DSM Somos provided Somos 10120 WaterClear to produce 10 prototyped sets of the Pocket Spider IIc wireless modem for PDAs for use in a recent trade show.
The Pocket Spider, designed by RP Innovations of Richardson, Texas for OEM Enfora of Plano, Texas, is a small, compact wireless modem for PDAs.
The Pocket Spider is an enhanced generation of the first wireless IP (CDPD) modem designed exclusively for a CompactFlash slot.
Wireless IP supports browser-based applications for PocketPC and Palm devices providing mobile professionals enterprise access, the ability to receive stock quotes, send and receive e-mail, and get directions, traffic conditions and airline information.
In this prototyping application, the use of Somos 10120 WaterClear via stereolithography (SL) provided significant benefits.
For example, SL parts cost only $250.00 per set versus $595.00 per set for CNC aluminium prototyping.
Moreover, SL required only 3-5 days turnaround versus 12-15 days for CNC.
DSM Somos 10120 WaterClear, the prototyping material of choice, is a new stereolithography resin providing the optical clarity of many polycarbonates.
10120 WaterClear is a unique composite of many desirable engineering properties mimicking the flexural strength and modulus of polycarbonate, the notched izod impact strength of Nylon 66, and the tensile strength of ABS.
Its transparent appearance may be dyed, in a secondary step, for colour tint.
In addition to delivering optical-clarity, 10120 WaterClear prototypes ensure exceptional durability, toughness, and impact strength for testing of fit and function.
10120 WaterClear is part of the ProtoFunctional Materials family pioneered by DSM Somos.
ProtoFunctional rapid prototyping resins replicate the performance parameters of production materials - from thermoplastic elastomers to polyethylene and polypropylene - saving both time and money in new product development.
From a commercial production standpoint, the Pocket Spider, injection moulded by Phillips Plastics, maintains extremely tight tolerances coupled with the functional and aesthetic ergonomic demands of handheld PDA's.
Cycoloy, a high impact amorphous polycarbonate and acrylonitrile-butadiene-styrene terpolymer resin blend was selected for both impact strength but also to achieve a metallic appearance.
The Pocket Spider IIc wireless modem for PDAs is 98mm long without antenna (126mm with); 55mm wide, 26mm thick, and 57g in weight without its 99g battery.
