Additive manufacturing continues to grow at an exponential rate, in terms of software and design tools, materials of different types and formats, production equipment, post-processing…, it is a reality and an opportunity for many companies. The development of new materials for additive manufacturing is one of the main attractions to achieve a greater offer of benefits and behaviours, broader applicability of additive manufacturing technologies and to respond to specific needs of sectors or to specific demands for technical materials.

Aware of this, BASF is betting from its Forward AM division on the development of new materials for additive manufacturing with the aim of expanding the offer of available technical materials, improving performance and behaviour and extending their applicability, as well as accelerating the adoption of additive manufacturing technologies in the industry through the use of these materials in high production equipment, through its participation in the IAM 3D HUB, where it also participates as a supplier of materials and technologies for extrusion of filaments and photopolymerization of resins. Thanks to their participation in the IAM 3D Hub, all the technical staff have exclusive access to all the 3D printing materials developed by BASF through Sculpteo, thus allowing the obtaining of 3D printed parts in different technologies and different materials in a timely manner. 48 hours. Thanks to this access, it is possible to respond to companies interested in testing different materials and comparing characteristics.

Regarding the research and development of materials for additive manufacturing, Forward AM is carrying out collaborative R&D projects with the Leitat Technology Center, founding partner of the IAM 3D HUB, to obtain new technical polymeric materials: filaments thermoplastics and polymers loaded with carbon fibres with high mechanical properties and resins with high impact resistance, high rigidity or high heat resistance. The collaboration started at the end of 2019 and, despite the outbreak of the pandemic, in 2020 BASF made four additive polymer manufacturing equipment available to the IAM 3D HUB and Leitat: two polymeric filament production equipment with double extruder, a BigRep One, with a build volume of 1m³, and a BCN3D Epsilon with a heated chamber and two Photocentric high-production light-curing resin systems, the Magna and Maximus models.

The BigRep ONE printer is a piece of high-volume industrial construction equipment using Fused Filament Fabrication (FFF) technology that enables large parts to be manufactured for industrial applications. This equipment is prepared to manufacture with PLA, PETG and TPU, among other materials, allowing to print common, transparent and flexible materials with a wide range of hardnesses. Currently, Forward AM by BASF and Leitat are working to increase the supply of materials that can be used in this equipment. Meanwhile, access to this technology by the technical team of the IAM 3D HUB makes it possible to offer this production solution in its range of options for the development of new applications and for benchmarking activities.

Regarding FFF technology, Forward AM by BASF has also provided a BCN3D Epsilon printer. The new BCN3D equipment is a double extruder printer capable of manufacturing a wide range of materials that require high process temperatures such as ABS, PP, PPGF, PAHT, PETCF, allowing it to have the ability to manufacture high-rigidity, high-performance parts. mechanical or resistance to fatigue, as well as conventional polymers. The equipment allows reaching high extrusion temperatures and having a controlled working chamber temperature, allowing greater construction reliability with multiple high-performance engineering materials. It is also worth highlighting the efficiency of the equipment by being able to print simultaneously with both extruders, which allows reducing construction time in the manufacture of sets of equal or symmetrical pieces.

Regarding Photocentric equipment that works with photopolymerizable resins, they operate with DLP-LCD technology (Day-Light Photopolymerization by Liquid Crystal Display), which uses a visible light source to photopolymerize the pieces layer by layer, maintaining manufacturing times regardless of the amount of material to be consolidated in each one of them. This system offers a great competitive advantage since it allows to use of conventional screens instead of ultraviolet light systems and thus obtain a higher manufacturing volume, with high speed and productivity at a very competitive price, as well as a level of precision, detail and exceptional finishes. BASF has been developing its EPD range of photocurable resins compatible with Photocentric equipment, among which there are materials with high impact resistance such as EPD1006 or PED4006, and high rigidity such as EPD 3500.

These units are not only used for the study, development and market introduction of new BASF materials for the aforementioned technologies but also allow the IAM 3D HUB and Leitat to develop new advanced applications and industrial solutions for companies and sectors of the productive ecosystem with the aim of making them more competitive and accompanying them in the adoption of additive manufacturing.

It is expected to strengthen the ties between BASF, Leitat and the IAM 3D HUB with future collaborations to provide better solutions to the industry, help companies adopt additive manufacturing and improve the competitiveness of the industrial fabric of our environment.
