K3D finalist Design for Additive Manufacturing challenge 2019


Winners 2019

During the awards dinner of the 7 th edition of the Additive World Conference, Chairman of the Jury, Ultimaker's Steven van de Staak, announced K3D and Obasogie Okpamen as winners of the Additive World Design for Additive Manufacturing Challenge 2019. All finalists, three in the student category and three professionals, pitched their designs in front of the 5-member jury.

The winner of the professional category is K3D of The Netherlands. K3D CTO, Jaap Bulsink, presented the dough cutting knife they developed for bakery equipment world leader and mother company, Kaak Group. This real life product and case study combines an amazing number of advantages 3D metal printing offers, like weight reduction, part count reduction, porous structures, integrated channels, increased performance and substantial cost reduction with a very practical and original application. The business case is very strong, especially because of the weight saving that results in higher moving speeds of the knives which allows for the saving of 2 out of 8 robots in a production line. What makes this case study even more impressive is the integration of mechanical parts, a spring leaf and bearing and the fact that it is completely designed for AM. The K3D team designed a part that can be printed without any support structure, even threads of the interface with the robot are printed and can be used without post-machining. Finally, the porous knife blade, created by an inventive and custom parameter set, improves the functionality substantially by creating an air shield around the blade.

In the student category the first prize went to Obasogie Okpamen from The Landmark University in Nigeria. He redesigned a connection rod for an Alfa Romeo 75 Twin Spark Turbo engine. Although the design was not completely tested yet, the Jury appointed him winner because of the example it sets. Huge amounts of used cars that are written off in Europe, are shipped to Africa to have a second life. This results in a high demand of spare parts to sustain this life. This relatively simple application shows a huge potential in the spare parts market. Additive Manufacturing allows for distributed localized manufacturing of spare parts in many more categories than the automotive after-market.


On Thursday, February 7, 2019, Additive Industries announced the finalists of Additive World Design for Additive Manufacturing Challenge 2019. From a group of 121 contestants, both professionals and students, 3 finalists were selected per category.

The designs are (from left to right, first top row then bottom):

“Hyper-performance suspension upright” from Revannth Narmatha Murugesan, Carbon Performance Limited (United Kingdom, professional category)
“Cutting dough knife” from Jaap Bulsink, K3D (The Netherlands, professional category)
“Cryogenic Cold Trap” from Kartheek Raghu, Wipro3D (India, professional category)
“Brake Caliper” from Nanyang Technological University team (Singapore, student category)
“Cubesat Propellant Tank” from Abraham Mathew, the McMaster University (Canada, student category)
“Twin Spark Connecting Rod” from Obasogie Okpamen, the Landmark University (Nigeria, student category)

Additive Industries wants to challenge both professional designers and students

In order to raise the number of examples and inspire many other industries to develop dedicated applications for industrial 3D printing, Additive Industries has launched the 5th edition of the Additive World Design for Additive Manufacturing Challenge. Competing in two categories both professional designers & engineers and students are encouraged to take an existing part of a machine or product that is made with conventional technologies today and redesign it for 3D printing. Partners in the Design for Additive Manufacturing Challenge are leading CAE technology provider (eg Topology Optimization) – Altair Engineering, a consumer 3D printer manufacturer – Ultimaker, Autodesk – a leader in 3D design, engineering and entertainment software and European Association of the Machine Tool Industries CECIMO.

The top 3 in both categories get a free 1 year license of Altair's Inspire software, netfabb and a Fusion360 License from Autodesk. All finalists are invited to join the Additive World Conference and Additive World Awards Dinner at no cost.

The winners in both categories take home the Ultimaker 3D printer (professional winner Ultimaker 3 and student winner Ultimaker 2+) and a larger package netfabb and Fusion360 License from Autodesk. Also the award winning designs will be printed in metal.

In order to assist the participants in the Additive World Design for Additive Manufacturing Challenge to make the best design possible, Additive Industries is offering help. During the Additive Industries Support Sessions in January 2019, participants can contact the Additive Industries by telephone or webmeeting for support in topology optimization (with Altair solidThinking Inspire) or to evaluate the printablilty. We have the following possibilities for this (limited) topology optimization assiastance, please book a timeslot through m.engels@additiveindustries.com:

Registration for Design Challenge 2020 is possible via this website from October 23, 2019† After the registration you will receive an Additive World Design for Additive Manufacturing Challenge Manual with the requirements & rules and important deadlines for sending your design. The (re)designs, together with the Submission Form and the motivation should be sent until February 1, 2020† For questions please contact our team: design challenge@additiveindustries.com or by phone +31 (0) 40 2180660.
