Like other printer types, you can 3D printer to print an object. The extruder in the printer warms up a plastic filament and gets squeezed out through a small outlet. The extruder group is joined to a carriage that can be correctly traveled in three dimensions in any one of the below directions. The first option is it moves on an X-Y-Z axis available in many consumer printers and the second option is complicated movements like five, six and delta axis.

3D printing pen gains similar popularity like 3D printers. It is low-powered and easily holds in your hand. The main highlight of this pen is it permits you to make free form models with the imagination and a stable hand. popsci.com explains the different areas where the 3D pen is used effectively nowadays. The site also contains the detailed reviews of the recent 3D pen models.

3D pens are typically available as artistic devices. It provides a separate medium for 3Dsculptors. It is also used for repair and decorative purposes, or you can use it along with 3D printers to combine smaller pieces together into larger designs. For artistic purposes, 3D pens make thin plastic strands precisely similar to those emerge from 3D printers.

The 3D printer is precise and rigid and perfect for prototyping parts, and a 3D pen is creative and fluid. Printers need an entirely designed 3D file to begin any printing job, whereas you can start the drafting with a 3D pen with a small imagination.

There are several 3D pen models available in online. You must choose the best models that offer high-quality results. Some of the top design pens are explained here.

The 3Doodler is the initial 3D pen model launched in the market using the standard technology. The first models of the 3Doodler pen have some flaws, and the recent 3Doodler models have rectified some of the drawbacks of this model. The size of the pen is thin like the whiteboard marker size. It is very easy to control, and the double tap feed button allows constant flow.

The Samto 3D pen is thinner when compared to the first generation 3Doodler model. It has plenty of color options apart from black. It comes in fast as well as slow speed control like the temperature control of 3Doodler. It is quiet and slender and automatically comes into standby mode even after left idle for five minutes.

The Scribbler 3D pen is a stylish and an ergonomic design. The large LED screen shows the speed and temperature settings of the pen. The six-speed settings of this model permit to choose the best match based on your personal ability.

The MYNT3D 3D pen is new model launched in the market recently. The features of this pen improve the user experience. The OLED display of the pen facilitates observing the heat, which can be modified from 130 to 240 Celsius with a small increase. Most users of this pen state that it is thin when compared to other similar pens on the market. It is easily affordable, lightweight and easy to grip and control.


CFD or Computational Fluid Dynamics stimulates the flow of gasses and liquids by using numerical calculations. The CFD analysis starts in the design process before the first prototype is built. The development in technology promotes better design in a faster and cheaper way. Multiphysics can be called an advanced CFD that combines multiple physics along with an imitation of real behavior in an accurate way possible. Take the instance a merger of fluid mechanics, chemical kinetics and heat transfer required to fuel a reactor. It is here that ESI-Group CFD Solutions comes handy. Here the simple solutions are provided for both simple physics and complex physics. elearningindustry.com provides material on CFD.

Industry leaders from across the globe are looking for innovative simulation applications for their products. Industry experts like WiTricity have revolutionalized the wireless power transfer. Similarly, the Research And Development Wing of Cypress Semiconductor are using simulation apps as their latest means of communication between the production team and modeling experts. These are just a drop in the ocean and there are more success stories available in online magazines.

Simulation is no more a subject restricted to R&D specialist; it has gone beyond and is used by everyone. The advent of low cost and customized simulation tools has removed the roadblocks making simulation accessible to everyone. The simulation apps are becoming simpler with improved R&D. A wide range of industrial and consumer products are using simulation apps to enhance their design. With the emergence of ready to use apps being distributed to other departments, there is no more a need to run simulations repeatedly for every case.

Advantages of simulation apps
The biggest advantage of the system is the easy use of apps across customer support teams without the need for any expertise and at a partial cost of a full-featured model. The apps can be created and distributed in a single software environment. For those interested in power supply unit design, the WiTricity wireless power transfer could come handy. Under the Multiphysics Simulation Graphene is an important topic that has provoked interest on how it could be applied in the real life scenario.

Without an innovation product launch cannot happen. Only scientific breakthroughs and technological innovations can give birth to new products. The knowledge and experience of a bunch of people ranging from design engineers to technicians are responsible for developing a successful product. It is the R&D department that tests and analyze the products through advanced computer aided tools or CAE. With the help of CAE the engineers build models to understand the performance in the real world scenario.

Simulations are conducted with the help of physics models for product updates, customization, exploration of materials and designs. In earlier cases only a small group of experts were adept in creating models and making design modifications giving rise to bottlenecks. Now the computerized tool has an elaborate user base.

The higher use of multiphysics simulation has led to an increase in innovativeness and productivity. The R&D engineers use Application Builders to share their expertise on simulation with other. This way it is easier and faster to build an interface.

wifi extender

Using Wi-Fi has become something very common these days. Homes, offices and other business establishments need Wi-Fi connections for many reasons. If your router does not receive ample of Wi-Fi signal, then it is better to make use of Wi-Fi range extender. As the name says, this device simple extends the strength and signal of your existing Wi-Fi. This device helps to use Wi-Fi from different rooms and places within your property. You may log on to sites.google.com/site/wifiextendercentral/ to know the best extenders for your home. You can read more useful and exciting articles on Wi-Fi extenders at digitaltrends.com.

A good device will excel in many areas such as speed, portability, range and physical connections. The signal range will vary from device to device. You should know the range by measuring the size of your home. A small home requires a device with a small range. Remember that device with higher range will be expensive. Choosing a device with higher range more than what is required can be a waste of money. Apart from the range, you should also check whether the extender can allow you access the Internet with good speed. You should choose an extender that allows you use the Wi-Fi with good speed. Some device can slow down the Wi-Fi performance.

Device with better portability makes it easy to set up and install at various points or locations. You should buy a wireless extender, only if the W-Fi is working properly. Spending so much money of extender, without a good Wi-Fi device is nothing but a waste of money. You should also check whether the router is optimized to your home settings.
