Validation

When you see this symbol validated in the model, is that Tridimensia has verified that there are no error that may affect the outcome of printing.

When you see this symbol warning in the model, is that Tridimensia has detected some error that can affect the outcome of their printing.

Whenever any models is damaged cannot be used for 3D printing.

For example, a design may contain surfaces with borders, that do not enclose a volume. These surfaces have no thickness and therefore cannot be constructed.

Sometimes, the entire surface is not oriented consistently, and does not clearly separate the inside from the outside of the object. Most of the time, this issue is fixed by flipping the problematic facets.

Other damage for part is Degenerate faces that are triangles which have no surface or only minimal Surface. As they do not construct any surface, they usually are unnecessary. Degenerate faces in a file principally do not result in bad parts when manufactured, but they may dramatically increase the number of corner points and hatches in the slice files necessary for the production This may cause much longer calculation and production times.

The validation us provides information about potential damage showing the number of holes, boundary edges, flipped triangles and bad edges, specifies the overall length of boundary edges and checks, if the part is closed and orientable. Thus, we can find out, if a part requires repair and which kind of repair it requires.


The Tridimensia validation process is performed in two different levels that allow us in most cases that the piece has no previous problem for good printing.




repair
Repair

Once detected problems in the mesh of a model, Tridimensia can try to fix it.

For example This repair enables you to close holes or to connect edges add new triangles. If they are not connected, two triangles are inserted. If any border edges of the new triangles are neighboring other border edges, these are connected automatically.

Other solution could be enables refine the triangle mesh inserting new corner points. New edges are inserted, connecting this point with the three corner points of the old triangle. So, one triangle is split into three o If a node is placed on an edge, both adjacent triangles are split into two triangles.


The Tridimensia repair process is performed in two different levels that allow us in most cases that the piece has no previous problem for good printing. This is a simple repair automatically fixes flipped triangles and first closes trivial holes and then all holes.

Of all forms we recommend to use a program of laminated that in his process of creating the file of instructions of the printer, verifies the files that could be corrupt. Tridimensia recommends the software CURA is open source (http://software.ultimaker.com/).




virtual print
Simulation

The simulation shows which are the instructions that our 3D printer will run to print the model.

This simulation is performed according to a standard configuration for generic PLA or ABS of RepRap printer capable of printing plastic objects.

The main advantage of simulating the impression is that it allows us to establish the production process model. This information is known in advance allows us to vary parameters in the way manufacturing is realize.

For example, increasing wall thickness or to create media that protect the integrity of the part in the cooling process.

Also will allow us to choose which the best pespective to print the piece is or whether or not to use material support or where to use it. The perspective refers to the direction from which a project is printing.









Description

In the description section we can obtain specific information about the model you chose to print in two respects:

The first refers to the physical data model. In this field we can know:

In the second aspect concerning the printing of the model is analyzed. Among others you will learn:
