vieira4Little by little, we enter the fascinating world of parametric CAD. At first, we molded openwork vessels, for the mere pleasure of experimenting, without claiming any use. We started out playing as silver potters. Later, we have oriented our parametric CAD games towards jewelry, exploring its potential. Discover them in this video.

vieira4The pilgrims of Santiago de Compostela usually wear a scallop shell in order to symbolise their pilgrimage to the site where the apostle's remains are kept. The pilgrim's scallop acquires a spiritual significance. Several legends are told about their origin as a lucky charm during the pilgrimage. I will only state what I like the most, and which is more inspirational in this design: the undulations of the shell stand for a radial convergence of trails aiming at the same meeting point, from several different points of departure. In this case we have designed a silver scallop digitally which, however, will have to be manufactured by means of traditional techniques, why?

By mirror we mean a flat mirror-polished surface. Apparently, this design suffers from the same aversion. A pair of burnished yellow and white gold earrings (total of 29 grams), with 30 brilliants (total 1.55 kt), 2 rubies of 5.0 mm (approximate total 1.0 kt) and enamels.

Here is a new example of the valuable contributions of the digital technique applied to jewel modelling, particularly with geometrical accuracy of the 3D modelling software to enhance the beauty of the designs.

It was applied to the modelling of a pair of burnished yellow and white gold earrings (total of 29.5 grams), with 1.44 kt of brilliants, 4 pearls of 4mm, 2 pearls of 3.4mm and enamels.

This work illustrates the best techniques and aesthetic features provided by 3D digital modelling compared to traditional techniques. It also shows the optimization of working hours by saving time for the goldsmith and the gem-setter.

New technologies allow the customer to supervise the work of the artisan through Internet. The models are manufactured in stages, and we do not proceed from one to the next without prior approval by the customer. The modelling in supervised stages minimises the costs, flaws and makes it easier to introduce corrections, and improve the customer satisfaction with the finished work.

Modelling in 3D without having previous knowledge as a goldsmith would be like proceeding blindly with the modelling. The restriction of what can not be done or which could be highly expensive is defined by the following processes: casting, hand grinding and burnishing.

3D modelling and printing by means of software complement the traditional goldsmith techniques but do not substitute them. The models printed in plastic or resin, are then melted in metal and are finally ground and burnished mechanically or by hand.
