The use of EGR (Exhaust Gas Recirculation) can help engine manufacturers to keep under control the emissions in order to accomplish to the Euro 4 requirements. In order to improve EGR system VM Motori S.p.A. (Cento, FE - ITALY) decided to test different alternative INTAKE MANIFOLDS. The study was performed using 3 different models, made by C.R.P. Technology in WINDFORM®XT, the latest carbon fibres filled material, for RP Laser Sintering systems.

Gallardo Headlight Washer Cover Flap

The interest of Lamborghini in components made with the rapid prototyping technology has found its origin in requirement of solving the problem for immediate delivery of 100 Gallardo’s model to the first dealers and customers, the pre-production models. The parts in consideration were the headlight washer cover flap.

CRP, Turning point in the creation of racing engines: structural parts made by laser sintering

The new challenge is the optimisation of the CAMSHAFT COVER for the newest Ilmor engine, racing in the 2007 MotoGP. The cover is the structural part that supports the bearing of the camshaft (the camshaft usually runs at about 19000 rpm), directly applied on the 4 stroke 800cc engine head.

RM application on racing engine: reed valve made by flexible Windform® FX and SLS Technology
Let’s talk about the the new project developed (right now being in a testing and improving phase) by CRP Technology’s RP Department in collaboration with CRP Racing: a 125cc bike reed valve made by the new flexible material Windform® FX and SLS technology.

Personalised Manufacturing – Custom made sports car

Fused Deposition Modelling opens a whole new world of possibilities for us. Using this technology to produce parts instead of injection moulding, allows us to make design changes on the move, by simply updating the file. Immediately, parts are ready for production.

DIRECT METAL LASER-SINTERING (DMLS) enables Sentriloc to overcome temporary bottleneck.

To create a chair that combines his artistic flair with precise mechanical characteristics.
The resulting data was then used to drive a laser-sintering machine, which creates the product in sections by fusing successive layers of plastic powder

The object of this case study was to let consumers, in this case electronic circuit designers, design their own product. A parametric model was designed in SolidWorks. This model is a macro and user can run this macro as a program. They can adjust the general dimensions of an enclosure, and add features, like a round hole, or a rectangle cut-out. Finally, the can export the file as an .STL and e-mail it to a production facility.
This program is suitable for almost any circuit board you can imagine.

The case describes reconstruction of a skull defect in a youg girl, which suffered a car accident with loss of large part of her right skull. The implant was made out of medical grade Ti by Electron Beam Melting. The implant was designed by U Maastricht and the operation performed by Dr. Jules Poukens, dep. Cranio-maxillofacial Surgery at the University Hospital AZM.

The component were design to be produced only by a layer manufacturing process, in this case, SLS. Two components where integrated in one, and the axys was integrated to improve assembly process. The parts where hollow inside to reduced the weigth.

In this joint case study we present the redesign and usage of the exact geometries of a human aorta for research and testing studies (IDEE) by the RM production with the biocompatible, soft and flexible stereolithography material FlexSL(R) SE-25 (3mat)

Porous implants and scaffolds from nitinol and titanium.

It was shown high selectivity our filters by the gas and oil of centrifugal pumps, which included in the setup of shipped hydro seal electromotor.

Main requirement here is low permeability on liquids (oil, crude oil, water) and sufficiently good permeability on gases.

Possibility of governing characteristics of filter (membrane) on the micro and meso level, wide prospects of introduction in the porous filter structure of nano size catalysts, active additives and others.

Direct RM manufactured Parts for design studies with biocompatible stereolithographic material as functional prototypes for medical technology applications which require the need of a soft-touch and rubber-like material.

This case study represents a direct RM manufactured phantom anatomical head used for accuracy qualification and validation of the producing process in accordance with Quality Management validation tests for medical product applications (ISO 13485).

The integration of sensors and microelectronic components in smallest space is only one application of the RMPD® based 3D-CSP method. Interconnection, packaging and housing merge to a single step. The generative production methods drive new applications of smart system integration, especially in minaturization of medical products, automotive industry and others.

For business solutions in lifesciences RP/RM methods are ideal for development and production of microfluidic systems (lab-on-a-chip systems, dispenser units, high-through-put screening, ...). The outstanding performance of intrinsic hydrophilic and hydrophobic material properties, short redesign cycles and accurate geometries make new solutions possible in the competitive field of lifescience applications.

Tiny plastic parts make tooling prohibitivly expensive. For RM the RMPD®-mask process takes advantage of smallest size. For small gear wheels the production capacity is more than 150,000 pieces per hour and machine, resulting in high through put and low cost. Planet gear wheel are build up monolithic, no assembly required. 

Cavitation and associated effects such as damage, erosion, vibration and noise has always been the main obstacle to the development of high performance turbines and pumps. The proposed part can be successfully utilized to suppress (laminarize) chaotic flow in a thermal convection loop.
