Introdución ao Prototipado Rápido

Os prototipos xogan un papel importante na investigación, desenvolvemento e estudo. Estes prototipos desenvolvidos axudan ás probas de preproducción e axudan a detectar posibles problemas causados ​​por erros de deseño. Xerar un modelo anterior foi un proceso moi caro e tamén un proceso lento. Pero co control numérico por computadora (CNC), a velocidade de desenvolvemento de prototipos aumentou. Con prototipado rápido, este prazo incluso se reduciu de poucos días a poucas horas.

O prototipado rápido é un proceso de fabricación aditiva que xera un modelo de obxecto directamente a partir do modelo CAD, creándoo en capas. Este equipo informatizado emprega un modelo tridimensional de fundición a partir dun deseño CAD.

Dependendo das necesidades, hai diferentes tipos de prototipado rápido. Entre estes están os métodos empregados por estes sistemas para crear capas. Aquí están algúns dos principais tipos de prototipado rápido:

Estereolitografía (SLA)

A estereolitografía usa a luz ultravioleta para curar a capa de polímero acrílico líquido por capas nunha plataforma en movemento e, despois de moitas capas, crea un prototipo da forma desexada. Este proceso realízase nun dispositivo cheo de IVE cuberto cun polímero de acrilato líquido quentado pola foto. A estereolitografía é unha das formas máis comúns de prototipado rápido, debido á súa precisión (tolerancias = 0,0125 mm), menos tempo (dependendo do tamaño e complexidade da peza) e dos casos nos que os detalles son delicados e a súa xeometría difícil de procesar.

Modelado de depósito fusionado (FDM)

Modelado de revestimento de fusión, tamén chamado FDM, é unha tecnoloxía de prototipo rápido usada habitualmente para converter debuxos CAD en partes físicas. FDM é unha marca comercial de Stratasys e foi desenvolvida por S. Scott Krump.

FDM opera co principio “aditivo”, que extrae o material en capas. O plástico ou a cera fúndese e licuouse na cabeza de extrusión e esprázase a través dunha boquilla. A boquilla faise para moverse por un camiño identificado por un deseño CAD para obter unha peza. Deste xeito, extrúese unha capa e logo déixase de xeito que se extrue a seguinte capa sobre a primeira ata que se constrúa un prototipo enteiro cunha soa vez.

Aglomeración láser selectiva (SLS)

A aglomeración láser selectiva usa o principio de sinterización. A fusión é un proceso de calefacción que impide fundir e produce unha masa homoxénea. Os polvos metálicos ou non metálicos SLS son sinterizados usando un láser programado por CAD que fusiona de forma selectiva o material en po.

Hai algúns outros tipos de prototipado rápido dispoñibles, como por exemplo; Produción de artigos laminados, impresión 3D, endurecemento de bases sólidas, fabricación óptica e procesamento fotoquímico.

O prototipado rápido proporcionou aos deseñadores unha serie de vantaxes. Os deseñadores poden ollar os seus detalles e, se ocorre un erro, poden resolvelo facilmente. Ademais do uso industrial, tamén forman parte da produción. Este proceso de desenvolvemento proporciona mostras en branco para uso en fundición. O RP tamén difundiu a ciencia biomédica.

Vantage pro anemometer

I could talk all day long about the weather. The weather is one of my favorite subjects and I learned how I grew up and then online. Yes, I also bought books about it. It’s one of those things that, as you get older and start a career, I hope you would have done it instead of your current career. I would have liked to become a meteorologist, but I did my best. I have my own weather station with which I can predict my local climate.

What’s really fun is when I can watch my weather gear and get the same results as the boys on TV and they have the National Weather Service (NWS) to get their information. All my neighbors come to see me when they have questions about the weather and what to expect the next day. If they leave the city, they call me to know what I think of the weather in a city 400 km away. Usually, I just tell them to look at the weather map to get this information because I can only predict the weather here in my city.

You know that? You could do the same thing. It is very amusing and comforting to know that the weather will change without having to run on television or wait for news to arrive to get the information from my weather forecast. To start planning and knowing your own weather, you only need a few simple weather instruments, such as an indoor and outdoor thermometer, a barometer, a rain gauge, a wind vane and an anemometer. You’ll learn more tools as you enter more, but for now, that’s all you need. Oh yes, and access the NOAA or NWS weather charts on your computer.

The thermometer gives you the ambient temperature. We have all grown up with a kind of weather thermometer all our life. The barometer provides a measure of atmospheric pressure that tells you when the weather is changing or is likely to change very soon. The rain gauge captures only the rain, when it falls, and tells you how much it has fallen on your area. The wind vane and anemometer are two instruments that tell you where the wind is coming from and how fast it is blowing. There are other instruments that you can use if you wish, such as a hygrometer or a psychrometer. Both measure relative humidity, which you will want to know later. You can get all these components one at a time or you can do what I did and just buy a residential weather station that already has it all and comes in a box. Unpack it, take out the various sensors and instruments outside and install them, put batteries as it is wireless, enter and configure the software on your computer. It took me about an hour to do everything. Now, I am the neighborhood meteorologist.

There are thousands of amateur meteorologists around the world and everyone exchanges information and keeps weather records for their communities. Although most have not done formal studies in meteorology, the fact is that they love it and they have every interest in observing the weather.

If you are looking for good wireless weather stations at a good price, let me make some recommendations. Remember that prices go from the lowest to the highest, and the big difference is the degree of technological advancement used in the instruments. Most cheaper stations will work very well, especially if they are just starting to become a climate mistake.

For more expensive models, take a look at the Davis Instruments 6152 Wireless Instruments Vantage Pro2 with standard radiation shield. Excellent technology can be obtained for about $ 750. Another highly respected and highly recommended high-end weather station is the Davis Instruments 6153 Vantage Pro2 with a 24-hour fan-assisted radiation shield.

For the best and cheapest weather stations, consider the P3 INTERNATIONAL METRIC Professional Weather Station or the TALKING La Crosse WA-1340 Weather Direct Wireless Weather Station. Oregon Scientific also manufactures fantastic weather weather stations like Honeywell

4.Expansibility:

You will have to buy some types of products that can be expanded. Your requirement and need may change in future. So, you will have to open the scope as well. You can add some feature to it in future. So, the expand-ability option is very much useful and beneficial.

5.Durability:

You will also have to check about the durability of the weather station. Some inexpensive stations are made with low graded plastic materials. These can be deteriorated easily. So, you will have to buy a well-built weather station. You will have to stay away from the all-in-one housing weather station. If one sensor fails, then you need to replace all of them at the same time.

6.Good display:

You will have to check the good and wide display screen of your weather station. A good display can read well from any angle. You can also go for the backlit feature so you can see it even in the dark environment.

The setup process of the weather station is not at all a long process. All the instructions are given therein straightforward manner. So, you do not need to face any kinds of hurdles in order to install it in your house. After buying this, you do not need to rely on the forecasts of the nearest weather station.

Functions of a College Advisor

college advisor is a type of counselor working with students at the college level. One of the roles of a college counselor is to help students to choose a major and a minor and making sure they have met all the requirements to graduate with a major in their field of study. Most colleges recruit highly skilled professionals to take on these roles and task the professionals to keep on teaching while interacting with students during office hours every semester.
Below are some of the responsibilities of a college counselor:
Provide career guidance
Providing career guidance is one of the responsibilities of college counselors. Students join colleges and universities to acquire the education required to pursue specific careers. Nevertheless, most students are not aware of the career they would like to pursue, or they are planning to change their major. College counselors can aid students in finding out career options which are suitable for them by engaging in conversations and making use of assessment tools which can help students to determine the job factors that are essential to them and also analyze their traits to find the most appropriate career option.
Inform students of policies
College and universities have a set of rules, regulations as well as policies. College counselors are professionals who have a deep understanding of the college policies and are in a position to explain them to someone else in a clear way. For instance, most colleges and universities ensure there are no restrictions when a student seeks permission not to physically attend a given number of classes without showing their grades on their transcripts. Nevertheless, when a student is not well informed of all the options when not doing well in a class, then this can make a distinction between a student receiving a poor grade on their transcript and those not receiving the same.
Monitor student performance
Advisors are tasked with the responsibility of keeping case files and also to monitor every student academic performance. This can result in a considerable workload, especially in colleges with hundreds of students. But nowadays, this process is somehow more straightforward due to the use of technology. Advisors can inform students of the available services for remediation as well as academic assistance. They also make referrals to other professionals on varsities when students have academic, attendance, and other personal issues which may demand assistance.
Inform students of resources
College advisors act as an intermediary between students and resources. They ensure students are up to date with other opportunities like internships or university employment opportunities. They offer contact information and provide the necessary guidance to students regarding the available school resources such as financial aid, student affairs, as well as mental health counseling. Advisors have many links across the entire campus, and this makes it possible for students to use them as a resource when seeking solutions to all sorts of problems. Advisors have several roles and responsibilities, but their primary function is to help in ways which enable students to see an improvement in their performance, thereby succeeding in their career paths.

All About Shower Glass Panel

Are you tired of your old shower curtain in your bathroom?
Is it laden with slimy things and mold that can not only make you sick but also family? Don’t you want to make your wash space along with the bathroom a much clean, fashionable and mold-free environment? If your answer is yes to any of the above-mentioned questions, then let me tell you that you can make it by installing a shower glass panel.
No matter how your house is (newly constructed or its fiftieth year of existence), adding it can be a great idea. A lot of people are becoming a member of the revolution of glass enclosure in the wash space. Unlike the bathtub or shower of the past, the glass panel doesn’t smell nor do they aid in a breeding ground for the growth of mold. They make many positive contributions to your house especially your bathroom.
The location of the proposed glass panels does not depend upon the design of your house. It will be perfect no matter whether your house
has Modern Age design or Victorian. The only limitation of the glass panel is the budget, which is the only thing that can stop you from buying a glass panel for your bathroom. Another limitation is the imagination and skill level of the installation crew. You should find the best professional for doing the job. The skill of the professional will determine the work of your glass panel. There are wide options available for glass. The main categories are Tempered Glass, Laminated Glass, and Cast Glass.
They come in many different qualities and colors. So, it will be easier and better for you to choose from the available stocks and a wide range of options available. Another important thing that one should not forget while hiring a Shower Glass Panel contractor is that there will be hardware that will hold the glass in its place. A little mistake in the selection can be very expensive as it is the frame or backbone of the panel. There are two choices in the selection of hardware. Framed Unit and Frameless Unit are the two basic hardware that is required to hold the Shower Glass Panel.
The framed unit is provided with rails on which the glass slide open and shut. The frameless unit has no frame but has door hinges and brackets along with silicone for holding the glass panel on its place.
