Oh Oh Andrea




UV LCD from Zortrax Inkspire

Oh Oh Andrea has started manufacturing some of her jewelry and handcrafted jewelry pieces through 3D printing. This has allowed them to reduce manufacturing times in pieces that are very difficult to make by hand, due to their complex shapes, without neglecting the essence of their artisan jewels and with unique designs. Additive manufacturing has brought them great benefits, since they save time and production costs, offering the highest quality to their customers, which is why it becomes a new success story for INTECH3D in the jewelry sector.

About Oh Oh Andrea

Oh Oh Andrea is a company dedicated to the manufacture of handmade and exclusive jewelry, with an exclusive design, made with great precision in each of its details. They put care and a lot of professionalism into the elaboration of each jewel, with very original and different designs, making each piece of jewelery that leaves their workshop a unique creation.

Andrea Navarro, CEO and founder of Oh Oh Andrea, has always sought innovation by testing different materials and styles of jewelry. On this occasion, she has had the help of INTECH3D, who has advised her with the best 3D technology in her case and the optimal materials to develop her jewelry creation process.

For this reason, they have taken the step of using 3D printing for jewelry due to the benefits that it can provide in the manufacture and validation of their designs.

3D printing reduces production costs in jewelry manufacturing by 85%

“3D printing has marked a before and after in our company. We have reduced costs by 85%, without having to outsource the prototypes and carrying out a much cheaper trial-error process. Of course, we have also greatly reduced manufacturing times, and in relation, the time to market, since previously the prototypes could take up to two weeks and now we can get the parts in 3D in one night. Another important aspect is that the Zortrax Inkspire printer allows us to work with different resins, some more basic and cheaper, which we use for testing, and others of the highest quality to manufacture the final parts.”

The challenge: reduce manufacturing times without abandoning crafts

One of the main requirements of Oh Oh Andrea consisted of not neglecting the handmade and unique manufacture of each piece, the essence of its brand, but at the same time getting more pieces in less time, as well as reducing the manufacturing times of its products. prototypes. They were also motivated by the reduction in costs that they would obtain, being able to offer excellent quality as up to now, with shorter time frames, also achieving the satisfaction of their customers by having their jewelry sooner.

Oh Oh Andrea wanted to find a technology that would allow her, on the one hand, to prototype and on the other, to continue working with the lost wax process. Additive manufacturing fully meets this requirement, since it allows them to work with different resins, some more basic and cheaper, which they use for testing, and others of the highest quality to manufacture the final parts for the casting process.

3D printing has opened up a world of possibilities for them in terms of design, since they can create shapes that are very difficult and even impossible to create by hand. From Oh Oh Andrea they needed to work with a technology that will not generate waste during the casting process, to achieve the jewels with the ideal design.

The solution: 3D printing to make tests cheaper and create final pieces of jewelry

The integration of additive manufacturing has provided great benefits to Oh Oh Andrea in its two essential processes in jewelry manufacturing.

In the prototyping process, it has allowed them to reduce manufacturing risk and the times and costs associated with it. One of the great advantages, with which they have found, is the possibility of showing the designs to the clients before their manufacture, thus achieving that these pieces of jewelery are of their maximum satisfaction.

The additive manufacturing technology that has been implemented in Oh Oh Andrea is the Zortrax Inkspire UV LCD. This technology enables them to manufacture components with a great level of detail, avoiding the appearance of bubbles in the casting work.

With the incorporation of this 3D technology, they have begun to work with 100% burn-out resin that helps them improve the creation process. During casting, the printed parts perform optimally and no waste is generated.

Project results: reduction of prototyping and manufacturing times and costs

One of the most significant improvements that they have experienced since Oh Oh Andrea, thanks to incorporating additive manufacturing in their jewelry workshop, is that they have gone from investing two weeks with the previous process to taking twelve hours to manufacture a piece.

On the other hand, they have reduced production costs by 85% without having to outsource the prototypes and being able to control the entire procedure with a much cheaper trial-error process than the previous one.

“Oh Oh Andrea is committed to innovation without losing its artisan character”

Currently, Oh Oh Andrea has a 3D printer for the creation of pieces of jewelry of its own design, using resin as a material for 3D printing.

Thus, while the design that has been previously sent is being printed, at Oh Oh Andrea they can spend that time performing other tasks. Thanks to this new manufacturing process, they achieve unique jewelry in a faster, more efficient and cheaper way, which would require a much more laborious process manually.

Oh Oh Andrea now can make and sell their designs with an added value to the previous one, betting on craftsmanship with a touch of innovation, which confirms that 3D printing is not mutually exclusive and complements perfectly with the more traditional manufacturing processes.
