For medium and large businesses, the E2, Pro2, and Pro2 Plus from Raise3D are still the best 3D printer options, even though there are other more expensive 3D printers designed for other purposes. For medium and large businesses, it is more important to work the budget carefully across different equipment and technologies. For example, if a business has a $1 million budget, should the business spend it all on a single 3D printer or invest in 200 or more Pro2 dual extruder 3D printers? The answer is not absolute. A business can deploy 200+ Pro2 3D printers across the entire R&D team nationally or even globally. This will ensure the business’ entire R&D team will be able to get adequate access to 3D printing and improve a variety of business operations. This includes but not limited to increasing productivity while reducing cost, shorten the product’s R&D period, accelerate production, maximize the potential of the R&D team, and more. However, when it is necessary, it is a good idea for a business to invest in metal 3D printing as well.
