We coordinate all production steps for you and provide you with the complete assemblies. In the field of multi-component processing, we have for you determines an optimal solution. We can you make with the new process parts which due to insufficient wall thickness or flow paths, not, or only partially possible in vacuum casting.

MARAZZI OFF MECC deals with Turning, Thread Rolling and 3D Printing

With more than 25 years of experience in 3D printing, Materialise stands for expertise especially in the area of software for additive manufacturing and 3D printing services. The combination of our software solutions and service offerings merge into a flexible and open platform for the entire 3D printing industry, which companies from a wide range of industries can rely on: healthcare, automotive, aviation and space travel, design and consumer goods The most important. Based on our platform, innovative 3D printing applications become reality and make the world a better and healthier place. With its headquarters in Belgium and offices around the world, Materialize is the largest group of software developers in the industry, and has one of the largest 3D manufacturing facilities in the world.

Our continuously developing small group consist of many technicians and engineers.
(Typically the number of the employees is 10 to 12 people.)

We are really fond of the professional challenges, but during our work we strive for simplicity and try to find the most effective solutions, preferably in a good mood.

When we design a new product we pay attention to the functionality but we also take care for the ergonomy and choose the appropriate material according to an esthetic implementation.

Our intent is to supply our customers with well usable and high quality products which at the same time have a competitive prices.

We are open-minded for new technologies what we have not tried yet.

We are able to transform the workable things into a day-to-day practice, this is demonstrated by the current image of our company.

We pursue a mutually beneficial partnerships with our customers and subcontractors.
We are aware of our abilities and opportunities and our industry position.
Not in headcount, but in technological advances and efficiency we often go far beyond the bigger competitors.

Precision Mechanics is historically our core business and still counts the higher number of dedicated operators and machineries. We produce complex milling and turning parts in unitary and small/medium quantities: single prototypes and pre-series lots, spare parts and special formats, experimental parts, dies and models.
Our distinctive feature is the capability to supply quality and accuracy by respecting compulsory deadlines in urgency, fundamental service for long-time partnerships with the automatic machine industry (packaging and medical) and machine tools.
Rigorously multi-pallet and interchangeable if necessary, our machining centers serve the urgent prototype in an optimal way.

Metal3D SA
Has been established in order to become a key player on the fast developing market of the 3D metal printing. Metal3D SA is a valuable partner for any company wishes to benefit from this innovative technology, by offering engineering and manufacturing services.
We are aware that obtaining a state-of-the-art technology doesn’t end with equipment delivery. In itself, equipment doesn’t generate new competences. The real challenge is to develop the skills and knowledge to fit this innovative process into the current market needs.
Not only to target in engineering, aiming on “how a metal part should be printed”, but to optimally combine 3D printing with the traditional manufacturing technologies to generate the maximum benefit.

Metal 3D Printing Equipment
We had carefully analyzed the currently available technologies in this field and we had chosen to invest in this very first step in the Studio System+ from Desktop Metal Inc. and the Bound Metal Deposition (BMD®) technology.
BMD is the newest, but also the most mature technology in this field. BMD substantially relies on MIM (Metal Injection Molding), a mature and proven production technology for metal parts.
MIM produces metal components in three steps. Initially a mixture of metal powder with a thermoplastic binder is injected in a mold in a process similar to injection molding. From this stage we get the so called “green body” of the part. In a subsequent step, the binder is removed from the “green body”, leading to a brittle part known as “brown body”. Finally the “brown body” is sintered and the final sound metal part is produced.
BMD follows also these three stages with only a major difference on the first stage. The “green body”, instead of being molded, it is built by a 3D printer, which is similar to the FDM plastic 3D printers. Raw material has not the form of filament, but of rods made of a thermoplastic binder with a high concentration of metal.

Metal3D SA Services
We provide a complete range of services in the field of custom metal 3d printing.
To do so, we assist our customers in the first and most important question: “Will it be of any benefit to 3D print a metal part compared to the traditional manufacturing operations?”
In detail, we offer:
1. 3D printing of metal components as a service, including engineering consultancy for the adaptation of the part design on the specific requirements of this new production method
2. A wide range of post printing operations, i.e. high precision CNC machining, surface treatments, thermal treatments etc.
3. Metal 3D printing of cavity inserts for the construction of low volume injection molds and production of the plastic moldings.
4. Functional assemblies comprised by metal (3D printed or/and machined) components, plastics (molded or 3D printed) and standard items.

3D Printing Metals
We currently have experience with two materials:
• 17-4PH (EN 1.4542). A versatile stainless steel featuring substantial mechanical properties (ultimate tensile strength 1042MPa) and hardness (HRC 37). 17-4PH can be furthermore hardened (up to 48HRC) and also plasma nitriding.
17-4PH meets a 98% density after sintering
• 316L. Characterized by its corrosion resistance and performance at both high and low temperatures, 316L is a fully austenitic stainless steel. It is used often in applications involving chemical processing, salt water environments, and household or industrial fixtures.
Before the end of 2019 we will start using also H13, as soon as it is released from Desktop Metal. H13 is a chromium hot-work steel, which is widely used in hot and cold work tooling applications. Due to its excellent combination of high toughness and fatigue resistance. H13 is used more than any other tool steel in tooling applications.
Desktop Metal plans to release also the following materials: Alloy 625, AISI 4140, and Copper.
