A new thermoplastic-like stereolithography (SL) photopolymer, RenShape SL 5260 and range of SL adhesives – RenShape SL Bond – have been launched by RenShape Solutions, part of Huntsman Advanced Materials.

RenShape SL 5260 is formulated for use on SLA 250 He-Cd platforms and is said to produce durable, opaque white prototypes and parts with an ABS thermoplastic-like surface, It claims a rigid flexural modulus of 2,400 MPa and an elongation of 12 per cent together with good accuracy and fast processing speed.

According to RenShape this new material, along with ABS-like RenShape SL 7560 and the clear SI 7565 photopolymers formulated for use on SLA 7000 platforms, enables customers to broaden their capabilities for the production of stereolithography-generated parts. For example, service bureaux can use SL materials rather than conventional polyurethanes cast in RTV silicone rubber moulds to produce accurate and durable functional prototypes that simulate the performance of engineering thermoplastics, They can also be used to make highly specialised short run production parts such as custom moulded hearing aid shells.

In addition to this new SL material, RenShape Solutions is launching a range of adhesives specially designed for filling and bonding SL models and prototypes.

RenShape SL Bond 110 has an easy-to-apply low viscosity level; SL Bond 120 is a standard- viscosity material while SL Bond 130 is thixotropic for good sag resistance on vertical surfaces.

All SL Bond adhesives are packed in convenient 10 ml syringes for easy, waste-free dispensing.

RenShape also reports the launch of a new modelling paste.

RenPaste SV/HV 4503-1 is a new version of the already established material SV/HV 4503 widely used for model making. The new version claims two main advantages – a finer, smoother surface to reduce surface finishing operations and fewer heat build-up during curing to reduce stresses in the model structure.

SV/HV 4503-1 is said to retain all the other application characteristics claimed of SV/HV 4503 – fast application of void free layers of up to 40 mm by specially designed equipment, and milling characteristics that enable fast cutting combined with very low abrasion of the cutting tool.
