New printer for serial metal 3D printing in MCAE

MCAE Systems has launched a new printer for serial 3D printing of metal parts on its own branch in Plazy near Mladá Boleslav. The Shop System from the American company Desktop Metal enables the production of up to 70 kilograms of metal parts per day using a method called Binder Jetting. At the same time, it does without lasers, complicated print preparation and demanding postprocessing. Desktop Metal is one of the most active and fast-growing start-ups in the field of 3D metal printing.

It was founded in 2015 by major players in the field of advanced manufacturing, metallurgy and robotics. The company’s goal is to address unresolved challenges in speed, cost or quality, and to support the importance of using 3D metal printing as a production tool worldwide. Desktop Metal is represented in the Czech Republic and Slovakia by the company MCAE Systems, which has the equipment Stu­dio Sys­tem 2 and Shop System, thanks to which it itself provides custom 3D metal printing services.

Shop System was designed as a solution for serial production of small to medium-sized metal parts without the use of tools. Compared to laser 3D metal printing systems, this machine prints fully homogeneous parts for end use, with excellent surface finish and resolution. It produces high-quality metal parts 10 times faster than laser sintering technology. It also boasts a speed of up to 700 cm³ / h, which means that it is able to produce up to 70 kg of metal parts per day.

With simple operation via a user-friendly interface, you can process several complex parts at the same time, without the need for lengthy setup. Shop Sys­tem ensures perfect surfaces, the finest details and control of binder application, all while maintaining a high printing speed.

In the device, the parts are perfectly supported by the surrounding powder during printing, and at the same time the corresponding sintering supports are also printed together with the parts. It is therefore not necessary to spend many hours mechanically removing the support structures that are typical of laser systems. The finished parts are prepared for the customer directly from the sintering furnace.

The Shop System includes all the equipment needed to get started with Binder Jetting technology – from printing to sintering. It is designed with a variable building space in several configurations, which allows it to be adapted and grow exactly according to the needs and volume of production.

Soft­wa­ro­vá apli­ka­ce Live Sin­ter

Live Sinter software, which has been developed for more than a year in collaboration with the top Desktop Metal team in the field of materials science, works on the basis of an iterative simulation. This software is the first of its kind to be designed to enable the process to be understood and performed more repeatedly, especially with regard to users without previous sintering experience.

The possibility to refine the production of parts on the Shop System device does not have to remain only in the theoretical level. It is also possible to upload a 3D scan of the finished part to the Live Sinter software (eg from 3D skenerů from GOM, which MCAE Systems has at its disposal), from which the software again makes a “negative shift”, which can take the precision of metal part production one step further.

Serial additive production of metal parts

In cases where the manufacturer needs only a few tens, hundreds to thousands of pieces of a certain part, the Shop System fills the gap between small series production of prototypes and series production. There are several reasons why manufacturers may need fewer parts before going into series production. At the beginning of the production of a certain vehicle – even one that can eventually be produced in the hundreds of thousands of pieces – the carmaker can produce only a few hundred vehicles as a pilot series for product and market testing. Only then will it move to series production.

In another case, high-performance cars, such as the Ford Mustang Shelby GT500, are often produced in limited numbers. In 2010, Ford produced only 2,000 of these cars, which means that automakers may only need to produce a few thousand units per part. Such a situation can also occur in the case of mass-produced cars, if the part is needed only for some of them. The number of parts for the spare parts market may be even smaller – in the case of hard-to-find components for classic cars, the demand may be for only a few hundred pieces of a certain part.
