Why CNC Machining May Be Better Than 3D Printing

3D printing (additive manufacturing) refers to the fabrication of a component by adding successive layers of materials on a mould until the part is identical to a computer model. CNC machining (subtractive manufacturing) refers to the fabrication of a part by removing layers of material from an existing metal billet. A computer programme also controls subtractive machining. This article discusses why it may be better for you to specify that CNC machining should be used to make the equipment components that you need instead of using 3D printing. [Read More]

When to Use Acrylic Sheets Rather Than Glass

Acrylic and glass may look very similar to you, but the materials are actually very different. In some areas, it may be beneficial to use acrylic where you would expect to find glass, such as for windows and even picture frames. Note when it's good to choose acrylic sheets rather than glass for your home, office, storefront, and other such applications. 1. Vibrations Acrylic has a higher impact resistance rating than glass, so it should be used where heavy vibrations may be a factor. [Read More]

Home Solutions For Welder's Flash

Professional welders do not stare at the welding flame with naked eyes. They wear special goggles to protect their eyes against the bright light produced.  This is because they are aware of the harm that these lights can cause and so should you.  By looking directly at the flame, you might suffer from welder's flash, or a flash burn. It is a painful inflammation of the transparent layer that covers and protects the outer part of the eye, also known as cornea. [Read More]

How to Prevent Porosity When You Weld Aluminium

Some DIY welders discover that the aluminium product that they have welded is porous after the fabrication process. This porosity can cause the material to leak in case it is used to transport a fluid or gas. This article discusses how you can prevent porosity from afflicting the aluminium that you have welded in your home-based workshop.  Clean the Aluminium Hot aluminium readily absorbs hydrogen gas. This trapped gas forms pores once the sheet metal cools down. [Read More]
