SLS helps produce the tennis racket of champions

SLS is used in design of tennis rackets.

SLS ensures optimal performance for new sporting equipment designs.

The tennis racket manufacturer of choice, for tennis stars such as Nikolay Davydenko, Juan Carlos Ferrero and Jelena Jankovic, Prince Sports has enlisted the help of SLS technology to ensure the optimal performance of their range of tennis rackets.

Working closely with a local rapid prototyping bureau, Prince sports required the manufacture of inserts/outer clips surrounding the racket perimeter and an  initial prototype 1:1 scale aesthetic model of a prototype tennis racket, which if the inserts/outer clips SLS manufacture proved successful would be the first in a series of 30 rackets inspired by this technology.

While initial testing of the inserts and outer clips unfortunately resulted in the insert giving way, th

ese early tests allowed for the initial design to be upgraded to enhance the performance durability of the overall insert design. For Prince Sports these early testings of the inserts are crucial to the performance of the overall piece, as loss of energy due to insert deformation will impact on the speed of the ball, a key consideration for tennis players competing against some of the worlds best players.

Once satisfied with the insert design a 1:1 scale model of the racket frame and bumper was produced, with all three parts assembled upon completion. For Prince Sports the prototype racket assisted in the further development of the aesthetics and functional of the overall design.

Can 3D printing help save burns victims?

3d printing of human skin

Researchers aim to save lives with 3d printing of human skin

Researchers at the Wake Forest Institute for Regenerative Medicine are working to unlock the healing benefits of 3d printing, with the aim of helping wounded soldiers.

The team have redeveloped a standard store bought 3d inkjet printer, to facilitate the printing of living cells as ink. Other modifications to this technology include the development of a 3D “elevator” and pressurized nozzles to allow a safe distance to be maintained between the printer and the patient.

Initial testing on mice has revealed an advanced rate of healing by the second and third week in comparison with the rate of healing in untreated subjects. A combination of skin cells, coagulants and collagen are printed directly onto the wounded tissue which are then topped by a layer of keratinocytes (i.e. skin cells) – also printed. On application to the wounded tissue the cells would mature to form new skin.

Future trials will be conducted on pigs, whose skin structure more closely resembles that of humans. While in reality 3d printing of human skin may yet be a long way off the promise of this technology is truly incredible. Research has shown that the longer it takes to cover a wound with skin, the higher the risk of infection, complications and death, should this technology reach local and field hospitals it is likely to have a significant impact on the survival rates of burns victims.

Shoemaker grows business with 3D Printing

The UK based, global shoe manufacturer Clarks has transformed its product development process with the aid of 3D printing technology.

Clarks 3D Printed Shoes
3D printed prototypes reduce product development lead times and costs for Clarks


Breaking away from the traditional approach to shoe design, Clarks has introduced 3D printing to their design process, leading to considerable savings in both development costs and lead times. The traditional approach begins with hand sketches on paper, which are reviewed and revised several times over until a product concept is approved. The upper materials are then sourced and the concept sent to a shoe factory, and then you wait for several weeks for the sample show to arrive. The sample is then reviewed and original sketches once again revised and modified prototypes ordered until the final product design is reached.

For Clarks this lengthy and often costly design process has been thoroughly modernised with the help of 3d printing technology. After the initial paper sketch, designs are moved to 3D CAD software where designs can be manipulated with minimal effort until product managers are happy with the on-screen concept. And then with the simple push of a button a prototype shoe can be quickly printed in the design office, shrinking the design process significantly.

For Clarks digital development manager Ross Arthurs 3D printing has allowed Clarks to “respond to the market faster than ever” and “to evolve from the best shoemakers in the world into the best innovators in the world” (TCT Magazine 04/11).

3D Printing Science or Art?

A while back I came across an interesting project called SculptCAD Rapid Artists, which left me wondering if 3D printing is really science or merely an extension of traditional art techniques.

The SculptCAD Rapid Artists project invited 12 artists to diverge from their regular mediums to create something new using state of the art digitalising tools.

The result a contemporary approach to art, which produces high speed and on demand pieces, and allows even impossible geometries to become possible. Each artist interpreting the possibilities presented by 3D tools and prototyping to create sculptures representing their personal creative outlook.

When asked about his experience Brad Ford Smith revealed that one of his greatest surprises during the project lay not in the impact of using 3D tools, which as he expected “did not make the creative process any easier”, rather in the response of people to the project. While many welcome this technology’s use for the replacement of missing or damaged bones its application to the world of art was met with long discussions on the value and nature of art, and acted as further proof that art will be fabricated by the simple push of a button, and that our culture is going down the tubes.

Selective Laser Sintering takes flight

Scientists at FESTO have unlocked the secrets to the swooping movement of birds in flight.

A revolutionary feat of engineering, the SmartBird design allows it to not only fly but also start and land autonomously – without the help of any additional drive systems-. Inspired by the herring seagull, and boasting
2 meter long wings the SmartBird when left to its own devices can simply glide through the skies or can be controlled through a radio handset.

The robot’s wings can not only beat up and down but also twist at specific angles along their length in the very same way that a real bird’s do. Directional control is achieved through the opposing movement of the Smartbirds head and torso sections which allow for aerodynamic movement and simultaneous weight displacement, while the tail produces lift functions.

Smartbird: Excellent Aerodynic Qualities and Extreme Agility
Realistic: The SmartBird’s wings not only beat up and down, they also twist at specific angles

Packed inside the SmartBird’s torso are the battery, engine and transmission, crank transmission and control and regulation electronics. In order to ensure the SmartBird could float through the air with moderate flapping, it was necessary to ensure minimal use of materials and the lightweight construction, this was achieved through the SLS process which allowed for a functional housing to be constructed at minimal weight – the SmartBird weighs a maximum of 450 grams

So realistic are the movements of the Smartbird that from the ground it would be easy to mistake it for the real thing.

We at Laser Prototypes are excited to see where Rapid Prototyping will show up next!

It appears that the gap between Rapid Prototyping and final production is shrinking even further, as EOS introduces the latest addition to their range of DMLS machines.The worlds largest SLS machine manufacturer hasunveiled the latest in the evolution of their DMLS systems. The latest addition to the product range sees the conversion of the DMLS system into full-fledged production tools for economical, batch-size, optimized manufacture of parts at all stages from prototyping through to finished product. 

The M280 builds on the capabilities of the EOSINT M270 (currently the leading system on the market for additive layer manufacturing of metal components) and can build fully functional parts in a wide range of materials, with standardisation and quality assurance capabilities on a par with those of traditional manufacturing processes.

We wonder if mass customisation of end products is even closer at hand than we had originally thought.
