New resin improves stereolithography
3D Systems Europe Limited has launched a new material, Cibatool SL7540, designed to create parts that mimic end-use plastics in stereolithography (SLA) applications
3D Systems Europe Limited has launched a new material, Cibatool SL7540, designed to create parts that mimic end-use plastics in stereolithography (SLA) applications, ranging from snap-fit testing to the creation of multi-component assemblies The cost effective resin can be used with 3D Systems' SLA 3500, 5000 and 7000 systems and enables users to move quickly from three dimensional designs to high quality, functional finished parts

Purchases double rapid prototyping capacity
The Viper Pro SLA System manufactures parts with exceptional feature details, accuracy, surface finish and large part size that are ordinarily associated with CNC machining.
Developed jointly with Ciba Speciality Chemicals under a partnership agreement, SL7540 has been formulated to provide durability and accuracy, even when worked at the high speeds of 3D Systems' popular SLA 3500, 5000 and 7000 systems.
The resulting resin exhibits mechanical properties similar to those offered by popular thermoplastics, such as polypropylene, polystyrene or polyethylene.
For example, parts created using the resin have the flexibility to withstand the rigors of functional testing and, in the majority of cases, the need for interim steps such as bridge tooling can be eliminated when using SL7540.
In addition, the resilience of the material means that models can be drilled, threaded, machined and polished, allowing users to test and demonstrate a fully functioning part.
The durability of SL7540 also makes it suitable for mould making applications.
Master patterns built using the new resin are capable of producing multiple moulds, even for demanding projects involving complex patterns, thin part walls, or elevated process temperature.
Consequently, prototypes can be tested rigorously while maintaining the integrity of the part geometry.
SL7540 is suitable for use in a wide range of automotive, engineering and electronics applications, and has already been used with great success in a series of projects in the United States.
For example, a squirrel cage fan constructed by a large automotive manufacturer both withstood 120C humidity testing and has been found to exhibit excellent balance during operation.
