Übersetzung für "Material modeling" in Deutsch

An extensive material library facilitates modeling of composite cross-sections.

Conventional modeling material 6 having a smooth surface can, however, also be used.

At the beginning of the project, the material characterization and modeling are in the foreground.

Manufacture of the object is then not limited by exclusively alternating delivery of modeling material.

The modeling material used is generally present in solid form, usually in the form of a filament strand.

Modeling material: ABS Plus plastic in standard ivory colour (other colours can be ordered upon accord).

If a specimen as described in Example 1 is made from the modeling material according to this example and filled with noble metal, the casting has a perfectly smooth surface (i.e. no burning residue whatever) and exhibits no casting flashes at all at the corners and edges of the casting.

Its shell is made of a flexible rubber material, modeling is also very similar to the toy building blocks, non-slip design feel comfortable.

The process as claimed in claim 17, wherein the dental material is selected from the group consisting of a cured filling material, a core buildup material, a temporary crown and bridge material, a luting cement, a relining material, a dental material, a modeling material, a base material, a covering composition for gingiva protection, a prosthetic material, a material for a temporary supraconstruction for a dental implant or a core for a temporary supraconstruction, an inlay, an onlay, and a veneer.

Delivery of the modeling material to the extruder unit is accomplished in both cases with the aid of drivable feed elements, for example transport rollers, gears, or the like gripping on opposite sides of the filament.

For various reasons, for example when more than one modeling material is to be processed in order to build an object, it is advantageous if the 3D printer comprises a tool head having multiple extruder tools.

For example, the first extruder tool can melt a first modeling material, and a second extruder tool can melt a second modeling material different from the first material.

If the first modeling material is used for the actual object, the second modeling material can serve, for example, to construct supporting structures that can easily be removed again after the object has cured.

Typically at least one of the tools is an extruder tool for melting a modeling material suitable for building the object in layers.

Liquefaction and extrusion of modeling material 6 take place in extrusion units 12 of extruder tools 4, 5 .

In the context of the present invention preferable methods used for producing models (M) are for example milling, stereolithography, laser sintering, laser fusion, 3D printing and fused deposition modeling (FDM), wherein the combustion residue of the modeling material is preferably less than 0.1% (see EN ISO 15854:2005 (D)).

Once the modeling material has been extruded, it cools and solidifies, and the individual layers become joined to form the desired three-dimensional object.

In a variant of these embodiments it is not the entire tool but instead only a drive element of that tool, for example in the case of an extruder tool a transport roller or a gear that serves to feed the modeling material, that is transferred from an idle position in which the drive element of the tool is not operatively connected to the drive system into a working position in which the drive element of the tool is operatively connected to the drive system, and for that purpose is moved relative to the drive shaft, in order to establish the operative connection between that drive element of the tool and the drive system.
