Facilitating Rapid Product Development With Rapid Prototyping
Back in 2003, some would say light years ago in terms of how quick technology is evolving, WelTec Connect, then known as Rapid Prototyping New Zealand, first started rapid prototyping using a Z Corp 3D printer.
In view of the fact that then, the experts at WelTec have developed a range of services dedicated to decreasing the time required to yield prototypes.
- Fused deposition modelling (FDM) – a 3D printing technology (which is a form of preservative manufacturing) that takes virtual designs from computer aided design (CAD) or animation modelling software, transforms them into thin, virtual, horizontal cross-sections, and then makes successive layers using near-molten plastic (ABS) or polycarbonate until the model is complete.
- Four-axes computer numerically controlled CNC machining – cutting away at a levelheaded block of material to start a final model. The material used in CNC prototyping can range from soft materials like foam and plastic to hardened steel. It’s an effective method for functional testing of prototypes when actual materials that will be used for eventual mass production are utilised during the machining.
- Vacuum Casting – High density waxes, silicon moulds and polyurethane parts are produced using a method called vacuum casting. A prototype made from a silicon mould will mimic the final product close enough for function testing and test marketing purposes.
- Vacuum forming – a sheet of plastic is heated to a forming temperature and stretched onto or over a mould and held there by applying a vacuum between the surfaces.
- Laser cutting and etching
The Centre for Smart Product also carries out production and testing of prototype circuit boards, pre-production runs of products, and performance testing.
According to, Paul Mather, the Director of Technology Development for the Centre, rapid prototyping can effectively reduce the amount of time needed for development and testing of a new product. This accelerates the process between design and production and allows companies to get their products to market quicker. This kind of efficiency can make any business more competitive its industry. In an arena where being first to market counts, this can have a profound effect on profits.
A diverse range of individuals and businesses access the Centre for Smart Products rapid prototyping gear and services, and WelTec Connect can work with people in a range of ways from the initial design concept through to just carrying out the product prototyping.
Paul Mather says, “It is up to the individual or company involved as to how much input WelTec Connect has on the project. We can work at developing design thoughts and making prototypes from the concept the boards plus full testing of these products, but we are also able to just build prototypes from SDL files sent to us.”
Staff members and students who teach and study at WelTec’s Schools of Creative Technologies, IT and Engineering are available to lend knowledge and expertise to any project at the client’s request. These resources have proven to be invaluable to the development and testing of prototypes for many new products. The strong emphasis on engineering is particularly attractive to companies involved in manufacturing.
The rapid prototyping technologies at WelTec Connect are available on a user pays footing but could possibly be part of a Research and Development funding package too. Talk to Paul Mather at WelTec Connect for more information.
