CNC Machining VS 3D Printing

CNC machining is a type of subtractive manufacturing process that carves out the needed intended product out of a block of material and 3D printing is a kind of additive manufacturing process that builds the final product layer by layer. There are several similarities as well as differences between these two manufacturing methods.

Required Material and Waste Produced

The essential difference of CNC machining’s subtractive manufacturing process and 3D printing’s additive manufacturing processes suggests that they are compatible with different materials and produce a distinct amount of waste. Since CNC machining involves only carving the shape out, it has a wide range of material options from plastic, metal, wood, wax, and almost any kind of material. On the other hand, 3D printing has more limited available choices. In general, the common 3D printing materials are mostly only plastics such as PLA and metals such as aluminum.

In addition, due to the fact that CNC machining carves the intended product out of a block of original material, it usually produces wastes that can hardly be recycled. However, since 3D printing creates the product out of scratch, it does not leave much waste after finishing building the model.

Size, Accuracy, and Time

The products made by CNC machining and 3D printing are distinct in terms of size, accuracy, and the time it takes to manufacture them. more

Projectors’ Era is Coming Four Recommended Projectors for 2019

An Ultimate Guide to Whatever Kind of Projector You Need

Have you ever wanted a movie theater experience in your own home, without the expensive cost of a giant-screen television set? Do you want to experience what it’s like to play a game on a big screen?Or do you want to be able to watch movies while you’re traveling or in the outside? If so, a projector is your new best friend. The big question is, how do you find the right projector for you? You can find a wide variety on the market, each with its own features, pros, and cons. Therefore, the process of buying a projector can be very tedious and difficult especially when you don’t know what you want from the projector.

In this article, you will find that we have selected the recommended four projectors. Each projector has its own outstanding features and the most suitable scene. Therefore, when are you going to buy, you can read our projector recommendations. It will tell you more about the knowledge of the projectors and how to find a projector to meet your personal requirements perfectly.

Best Projector for Beginners——LG HU80KA

Most people shrink back at the sight of the difficulty of projectors’ setup. Like trying to wire it up a to a ceiling mount or finding a table of perfect height and distance to get a clean image, we won’t pretend that getting a projector installed is an easy thing. Thankfully, LG HU80KA solves these problems for you.

Comes in a compact, portable form factor, the HU80KA doesn’t require a table or stand, making it easy to wire, position, and setup. A laser-based light source, full 4k, HDR10 resolution and 2,500 lumens of brightness facilitate cinema-style viewing, with the ability to project a 150-inch screen. You can even stream audio via Bluetooth without a home theater receiver. If you want a huge picture but don’t want to break out a stud finder and mounting brackets when it arrives, this is the best projector you can buy. more

Surface Mount Technology in Printed Circuit Boards

What is SMT? Why SMT? And Who should you choose?

What is SMT?

In order to get the complex circuitry fitting in the small spaces, surface mount technology (SMT) is born to mount the components onto the circuit board rather than putting wire leads into holes drilled in the circuit board. The components made by SMT occupy less space and a single component can perform multiple tasks. In 1980s, SMT become popular since the surface mount devices (SMD) is introduced. Today SMT is the main technology used for electronics manufacturing. more

A Brief Overview of 3D Printing

3D printing lets designers generate complex shapes and parts - many of which cannot be made by conventional manufacturing methods. By the natural laws and regulations of physics, making through additive strategies implies that complexity doesn’t possess a cost; elaborate product designs with complicated style features now cost as much to produce as simple product patterns that follow all of the traditional rules of regular manufacturing.
