Covestro acquires DSM Additive Manufacturing, outlines plans to “bring benefits of SLA to DLP”
0Shares
German polymer manufacturer Covestro has completed its acquisition of DSM’s Resins & Functional Materials unit, including its 3D printing offering, and the ex-DSM team is working to “bring the benefits of SLA to DLP” with a new line of Somos resins.
According to what was DSM, and is now Covestro, the adoption of DLP/LCD 3D printing is growing rapidly thanks to the technology’s high throughput capabilities, but existing materials are proving to be a barrier to scalability. To prevent the distortion that’s often seen in prints from larger 8K machines, the firm is now working on a new range of ‘hybrid resins’ with an SLA-like chemistry, that could yield parts with significantly reduced shrinkage.
“What we’re seeing in the DLP world is that these printers were very small, but they’re getting much larger now,” explained Andrew Graves, Equipment Partnership Manager at former-DSM-now-Covestro. “DLP is getting to 4K and 8K, and the LCD printers are kind of unlimited about how big they can get.”
“As printers get larger, you’re going to get distortion and a lot of curling using current materials,” he added. “So we are looking at bringing our expertise in SLA hybrid materials into the DLP and LCD world for end-use, and specifically, for larger parts that need to be accurate and conform to an engineering drawing.”
Covestro has now completed the acquisition of DSM’s Resins & Functional Materials business. Image via Covestro.“We are bringing our expertise in the engineering polymers field to DLP and LCD printers.”
An expanded polymeric portfolio
Based in the Dutch city of Geleen, DSM’s former 3D printing materials division was acquired by Covestro in a deal announced last year, and formally absorbed into its wider business on April 1st 2021.
Prior to its acquisition, the subsidiary had built up a broad material portfolio, purchasing part of Clariant’s filament and pellet range in June last year, that will now serve to supplement Covestro’s burgeoning product line-up.
The ex-DSM division’s range already caters for a broad church of printing technologies, and includes everything from FDM-suitable filaments to SLS-ready powders. Over the last two years, the team has developed glass-filled 3D printing pellets as well as new sustainable materials, debuting its bio-based EcoPaXX AM4001 GF polymer in November 2020.
Elsewhere, leveraging its growing expertise in large-format printing, the former DSM team has contributed to a number of eco-friendly infrastructure projects, including a Dutch 3D printed footbridge built entirely from recycled materials. Moving forwards, the team continues to encourage more sustainable production, and is currently developing a Life Cycle Assessment (LCA) tool for assessing the green merits of its upcoming products.
Levelling-up DLP printing
Another core component of the team’s future material strategy, lies in its analysis of trends within the DLP and LCD 3D printing segments. According to the company, light-powered machines have grown larger to the point that there’s now a demand for resins that offer reduced distortion, yet there aren’t any materials that offer SLA-like stability on the market.
“All SLA materials that are available today from either Covestro (formerly DSM) or other companies, consist of a hybrid chemistry which is an epoxy acrylate combination with two materials and two photo-initiators,” explained Graves. “It gives you tough materials with very low shrinkage, which is important when you’re building large parts.”
By launching DLP resins that feature a unique acrylate/epoxy-based chemistry, the ex-DSM team is therefore aiming to corner a market niche for DLP/LCD-optimized hybrid materials.
Under DSM, the company previously dipped its toe into the market with the launch of the non-hybrid Somos QuickGen 500, a dedicated DLP polymer with enhanced flexibility, and it intends to supplement this portfolio moving forwards.
In terms of speed, the resin is reportedly capable of printing twice as quickly as other similar polymers, making it better-suited to functional prototyping applications. Later this year, Covestro (formerly DSM) also plans to launch the Somos PerFORM HW, a new hybrid material that could take DLP to the next level by bringing true SLA functionality to market.
Previewing the PerFORM
The former DSM team has worked closely with various 3D printer manufacturers to optimize the performance of SomosPerFORM HW. During initial testing, the material reportedly demonstrated an SLA-like tensile strength after post-curing of 80 MPa, in addition to an extremely high heat resistance to temperatures up to 260°C.
Having successfully tweaked the formulation of its new material based on the feedback gained via test prints on their partners’ machines, the team is lining up a Q2 2021 release for its first truly-hybrid DLP polymer.
“As far as we know, there’s nothing like it,” concluded Graves. “If you look at the PerFORM HW, there are competitive versions of PerFORM for the SLA, and there are similar materials in the DLP world, but there’s nothing that is based on this hybrid chemistry, which offers the same low shrinkage and high accuracy in the DLP world.”

3D printing using the new MOVINGlight technology
Alla Aspidova, Ivan Papusha – [email protected]
Published in issue: Control Engineering Russia August 2017
PDF version
Today, additive technologies are confidently gaining a place in the manufacturing process. A 3D printer has long ceased to be a toy in the hands of experimental enthusiasts and has become a means of production, or at least a technological link - for example, GE successfully uses metal 3D printing in the production of gas turbine engines. And thanks to the creation of new materials, even well-known technologies such as stereolithography (SLA) or plastic filament deposition (FDM) can gain a second wind and open up more applications.
If 10 years ago in Russia 3D printers were used only in some closed enterprises, then over the next decade we may well see a change in the usual cycles and principles of production due to the introduction of additive technologies on an industrial scale.
In addition, we are already actively working on the standardization and regulation of the use of 3D printers in production at the state level.
Ostek-SMT LLC not only offers equipment for industrial 3D printing, but also conducts its own research, which makes it possible to profitably apply existing technologies to solve complex problems. This article will take a fresh look at stereolithography, or 3D printing with a light-cured photopolymer.
Benefits of MOVINGlight technology
Stereolithography started the development of 3D printing technology. She appeared in the 1980s. in the United States, then used in the USSR. Its essence is quite simple: the model is built in a tank with a liquid photopolymer, the product is virtually divided into layers by means of software, and an ultraviolet laser installed above the tank illuminates the photopolymer according to the shape of each layer. In the 2010s the technology has been upgraded: instead of a slow laser, MOVINGlight uses a fast ultraviolet projector, which, by moving, allows you to increase the speed of production up to ten times.
In addition, a wider range of applied materials has become available: from high-temperature plastics to bio- and oxide (technical) ceramics (Fig. 1). The result of printing using MOVINGlight technology is precise plastic and ceramic products (up to 0.1% of linear dimensions) with high surface quality: Ra is 0.5–5 microns. The hardware resolution of such a 3D printer makes it possible to print 605 × 605 × 1016 dpi (resolution of the order of 40 microns).
Fig. 1. Working area of Prodways 3D printer powered by MOVINGlight technology
Due to the size of the printing area, MOVINGlight technology can be used to print both small and large items - up to 800×330×400 mm. The variety of available materials allows the use of a multifunctional printer, and also allows the implementation of effective solutions for layer-by-layer additive growth in many areas, including biomedicine and industry (table).

Applications
Due to the material characteristics listed in the table, MOVINGlight technology is suitable not only for printing high-precision prototypes (Fig. 2), but also for the creation of industrial tooling, and in some cases even final products.
Fig. Fig. 2. Functional prototype printed from ceramic-filled plastic
Let's look at examples of the use of this technology in such areas as plastic printing, injection molding and 3D-MID. Prototypes printed using MOVINGlight technology are already being used as master models for silicone injection molding, but the most interesting application in tooling is direct 3D printing of plastic molds for injection molding of plastics, as well as for vacuum forming. For these tasks, the temperature-resistant material PLASTCure Rigid 10500 with the addition of ceramic powder is used.
The temperature that these molds can withstand depends on the geometry of the molded part and the cooling channels. The bending heat resistance at 0.46 MPa ASTM D648 of this ceramic-filled plastic is +132 °C, however after hardening it is possible to obtain a bending heat resistance at 0.46 MPa ASTM D648 of the order of +260 °C.
Prodways, a 3D printer manufacturer, conducted an experiment to test the capabilities of MOVINGlight technology in the production of molds for small-scale injection molding.
PLASTCure Rigid 10500 was printed into a two-part plastic injection mold for 3D printing. The objective was to produce at least 250 castings from polypropylene and polyformaldehyde and at least 30 castings from glass-filled polyamide. The dimensions of the parts are small and medium, in this case, injection machines for 50–100 tons were used. The specified number of castings was obtained, and the experiment was recognized as successful (Fig. 3).
Fig. Fig.
3. PLASTCure Rigid 10500 ceramic-filled mold (a) and castings produced in this mold (b)
After that, casting tests were carried out on a wider range of plastics. As a result, several hundred castings were obtained from polypropylene (PP), polyethylene (PE), polystyrene (PS), ABS plastic (ABS), thermoplastic elastomers (TPE), polyformaldehyde (POM), polycarbonate-ABS alloy (PC+ABS). ) and polyamide (PA). Also, several dozen castings can be made from glass-filled polyamide (PA+GF), glass-filled polyformaldehyde (POM+GF) and glass-filled polycarbonate (PC+GF).
The advantage of MOVINGlight technology is that a pilot batch of plastic castings can be produced quickly and with minimal financial and time costs for the production of tooling. The mold is designed in CAD and then simply printed on a 3D printer. As a result, pilot production can be reduced from several months to one week with a quality of products similar to castings in aluminum molds.
Another available use of MOVINGlight in combination with PLASTCure Rigid 10500 ceramic resin is printing tooling for vacuum forming a limited series of products or a pilot batch.
The advantages in this case are similar, an example of such an application is shown in Fig. 4. The ability to print mesh internal structures of the tooling for molding allows it to be vacuumed more evenly, which, in turn, allows for a closer fit of the heated sheet of material and a higher quality product. This tooling is made in about two days and can be used for a range of 10 to 100 moulds.
Fig. 4. Products produced by vacuum molding on a tooling made of ceramic-filled plastic PLASTCure Rigid 10500
Ostek-SMT conducted its own experimental work on the use of MOVINGlight technology in creating three-dimensional schemes on plastics (3D-MID), which consist of molded thermoplastic bases with integrated connection system. Products on plastics make it possible to simplify the design, reduce the number of assembly units and the weight of the product, as well as increase its reliability. In addition, they are more environmentally friendly than conventional PCBs, although they are not a replacement, but rather a complement.
Key markets for 3D-MID technology are automotive electronics and telecommunications. Apart from these, 3D-MID is also suitable for computers, home appliances and medical technology.
There are several prototyping steps between prototype and series production, but for single or small batch production, prototyping is usually either impossible or expensive. This problem can be solved with the help of MOVINGlight technology.
Fig. Fig. 5. Dielectric constant of PLASTCure Rigid 10500
PLASTCure Rigid 10500 was chosen for printing prototypes of products with three-dimensional schemes (Fig. 5), which, in addition to high temperature resistance, has acceptable dielectric constant. Plastic bases for products were printed from it, and a three-dimensional pattern was applied to the base using AJP (Aerosol Jet Printing) conductive material spray printing technology, in this case silver spray. On fig. Figure 6 shows an example of a housing prototype with a working Wi-Fi antenna applied to it, manufactured at the Ostek-SMT production center using MOVINGlight technology.
