Fine Metal Powders

Metal additive manufacturing utilizes fine metal powders to construct robust, intricate components through computer-aided design (CAD) programs or 3D scanning, say sources from IIT Mandi.

This layer-by-layer manufacturing process offers flexibility in designing complex structures, finding applications in diverse industries such as aerospace, automotive, spare parts, heat sinks, biomedical devices, and construction materials, say sources from IIT Mandi.

They have meticulously detailed the extrusion-based process, termed mFFF/FDMet (metal fused filament fabrication/fused deposition of metals), in their publication in the journal Composites Part B.

Real-life application

Explaining the real-life application of the research, Mr. Naveen Kumar Bankapalli, Research Scholar, IIT Mandi, said, “This analysis empowers individuals, industries, or researchers to independently develop and implement this technology, facilitating cost-effective mass production of metal parts.

Particularly noteworthy for aerospace applications due to its lightweight nature, the extrusion-based process outshines current metal additive manufacturing alternatives, said Naveen Kumar of IIT Mandi.

Popular

While Powder Bed Fusion (PBF) and Direct Energy Deposition (DED) are popular metal additive manufacturing technologies, the extrusion-based method distinguishes itself by being more cost-effective, less hazardous, and offering greater design freedom, say sources from IIT Mandi.

Employing unique filaments composed of polymeric additives and metal powder, the mFFF/FDMet technique allows for versatile shaping and avoids the hazards associated with fine metal powders in PBF and DED processes, say sources from IIT Mandi.

Despite its lengthier process, it proves more economical for mass production of metal parts, in comparison to the conventional methods.

This underscores the need for an accessible additive manufacturing system capable of producing metal samples quickly, inexpensively, and creatively, say sources from IIT Mandi.

Importance

While stressing the importance of adopting this novel technology, Dr. Prateek Saxena, Assistant Professor, School of Mechanical & Materials Engineering, IIT Mandi, said, currently, only foreign companies dominate this entire process, creating a monopoly.

Our aim is to empower potential producers with a thorough understanding of the process, enabling independent development of the technology, said Dr Prateek Saxena.

Momentum

The global metal 3D printing industry is gaining momentum, evident in initiatives like the US Air Force’s second AM lab for aircraft parts and Indian steel giants entering the fray.

Recognizing the potential of additive manufacturing, the Indian government is committed to developing indigenous products for various sectors.

The schedule to submit applications for JEE Advanced 2025 has been announced along with that of AAT 2025 registration,

Application process for AAT starts after result declaration of JEE Advanced. This year too, the trend is no different.

Who will conduct AAT 2025?

AAT 2025 will be conducted by IIT Kanpur and is expected to see a participation in impressive numbers. The same institution is conducting JEE Advanced 2025.

Details about the exam are available on the official website mentioned above. Students who pass AAT 2025 will be able to study BArch in IIT Roorkee, IIT Kharagpur and IIT (BHU) Varnasi.

Who can take up AAT 2025 registration?

Students who have passed JEE Advanced 2025 with required qualifying marks can take up AAT 2025 registration. Applying for JEE Advanced requires a pass in JEE Mains.

Candidates who have passed plus two with maths, physics and chemistry as subjects will be able to take up JEE Mains registration. The process to take up JEE Advanced AAT 2025 registration is online.

1. The URL has to be typed into the browser and the webpage has to be allowed to download.

2. Once the website is available, students should click the link for JEE Advanced AAT 2025 registration and enter JEE Advanced 2025 registration number, their date of birth, mobile number and email address.

3. Post providing the above details, applicants will be asked if they are interested in AAT. Students have to answer ‘Yes’ to take up JEE Advanced AAT 2025 registration.

4. Candidates have to provide the required information and choose the centers where they wish to write the exam and submit the form.

5. They will receive message indicating successful completion of JEE Advanced AAT 2025 registration.

The message has to be downloaded and a printout of it has to be taken and preserved for use in future. This could be of use during the admission process.

Website for JEE Advanced 2025/AAT 2025 Registration is Here

Exam pattern

Candidates who have completed JEE Advanced AAT 2025 registration must also know the exam pattern if they are to score good marks.

Those who have taken up AAT 2025 registration can take up the exam which will be held in offline mode, as a pen and paper mode test.

Candidates will have three hours time to answer all the questions. The medium of the test is English.

The sections in the question paper are – Imagination and aesthetic sensitivity, three dimensional perception, Geometrical drawing, Freehand drawing and Architectural Awareness.

Syllabus for AAT 2025

The next thing to do after completing AAT 2025 registration is focus on preparing for the test.

The subjects to be studied while preparing for AAT 2025 are mentioned below. Candidates can also refer the official website for more information on syllabus when the registration for the exam begins:

Geometrical Drawing

Exercises in geometrical drawing containing lines, angles, triangles, quadrilaterals, polygons, circles, etc. Study of plan (top view), elevation (front or side views) of simple solid objects like prisms, cones, cylinders, cubes, splayed surface holders, etc.

Freehand Drawing

This would comprise of simple drawing depicting the total object in its right form and proportion, surface texture, relative location and details of its component parts in appropriate scale.

Common domestic or day-to-day life usable objects like furniture, equipment, etc., from memory.

Three dimension perception

Understanding and appreciation of three-dimensional forms with building elements, colour, volume and orientation. Visualization through structuring objects in memory.

Architectural Awareness

General interest and awareness of famous architectural creations – both national and international, places and personalities (architects, designers, etc.) in the related domain.

Imagination and Aesthetic Sensitivity

Composition exercise with given elements. Context mapping.

Creativity check through innovative uncommon test with familiar objects. Sense of colour grouping or application.

The medium of the test is English. The sections in the question paper are – Imagination and aesthetic sensitivity, three dimensional perception, Geometrical drawing, Freehand drawing and Architectural Awareness.

The admit cards obtained for JEE Advanced 2025 can also be used to gain entry into the test centers for AAT 2024.

Point to remember

Candidates can visit the official website of JEE Advanced exam for more information on JEE Advanced AAT 2025 registration and other related topics.

The students have to quickly take up the AAT 2025 registration as the time left would be very short.

Like JEE Advanced exam where the registration is open for a longer duration, that of AAT 2025 registration is open for only a short period.
