a finished solid layer does not exist until the finished Binder Powder model is put into an oven and sintered. Binder Jetting is not a trademark but it is an AM Process and I believe it is identified incorrectly. It may never get changed but I need some input about this AM Process name.
3D Printing means producing a 3D object or any portion of the object as the process is performed. A partial layer is still a 3D model.
Think about it. Can I deposit "unsolidified" materials in small layered steps into a tray and put it into an oven, bake it, to be a finished pie and call it a 3D Printed Model?
Has anyone gone through the Wohler's report_2023 yet? Its pros and cons? What are the ways to obtain its e-copy? Its subscription is very costly for a normal researcher (around 750 USD per user). Any alternatives to get similar kind of data as that of the report?
Dear ResearchGate community,
I am currently exploring 3D printing of telecommunication antennas for deployment in rural areas of Nigeria. The 3D printer available to me utilizes PLA, which is susceptible to melting under prolonged sun exposure. I am seeking advice on suitable coatings to protect the antennas from sunlight.
Additionally, I would greatly appreciate recommendations for research papers that address similar challenges or provide insights into protective coatings for outdoor 3D printed structures as it'll be of immense help.
Thank you for your expertise and assistance.

Hello good people
I am simulating multipass multilayer additive manufacturing with ANSYS transient-thermal module. The problem is that the Gaussian heat source (APDL code) works fine with the first layer, but when it comes to the second layer, it does not work. The heat flux does not even initiate for the second layer. I tried generating the code with a different coordinate system for the second layer, but that didn’t work either. I also tried incorporating the ‘z’ or the height of the second layer in the equation. Unfortunately, it didn’t work. But when I put the heat sources for both layers in the same time step, it works for both layers; they don’t work in different time steps.
How can I modify my code so that it works for the SECOND LAYER in the SECOND TIME STEP or any layer after the first layer?
The APDL code is mentioned below-

Hello,
I am doing an additive manufacturing simulation in ABAQUS/CAE 2017.
I have two working subroutines: DFLUX and UEPACTIVATIONVOL which both do their jobs correctly in separate models. I need to combine them but for my moving surface flux, the surface I define in the model does not work due to the activating elements during the analysis form the UEPACTIVATIONVOL. (The surface I define in the GUI for the heat flux does not exist at t = 0 since the elements are inactive)
Is there a way to define the top element face as a surface and change that in a subroutine for my DFLUX subroutine to call so the heat source will be applied on the surface of elements on one layer and then apply to the elements top face on the next layer?
Thanks in advance for your help!

What are advantages of smart factories?
I've recently published the following article in the Korea Times.
And how do you feel about smart factories? Please be as specific as possible when expressing your comments.
What are advantages of smart factories?
Humanity has come a long way from its earliest traces of civilization. Through industrialization, advancement has been brought to the world like never before. The introduction of human labor and later on machines were heightened to a great emphasis, being the main fuel of the economy. Manufacturing became a core concept in terms of civilization during the height of capitalism; a necessity in providing for the needs of citizens in terms of products, services and jobs among others.
It is probably right to say that humanity's current habits revolve around the whims and ways of capitalism. Despite the fact that humanity has highly benefited from different stages of industrialization, it has also revealed how it can be perilous and detrimental to citizens throughout the years in different aspects.
One of the dangers that capitalism and intensive labor pose toward workers would be the tendency of burnout from excessive and inhumane workloads. Burnout can also come from repetitive tasks, whereas humans are naturally inclined to look for new things to explore and experience from time to time.
More so, labor workers also frequently encounter the risks of unjust labor treatment, particularly in relation to wages, benefits and regulations. Amid the introduction of artificial intelligence (AI) technology during the current Industrial Revolution (IR), the same issues regarding the negative sides of labor and capitalism maintain their prevalence. This is where the idea of smart factories enters.
In the simplest sense, a smart factory is a manufacturing site wherein the traditional workload is combined with smart machinery powered by huge data and technological systems. Smart factories are factories that are highly improved, innovated, and advanced, branching out as a contribution of IR 4.0. One of the great benefits that smart factories introduce would be the ability to shorten the duration and costs of operations in manufacturing.
This is because it is highly flexible in adapting with the usual processes that happen in the factory through the means of storage and analysis of huge data. In doing so, the manufacturing processes became more efficient and effective, lessening the workload that employees are usually tasked with.
A smart factory provides for the reduction of manufacturing process times and costs by adapting and optimizing operations as well as storing and analyzing vast amounts of data in real time. This leads to a more flexible, efficient, and autonomous production by encouraging workers to focus on improving processes rather than on mundane jobs, resulting in high value.
Smart factories gradually gear up society for IR 5.0, with the goal of creating a people-centered economy rather than a task-centric economy. As smart factories aim to lessen the workloads of human workers, it allows them to have more time for other fundamental things that comprise their lives, other than their jobs and careers. Smart factories give hope for individuals to have more time for recreation and leisure, as well as time spent with family, friends, and meeting new individuals instead of working for eight hours straight.
A smart factory strategy does not equate to a total replacement and retrenchment of employees with machines. Rather, it would employ the fusion of the work and effort of both humans and smart technology-powered machines. It adapts a system that is highly-digitalized wherein real-time data is optimized. Smart machines or smart robots can be programmed with repetitive and routine tasks that are usually compiled by the human workforce. Simply put, it brings forth a workplace and lifestyle for individuals that is both sustainable and humane.
It is well known that the height of capitalism involves intense competition within and outside of firms and companies. With that being said, the utilization of smart factories and artificial intelligence allows the opportunity for robots to be those involved in the competitions instead of relying on humans. This can be done in the way that smart robots will be mainly responsible for the heavy processes done during production. Thus, they will be liable for the quality of the manufactured goods which are the foundation of a company's competency compared to other companies.
In turn, this would relieve the human workforce from the added pressure that is embedded in the production process for the obvious reasons that they are held responsible for the product quality and output. Through smart robots, quality products and their output can be made, which will be the basis for the reputation of the company's name.
External influences such as the macroeconomy and the pressure it places on a firm and its employees can play a significant role in fostering a toxic workplace. Smart factories give us a chance to save humanity and society by providing a realistic, attainable and considerate alternative for the people.
Such an approach would provide the steps for a healthier and more sustainable lifestyle for humans in terms of realigning their relationship with work. Lastly, it promotes a society that looks out for the well-being of its citizens, instead of looking at them as mere workers.

I am interested in removing defects during metal LPBF like orientation adjustment, residual stresses, cracks, part failure, etc.
As we all know the best particle size for SLM is around 40um.
I was looking for a lab scale machine to produce my needed metal powders and I found ATO Lab Atomizer machine, although the company claims that the output powder of the machine is suitable for SLM but in its catalogue it is mentioned that the particle sizes are between 20 and 120um.
I am curious to know can I use that powder for SLM AD?
and also how many percent of that powder is under 50um?!

I'm starting a Thesis on the topic of Additive Manufacturing with the combination of flexible manufacturing/process build control. Can anyone suggest any research topic I can work on? Any reference paper or Thesis would be appreciated. Also, can you suggest which software I'll have to use in this research topic? Ansys?
My intention is to be able to see by LOM, the melt pools produced by the additive manufacturing process, and also the grain formation.
Any help or advice would be appreciated!
