In this production technology, the powder bed contains and supports the shapes and in this way it allows to easily create very wide and complex objects.
We do not produce standard 3D printers: we offer the market custom-designed machines, depending on the size and the specific sector in which they have to operate.
Our standard is technology, at the highest level currently developed.
The production process becomes faster, more fluid and more versatile. You can produce different objects, simultaneously; copies of the same object, or parts of it, even after some time; serial objects that differ only in small details.
All this without cost differences, with greater rapidity and a considerable reduction in the waste.
All our machines are designed according to CEI – EN standards and guarantee the highest quality and safety in all use phases.
The main operational operative features of Desamanera systems and printers meet practical and daily needs: ease of use, maximum reliability, simple and intuitive control and maintenance.
Own production system innovation determines important competitive advantages: it offers the opportunity to improve its own value proposition (services and products) and, consequently, to innovate the reference market and penetrate new sectors.
Additive Manufacturing was born more than 30 years ago as a rapid prototyping technology. Step by step it consolidated processes, technologies, models and paradigms.
AM is grown and consolidated as a customized-production technology and every day it opens up new revenue areas, sector by sector.
We have the fourth industrial revolution in front of us, and we are just getting started:
Every product goes through the prototyping phase, a product design key moment that highlights strengths and weaknesses. Thanks to the prototype the imagined object output is evaluated in concrete and allows all the necessary optimizations: production process and time, product performance and appearance, tests and market analysis, marketing activities and product launch out, both cost and revenue economic evaluations.
Thanks to its flexibility and cost-efficiency, Desamanera 3D printing is the ideal technology to produce prototypes in the most effective and fastest way and to produce many more, in particular for medium-large objects with ceramic, stone, marble, …
The 3D printing technology starts to be specifically optimized and adopted in mass production. It may seem a paradox, but it is not: it is the paradigm of mass customization, where production processes and technologies offer the mass production affordability and, at the same time, guarantee customization opportunities reserved, so far, to the customers of most high-end artisans and to the luxury market.
Industrial production 3D printing is already consolidated in some sectors, such as Dental, Automotive, Aeronautics and Space. With the aim of reducing costs and increasing efficiency, many other manufacturing industries are intensively investing to acquire a very important competitive advantage that widens the range of potentially achievable merchandise sectorscommodities sectors and markets and introduces innovation even in mature commodities sectors.
Universities and Research Centers, as well as internal corporate R&D departments, share the desire to discover, study, test and optimize new technologies and new materials.
The goal is to improve human well-being and quality of life, to the benefit of all. Even in ways that Desamanera haven’t thought yet:
When the need comes in one time, the absence of familiarity with the technology and the resources required can be overcome only with a professional 3D printing service and expert and competent assistance. The companies that offer 3D printing services are more and more numerousconstantly incresed, precisely because the demand for this service is always greater.
The catchment area expands much more, since there are no direct competitors as much effective in terms of time, shape, size and complexity; there are no competitors that serve selected mineral and environmentally friendly materials.
These reflections are the result of in-depth research and dialogues with professionals in many sectors. The technology, the processes and the materials we have developed, because of their relative youthlimited age, nowadays have found solid application only in a small percentage of the areas that can be potentially revolutionized.
The next one could be yours.
It creates objects from minerals powder: add material and minimize waste production.
This differs from subtractive production methods such as sculpture and CNC machines, which do not allow specific shape complexity and do produce a large amount of waste material.
Direct 3D printing (for example extrusion technology) freely deposits the material: supports are needed for particular shapes and overhang, a precise production speed must be respected according to the characteristics of the material used, the change of material during printing may be the cause of slowdowns and inefficiencies.
Indirect additive manufacturing, instead, uses a process that first distributes the material and after deposits selectively the binder to consolidate only a part, depending on shape and useful thicknesses.
The powder bed created contains and supports shapes and sizes of all kinds, with stability and without time constraints.
The traditional manufacturing methods of materials such as minerals, stone, marble, … are based on expensive and bulky equipment, resins and chemicals, molds, complex production processes.
Quite the opposite, Desamanera technology has been purposely designed for:
R&D is fundamental for us. We chose how to design every element of the system, from mechanics to electronics, from fluid dynamics to ICT, and we personally experience every production process phase.
Each component is subject to test and research and reaches cutting-edge performance also thanks to the collaboration with Universities and Research Centers and the participation in national and international projects. Among the many, we proudly mention the University of Padua, the German Federal Institute BAM, the ADMIN4D project and the H2020 RISE-AMITIE project.
Desamanera 3D printing technology is designed for inert materials use, in very fine particle size. The production consolidates the powder through a chemical reaction and the printed material appears as a stone.
For us, the environment respect is fundamental: the aggregates we use most are marbles, dolomites, stones, sands coming from the other processes waste; the binder is an our patented formulation which includes only natural inorganic materials and which can replace Portland cements use.
However, the technology allows the choice of other materials according to the chemical, physical and performance characteristics, required for specific uses.
Inert material with 0.5 – 2 mm particle size. It can be stones, marbles, sands, pure or mixed together, also coming from other processes waste.
The binder we developed in collaboration with the University of Padua is natural, inorganic, environmentally-friendly and composed by readily available raw materials.
It is patented, and according to our current knowledge it is the only one in the world activated exclusively by water.
Desamanera technologies also allow the use of other binders without particular design changes, depending on the production requirements.
Please consider alternatives to the Portland cement use, if possible: it is one of the major CO2 emissions cause in the atmosphere.
The technical characteristics and mechanical properties of the printed material change depending on the used aggregates and binders combination. However, our natural binder makes printed parts particularly suitable for outdoor use, stable to atmospheric agents and functional even in underwater environments.
