Technical dataGuide to utilization

With the following we will briefly and schematically illustrate the principle concepts for the correct use of the materials from the WINDFORM family. In case this guide is not sufficiently exhaustive, we invite you to contact us.

Attention!!
For all information regarding workplace safety and waste disposal, it is compulsory to observe the Safety sheets.
Furthermore the Safety pack, is available to be purchased, collecting all best safety devices for WINDFORM materials.

Shipping of materials

WINDFORM is sold ex-works CRP Technology-Modena, and therefore the shipping should be organised by the purchasing client. CRP, does, however, offer a service which organises pick up from the warehouse once the destination address has been specified. The shipping, the Customs broker and duties, both leaving Italy and entering the destination country, shipment risks and the costs, remain the responsibility of the addressee.

Receiving and storage of materials

WINDFORM is packed in metal bins:

1 Europallet: 80 X 120 cm, 12 bins.

Every metal bin contains:

The metal bins are resealable.

Maintenance

It is advised to keep the full bins in a dry, cool place, away from the sun (temperature between 15-25°C). The sack of Silica Gel is situated between the plastic sack, which contains the material, and the metal bin, and should never come in to contact with the material.

Preparation of the loaded machine

Before loading the sintering machine, the powder contained in the metal bins must be agitated (possibly in the mixer for approx. 10 min.) and sifted with the appropriate sieve mesh, as listed below:

A first, but not only device, could be rolling the metal bin, containing the powder to load in to the machine, on its side.

Attention!!
In this phase a huge quantity of powder is dispersed in to the air and therefore it is important to pay particular attention the the volatile powder, and wear the appropriate protection as indicated on the safety sheet.  One must also pay attention to the powder deposited on the ground which could create an extremely slippery and therefore dangerous surface.

Attention: only for 3D Systems machines, CRP also suggests to take off the linking pin of the lateral metal two-pieces shields and leave only the upper shields, in order to avoid the vibrations due to shields touching the roll.

The build

With the first purchased batch, we will provide a CD with the config. files for the following machines:

Moreover, it is possible to check the GUIDE FOR 3D SYSTEMS MACHINES, derived from CRP's and its collaborators’ experience

Attention!!
The parameters of the  temperature and the laser power in these Config.files are only indicative parameters and it is necessary to adapt them to your machines.
Carry out some tests on some samples in order to find the appropriate parameters!
For other 3D Systems machines and EOS machines it is possible to request specific information at the time of purchase. CRP assures maximum availability in sintering assistance in the eye of Customer Care.

Positioning in the sintering area of .stl files

It is recommended to always give precedence to carrier X, even when the “Cross Fill Scan” parameter of the Part Profile is qualified. CRP, however, does not recommend the qualification of the parameter because, although the production time is accelerated, it does not guarantee the same mechanical performance of the prototypes created with the “Cross Fill Scan” disabled.

Possibility of intervention during the sintering

It’s possible, in some cases, with 3D System machines, to intervene even during the sintering to reach the file.stl and, consequently, optimise the incomplete build, or modify some of the parameters in the case of an error. In particular, from CRP’s experience, it has been found that the “Inner/Outer Ratio” parameter is very important for keeping the temperature in the working area more homogenous.

Recycling

The Powder Quality file, is also available, with the step by step detailed quality instructions.

Extraction of the build

Once the cooldown phase is finished, the machine is opened and the entire cube of powder, where the prototypes are, is extracted, along with the cube of appropriate plexiglass and at the metallic slit. Both are then placed on the cleaning table equipped with on the appropriate aspiration system.

Attention!!
In this phase a huge quantity of powder is dispersed in to the air and therefore it is important to pay particular attention the the volatile powder, and wear the appropriate protection as indicated on the safety sheet. One must also pay attention to the powder deposited on the ground which could create an extremely slippery and therefore dangerous surface. Immediately after the positioning of the build, the entire area around the sintering machine must be cleaned.

Extraction of pieces

One must pay particular attention so as not to cause deformation from an excessive thermal shock in the pieces when being extracted and when being placed on the shelf. It is important to delicately use brushes of all dimensions and hardness to remove as much powder as possible, before placing the prototypes in the sand blasting machine for the final cleaning, before the start of the finishing.

Packing

The packing depends on the type of shipping and the distance to the destination. One must pay particular attention to shipping in humid or very hot vehicles. Regardless of the elevated performance of the mechanics, the pieces with fine and delicate details, must be packed with extreme care and attention.
We highly recommend the use of shipping materials such as “pluriball” and polypropylene  or paper shavings..
