Technological Platforms - Prototyping & Reverse Engineering - CDTA

Technological Prototyping Platform

” Potentiality, ability to support innovation, creation and technology transfer ”

The CDTA Technology Prototyping Platform has, to ensure to its partners as the ministry of Higher Education and Scientific Research sector, the socio-economic and industrial sector different services. Such as the manufacture of Prototypes, Experimentation, Demonstration, Technical Assistance and Consulting, as well as Practical Training of Students,   skills upgrading and retraining.

Our engineers and technicians have diverse skills and backgrounds based on the complementarity of multidisciplinary knowledge, both scientific and technical, which are related to mechanical and industrial engineering.

Outfit with digital production equipment, rapid prototyping, additive manufacturing as well as design tools, 3D metrology scanning and control. The CDTA technological prototyping platform offers to these partners benefits with veruy high added value.

1. Reverse engineering,

Equipped with high-precision equipment, we offer a 3D scan service, 3D reading with a precision of up to 0.8 microns.
3D scan, three-dimensional on-site survey, retro-modeling, dimensional control, form and assembly, complex molded parts, sculpted, machined, boiler, injected, extruded, thermo-formed, welded,…

 

2. Mechanical system study

We provide range from concept design through detailed engineering, analysis, and prototyping. Our services are used by companies in a variety of industries such as military, electronics, industrial automation, power, and manufacturing.

– 3D Modeling & 2D CAD
– Design optimization
–  Industrial design
– sheet metal design
– Rapid prototyping
– Plastics design

3 Additive manufacturing

Stratoconception ®  is the additive manufacturing method of solid type / solid which permits the fabrication, layer by layer, of an object drawn in CAD, without any rupture of the digital channel, The method involves the automatic decomposition of the object into a series of complementary elementary layers called strata, in which are placed locating inserts and reinforcements. Each of these layers is directly in range and manufactured by rapid micro milling, laser cutting, for wire cutting, or any other means of cutting from all board materials. All these layers are then positioned by inserts, bridges or by interlocking members and assembled to reconstruct the final part.

The assembly of the strata is taken into account at the design stage to ensure resistance to mechanical stress during use. The inserts are used both for positioning pins and links between strata. In the case of thin-walled parts, they are placed outside the room through breakable bridges.

Advantages :
– easy supply of material at a competitive industrial prices (no matter captive)
– Many types of parts made by this process: models, functional prototypes and technology, molds, models, machinery, tools …
– production time reduced prototypes and tooling
– non-polluting process that optimizes the material and allows the recycling of waste
