CAD Files

Do I need a 3D model for 3D printing?

It is possible to produce a 3D part from a 2D drawing but this will require intervention by RICOH engineers to convert the file from 2D into 3D data. Once this has been carried out a quote can be generated.
If you have 2D CAD for conversion, please email to RapidFab@ricoh-rpl.com (this may be carried out free of charge depending on complexity)

What type of CAD files do I require for a 3D model?

At RICOH we can accept most types of native CAD files but STEP or STL are preferred. When 3D printing any CAD data it is converted into a STL file and then sliced prior to printing on the relevant 3D printing equipment.

3D printing applications

What applications can I use my 3D model with?

With the extensive number of materials available for 3D printing the applications are endless. Components are used extensively for end user components in motor sport, aerospace, medical, low volume automotive as well as architectural models, jigs, fixture. Some materials such as the RICOH Polypropylene are used in assemble trials in the automotive sector as its material properties are so close to the end user material.

Materials

Does the Polypropylene need any post treatment to make it water tight?

When the Polypropylene components are removed from the AM machine, they require a blast to remove the excess powder and then they are good to go. No additional coatings or treatments are required to make them water tight.

What is the minimum wall thickness for a water tight Polypropylene vessel?

The minimum wall thickness for any component will be subject to the end applications and will be influenced by the temperature and pressures the end part will be subjected to. If a component is not subjected to increased pressure and kept bellow a temperature of 100℃ we would suggest a wall no thinner than 1mm.

Is the Polypropylene chemical resistant?

The polypropylene manufacture on the Ricoh machines exhibits the same chemical resistance as a conventional injection moulded component. We have had components subjected to long term contact with oil at elevated temperatures, with no significant affect on the Polypropylene AM component.

Can I recycle my Polypropylene model?

The Polypropylene AM models have the same properties as an injection moulded component and can therefore be recycled using your local recycling protocols.
