Ultimaker 3

The Ultimaker 3 is an entry level system used to support coursework at the University of Michigan. The Ultimaker 3’s features are tightly integrated with Cura, a popular open source slicer application, offering user centric features such as a front facing USB port, a simple user interface, and auto-bed leveling. Those who are a bit more experienced can take advantage of the printer’s dual heads for 2 color printing or to create more advanced geometries with water soluble support structure. The Ultimaker 3 is a perfect solution for class support and is available by faculty, instructor, or student advisor reservation only.

Understanding the Technology

What is FFF: In a process known as Fused Filament Fabrication (FFF), a.k.a. Fused Deposition Modeling (FDM), the Ultimaker 3 additively builds objects by selectively applying a heated thermoplastic polymer in layers, typically 100 micron thick, from the build tray to the top of the part. 

FFF Materials: Ultimaker 3D printers in the Fabrication Studio use PLA plastic for model material and PVA (polyvinyl alcohol) a water soluble support material. PLA is a biodegradable plastic that is made from renewable resources like cornstarch or sugarcane. When compared to ABS, PLA is not quite as strong but the material uses less energy to form; is less likely to warp; is safer to use; and has less of an impact on the environment, making it an ideal material for 3D prototyping.

FFF Benefits: FFF 3D printers, such as the Ultimaker 3, provide an easy to use, cost effective solution to additive manufacturing. Due to their relative simplicity, FFF 3D printers tend to be inexpensive. FFF printers are highly tunable allowing users to adjust model infill and layer resolution which can reduce print time and cost. Low cost hardware, flexibility, and a wide selection of materials make the FFF the most common choice for 3D printing.

FFF Disadvantages: Because objects are built up from a thin bead of material, typically measuring 0.4 mm in diameter, build times are measured in hours to days. The filament extrusion process also limits feature detail, provides low dimensional accuracy, poor surface quality and part weakness between the layers in the z axis. Support structure is required for overhanging geometries which must be removed and negatively impact surface quality.

The history of Ottobock

The history of Ottobock

The history of the development of the family business

The beginning of the journey

1919 – Orthopedische Industrie GmbH

Otto Bock wants to use serial production of components for the improvement of prosthetic and orthopedic veterans in ten thousand orthopedic patients. Together with like-minded people, he founds the Orthopaedische Industrie GmbH in February 1919 in Berlin. In the autumn of the same year, the company moves to Königssee (Thuringia) due to political unrest in the capital.

1923 - Königssee becomes a scientific center for the production of leg prostheses

In cooperation with medical specialists, Otto Bock develops a scientifically based method of "assembling a prosthesis with a plumb line", which he shares with technicians and doctors.

1935 – Max Näder sets the course for his career at Ottobock

Max Näder (1915-2009) completes his apprenticeship as an orthopedic technician and production assistant at Ottobock right after graduation. At 1943, he marries the youngest daughter of Otto Bokk - Maria.

Duderstadt

1946 - Max Näder opens his business in Duderstadt

Starting from scratch, Max and Maria Näder open a "northern branch" in Duderstadt. They supply the raw materials in Königssee and receive the finished product back. This makes them the first to introduce interstate trading in Lower Saxony.

1949 - the first resounding success of the company - the Jüpa knee module

The Jüpa knee joint with a brake mechanism, providing a high level of stability in the standing position, was a breakthrough in technology for adapting the user to the use of a prosthesis at the initial stage of a step.

1953 Addition of synthetic materials to production

Wood becomes a scarce raw material and Max Näder, experimenting with polyurethane foam, discovers synthetic components for the prosthetic and orthopedic industry. Founded in 1953, Otto Bock Kunststoff GmbH also offers products for the automotive and furniture industries.

Globalization of the company

1958 - the beginning of the globalization of the company begins with the opening of a representative office in the USA

Max Näder ensures the company's survival during the Cold War by opening Ottobock's first branch in Minneapolis. Subsequently, new branches are opened, one of which in Vienna in 1968, which has become an important location for research and development.

1961 - opening ceremony of a new warehouse complex

In the year of the birth of his son Hans-Georg, Max Näder acquires a piece of land on the Industriestraße in Duderstadt, which is planned to be used for foam production buildings (1963) and orthopedics (1965).

New standards

1965 - Max Näder introduces the myoelectric prosthetic hand

Each muscle contraction with the help of electrodes is converted into control signals for the prosthesis. For the first time, it is possible to grab light and breakable objects, as well as objects weighing several kilograms.

1969 - global standard - modular prosthetic construction system

The development of the Ottobock component system for building a modular leg prosthesis continues. Patented at 19The 69 alignment pyramid connects the foot, knee module and prosthetic socket, allowing static adjustment and replacement of modules.

1987 Tubingen hip abduction orthosis for children

Orthoses are used to support parts of the body with limited functionality, as opposed to prostheses that completely replace limbs. Since 1987, the Tubingen hip abduction orthosis has been the standard treatment for dysplasia in young children.

The Paralympic Movement

1988 technical support for athletes at the Paralympic Games

Four technicians from Ottobock Australia provide repairs to prosthetics, orthoses and wheelchairs during the Seoul Paralympic Games. Since then, Ottobock has provided technical support to athletes at all Summer and Winter Paralympic Games.

In 2005 Ottobock became a Worldwide Partner of the International Paralympic Committee.

New era

1990 Hans-Georg Näder becomes CEO of

Like his grandfather and father before him, Hans-Georg is following a path of using innovative technologies to improve the mobility of people with disabilities. He continues the further globalization of the company and makes it a world leader in technical orthopedics.

1991 - The Näder family buys back the former headquarters in Königssee

After German reunification in 19In 1989, the family of entrepreneurs reestablishes contact with the former headquarters of the company, which since 1948 has functioned as a people's enterprise in the GDR. After lengthy negotiations, Hans-Georg Näder signs a buyout agreement in 1991 and restores the plant. The new manufacturing facility focuses on the production of wheelchairs.

Innovative products

1997 C-Leg breaks new ground in walking

Hans-Georg Näder notes the innovative potential of the Computerized (C) leg presented by Canadian Kelly James in Chicago at 1992 - and acquires a patent. After five years of development, he presents the C-Leg, the world's first microprocessor-controlled knee module, at the World Prosthetics Congress in Nuremberg.

2003 - 1010 - landmark developments in upper limb prosthetics

Introduced in 2003, the DynamicArm prosthetic hand provides functionality that is as close to natural as possible. The Michelangelo hand, developed in 2010, can perform seven types of grips based on signaling when the muscles in the hand contract.

2011 - the Genium knee module - a new milestone in prosthetics

The development of electronic knee modules - including also C-Leg 4, Kenevo and Genium X3 - and mechatronic feet, makes possible the maximum adaptation of prostheses to the needs of the user, regardless of his age and activity level.

Investments

2009 - Opening of the Science Technology Center in Berlin

The center is an exposition of the company's technical achievements since 2009for 2018. Created to inspire millions of people, it is a meeting place for industry experts and policy makers from around the world.

2010 - Ottobock revitalizes the Bötzow quarter in Prenzlauer Berg

Professor Hans-Georg Neder acquires a plot of over 23,000 sq.m. in the heart of Berlin. Based on the master plan of renowned architect Sir David Chipperfield, he develops the complex in a contemporary style. Places to live, work and create in close proximity to the laboratories of the future Ottobock on the Prenzlauer alley.

Development

2017 - strategic decisions open the way to the future

Swedish private equity firm EQT is acquiring a 20 percent stake in Otto Bock HealthCare, thereby supporting the company's ambitious growth goals in prosthetics, orthotics and rehabilitation. This deal makes it possible to acquire innovative technologies: the bebionic hand prosthesis and the Empower foot.

2018 - cutting-edge technical ideas for new challenges

The updated C-Brace, which uses innovative sensor technology to control the stance and swing phases of the entire walking cycle, is revolutionizing orthotics for paraplegics. As a result, the user's walking pattern is as close to natural as possible. The Paexo exoskeleton, the first product of Ottobock's new business line, provides relief to the spine during daily activities.

Future

Future - 3D printing technologies at the center of future projects

The expansion of the use of digital technologies, such as 3D printing and the use of artificial intelligence, allows the development of new lines of business. The main thing in the work on new projects, as well as the basis of all our activities, is the preservation or restoration of the mobility of people with limited mobility.

Additec launches μPrinter, a professional-grade desktop 3D printer. According to the developers, this is the most compact 3D printer in the world for direct metal laser 3D printing.

No, this time we are not talking about 3D printing with polymer filaments filled with metal powders, but about real printing with metals, using both wire and powder materials. The size of the construction area of ​​the Additec μPrinter 3D printer reaches 160x120x450 mm - not the highest figure, but this is the price of compactness and cost reduction. The developers conceived the device as a laboratory system and a relatively inexpensive entry-level 3D printer for companies interested in full-fledged additive manufacturing of metal products.

The main consumable is ordinary, inexpensive welding wire with a diameter of 0.6 to 1 mm, although metal powders can be sprayed using the same head. Fusion in the standard version is carried out by three diode lasers with a total power of 600 W, but if desired, five lasers can be installed and the power can be increased to 1 kW. Optional upgrades include up to two wire feed systems, each capable of handling four materials simultaneously, or up to four powder feed systems. Each of the emitters will be equipped with a laser designator in the visible range, which makes it easier to focus the beams at one point. To protect against oxidation, a sealed chamber with an inert gas supply is provided.

After applying each layer, the system resets the zero on the Z axis, measuring the distance from the top layer, and in case of failure, it cuts the wire itself, returns to the problem area and resumes the process. All this saves argon and reduces operator intervention to a minimum. Designers believe that such functionality will save a lot of time and nerves when working with experimental materials. An on-board camera is provided to monitor the 3D printing process.

“The Additec μPrinter is well suited for R&D. Its ability to handle both bars and powders allows it to handle a wide range of applications. All data from the integrated sensors, including the pressure in the material supply system, the temperature in the working chamber, the level of oxygen, and so on, can be displayed for monitoring and analysis through the auxiliary USB connection. Also, any parameter can be changed in G-code on the fly, and we provide a very capable utility that allows you to combine commands and data for testing and automation through a web interface. Finally, a fixed head and an optional transparent panel make it possible to integrate additional equipment for monitoring workflows,” the developers explain.

Additec μPrinter Desktop System is priced at $90,000 as standard. Additional information is available on the manufacturer's website at this link.
