International Black Friday and Cyber Monday 2023 deals and coupon codes

We’ve been writing about international Black Friday and Cyber Monday deals and coupon codes since 2014, as US-centric promotions such as Amazon’s Black Friday and Cyber Monday deals are not always available to the international audience of CNX Software. So once again, we’ve searched at Black Friday and Cyber Monday 2023 international promotions and discount codes from specific manufacturers as well as popular online stores such as Aliexpress, Banggood, and others. Aliexpress Black Friday and Cyber Monday event Aliexpress will have a Black Friday (and Cyber Monday) event in 2023, but we have limited details at this time since it will only start on November 23, contrary to some of the other deals we’ll feature below which are already up and running.

Convert your 3D printer into a metal cutting machine with an Electrical Discharge Machining kit (Crowdfunding)

Rack Robotics’ Powercore is an Electrical Discharge Machining (EDM) kit that converts your existing 3D printer (or CNC router) into a machine capable of cutting high-precision and detailed metal parts. We’ve already seen 2-in-1 3D printers and laser engravers such as the Creality Ender 3 S1 Pro, but while this type of machine can usually cut plywood or engrave stainless steel, the laser is not powerful enough to cut through aluminum. The Powercore EDM kit changes that by enabling the cutting of aluminum parts up to 4mm thick, although aluminum sheets that are 1mm or thinner are recommended. But before we get into Powercore details, what is Electrical Discharge Machining exactly? Engineers Edge explains: Electrical Discharge Machining, EDM is one of the most accurate manufacturing processes available for creating complex or simple shapes and geometries within parts and assemblies. EDM works by eroding material in the path of electrical discharges […]
