ExOne Direct Material Printing - Binder Jetting TechnologyRicardo Toledo
Unique binder-based 3D printing technology was developed at MIT.
ExOne uses Binder Jetting technology to 3D print complex parts in industrial-grade materials. Binder Jetting is an additive manufacturing process in which a liquid binding agent is selectively deposited to join powder particles. Layers of material are then bonded to form an object. The printhead strategically drops binder into the powder. The job box lowers and another layer of powder is then spread and binder is added. Over time, the part develops through the layering of powder and binder.
Binder Jetting is capable of printing a variety of materials including metals, sands and ceramics. Some materials, like sand, require no additional processing. Other materials are typically cured and sintered and sometimes infiltrated with another material, depending on the application. Hot isostatic pressing may be employed to achieve high densities in solid metals.

Direct metal laser sintering (DMLS) Is an additive manufacturing technique that uses a laser as the power source to sinter powdered material (typically metal), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
.ss. Metal powder (20μm diameter) without binder is completely melted by scanning of a high power laser beam. The density of a produced part is about 98 %. SLS has about 70 %. One advantage of DMLS compared to SLS is the small size of particles which enables very detailed parts.
Working principle:
Direct metal laser sintering (DMLS) is an AM process by which digital 3Ddesign data is used to build up a component in layers by depositing metal material.
The system starts by applying a thin layer of the powder material to the building platform
After each layer, a laser beam then fuses the powder at exactly the points defined by the computer-generated data, using a laser scanning optic . The platform is then lowered and another layer of powder is applied . Once again the material is fused so as to bond with the layer below at the predefined points resulting in a complex part. Thereby not only the part but also the final material is created in the process and defines the unique characteristics of this technology. Every single welding line creates a new micro segment of the final part and can therefore be monitored. Stacking all monitoring information on top of each other, we can visualize a 3D model of the part quality.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Editor's Notes
Fused Filament Fabrication (FFF)
A key principle in 3D modeling is “divide and conquer.” It means that when modeling a complex real world object, we should divide it into smaller geometric shapes and then design these smaller units individually. In the final step, we should put these small units together. This makes modeling a complex object easy.
Applying this principle to the wrench, we divide it into three basic units:
The ring
The handle
The jaw
We will start by designing the ring.
The ring of a wrench can be approximated by a solid circular disk with a hollow circular area in the middle.
To create this shape, we will first drag a cylinder from the Basic Shapes panel to the workplane. You will notice that the cylinder has five white square handles, four of which are on the plane and one of which is above the cylinder.
The four handles on the plane can be used for adjusting the cylinder’s length and width. We want our ring to have a diameter of 25mm. Therefore, drag the square handles till the cylinder has a length and width of 25mm.
The one above the cylinder can be used for adjusting its height. We want our wrench to have a height of 4mm. Therefore, click the handle with the left mouse button and drag it down till the cylinder has a height of 4 mm.
Tinkercad operates on the principle of Boolean design, which means it allows you to subtract objects to create hollow areas or add objects to join two shapes. In this case, we will need to use subtraction to create the circular hole in the middle of our ring.
To use the alignment tool, select the cylinder shaped hole by left clicking. Now press the shift button and select the solid disk. If you do this correctly, you will see that both objects are now simultaneously selected and highlighted.
Press the Align button on the top menu (marked with a blue rectangle). Black alignment handles will appear on the workplane. Click on the appropriate handles (also marked with blue rectangles) to bring the solid cylinder in the middle of the solid disk.
As with the ring, we first need to create a circular disk of diameter 30mm and height 4mm. We have done this before, so you should be able to do this step without much problem.
To create the jaw like shape, we will use the basic shape called “Polygon”. Drag the Polygon to the workplane, select it, and turn it into a hole (as we did in Step 2). Now position the Polygon and adjust its dimensions.
If you are planning to use the wrench from this Tinkercad tutorial for household repairs, you can choose the dimension of the corresponding nut and bolt. We will use a 15mm jaw and adjust the width of the polygon to 15mm accordingly.
Make sure the polygon is aligned with the center of the disk by using the alignment tool.
It’s time to do some subtraction magic. Select both the polygonal hole and the disk by holding shift and selecting both. When they are selected simultaneously, press the Group button on the top menu (marked in the blue rectangle).
First, position the handle so that it goes a little bit into the body of the ring.
Select the handle and the ring together and align it so that the handle aligns with the center of the ring. Now press the Group button. This should merge the handle and the ring into one continuous unit. Notice that the merged unit now has a single color instead of two colors.
The jaw is facing the wrong direction. We need to fix that by rotating it. To rotate the jaw, first select it. You will see that in addition to the white square handlesfrom before, there are three curved handles with double arrows (marked in blue rectangles).
These are the rotation handles. Use the X-Y plane rotation handle to rotate the jaw so that it faces the direction shown in the figure below
Now let’s add the jaw to the previously merged unit. The procedure is more or less the same as what we used for adding the handle and the ring.
First, drag the jaw and position it so that the handle goes a little bit inside the body of the jaw. Select the jaw and the merged unit simultaneously and align them so that the handle aligns with the center of the jaw. Press the Group button to merge them.
You should now have a complete wrench on the workplane. Isn’t that awesome?
You might want to change the color of the wrench because an orange wrench just doesn’t look right. A wrench should be gray, right?
