Gamechanger for Additive Manufacturing

The innovative 4D_Additive Manufacturing Software Suite sets new standards. Now for the first time 3D models from all common CAD formats can be read and prepared for additive manufacturing processes directly as an exact, intelligent and light B-Rep geometry.

4D_Additive reads CAD data from 24 different formats such as CATIA, NX, SOLIDWORKS, Creo, Inventor, STEP and JT as exact B-Rep geometry including all product manufacturing information (PMI), attributes, and design history. In addition also triangulated formats such as stl, obj and 3mf can be read in and perfectly processed.

The CAD models optimized for 3D printing and nested on the build plates can be saved in all common formats such as amf, 3mf and STL as well as in common slicing formats cli, sli, abf, svg, sls, usf and g-code.

NECO the expertise for additive and subtractive manufacturing

"NECO is pleased to use 4D Additive Manufacturing pre-processing software for its unique texturing module, lattice tools, and nesting."

States Robert Collier, President of National Equipment Corporation.

Nesting and Optimization

Intelligent 2D and 3D nesting capabilities with multiprocessor computation ensures fast automatic fill up with optimal build volume utilization for all machine types available in the database, as well as for customized machine types. The extremely quick nesting function of 4D_Additive uses a superfast multiprocessing and provides a maximum of automation.

Especially for powder bed processes, such as HP MultiJet Fusion, fully automatic nesting offers great benefits, by eliminating time-consuming manual work is reflected in the price of the parts. The user can specify the respective number of parts as well as a minimum distance. The construction volume is then filled automatically, so that an optimized number of components is accommodated on the platform.

The relative density of the installation space is predefined in favor of a sensible heat management in order to optimize quality and costs. Here, large parts can also be positioned by manually and then automatically add a large number of smaller components. For the manual arrangement of the components in the build space, the system offers a collision check that reliably indicates if parts touch each other or fall below the desired minimum distance.




Textures revolutionize part design

The innovative Texture Module, allows the user to access more than 5,000 different texture surface structures. 4D_Additives makes it easy to define textures on the CAD model. Simply select the desired surface areas and then apply texture from the database. The size, resolution, position and height of the structure can be visually adjusted, whereby a rendered, photo-realistic representation of the model facilitates the work. The software automatically ensures distortion-free projection of the grain over surface boundaries. The precise graphical representation allows real-time assessment of the designed geometry and ignites the creative process of designing new parts.

CAD Engineering Standard for precise Additive Manufacturing

The robust B-Rep kernel of 4D_Additive enables quality check, repair and preparation of models in accordance to CAD-engineering standards which are based on exact geometry. In conventional 3D printing tools, CAD models are often already triangulated during the reading process and thus converted into an approximate and imprecise STL description so that further operations like a repair of modelling errors, result in significant deviations from the original shape.

4D_Additive, on the other hand, enables the check, repair and handling of the exact, original B-Rep data according to VDA 4755/2 standard and thus for the first time a continuous additive manufacturing process that is in line with CAD Engineering Standard.

Sophisticated checking and healing functions analyze the CAD models and automatically eliminate gaps, overlaps, mini-elements, twisted faces and other types of errors. Errors that are not automatically correctable, e.g. Knife edges, are displayed clearly and can be corrected within seconds by means of easy-to-use clean-up and modeling functions. 4D_Additive ensures the production of precise quality models.

Advanced geometry analysis

For the best possible heat distribution, the software automatically indicates massive zones that are areas with very large wall thicknesses, in which a heat concentration possibly takes place. These areas are highlighted in color and provide information for future component design or positioning of the component.

The wall thickness checker on the other hand can be used to find the areas that are critical for certain processes because of very small wall thicknesses. In addition, the gap measurement i.e., a backlash test makes it possible to detect problem areas and details that are too small for the respective method, such as holes with too small a diameter.

Machine and Technology Database

Common machine types with the respective build space and technology parameters such as layer thickness, smallest possible detailing like a minimum hole diameter as well as costs factors are stored in the database. The database can be supplemented with user-defined machines and technology parameters.

Automatic part orientation

A special analysis function makes it possible to visualize the expected surface quality in real time and to achieve optimum orientation of the part within a very short space of time. A fully automatic part orientation through the Multi Criteria Positioning function serves an optimal surface quality of selected areas or for a minimum of support geometry volume and/or costs of the part. The automatic function also helps inexperienced users and drives the automation of additive manufacturing processes.

Support generation

For metal printing processes and also for other processes, a wide variety of special support structures can be generated in automatic and/or manual mode. The automatic analysis identifies areas where support structures are needed for manufacturing. The support structures of various shapes can be changed and customized by the user.

Cutting parts

Components that are too large for the space of a machine, can be split with different patterns such as T-shape, dovetail or puzzle shape. In addition to the shape also the position of the splitting plane can be defined easily on the model. The functions then works automatically, creating two solid models that can be perfectly mated after printing.

Hollow and lattice structures

To save material and reduce heat input, a massive model can be hollowed for a user defined wall thickness at the push of a button. The areas of accumulations of material previously found through the Massive Zone test can be dehumidified to reduce mass and heat input.

The excavated models can be filled with different lattice patterns of any size. The calculation using multiprocessors is extremely fast. In this case, the "outer" model can also be replaced with Lattice structures, whereby the previously defined areas, such as functional areas, remain as the original geometry.For the filling of the lattice areas, different patterns can be selected - such as honeycomb, octet or center point.

Slicing with multiprocessor

The speed of slicing is unrivaled due to the multiprocessor calculation and using the exact B-Rep it is also possible to generate and save exact slicing curves as vector graphics. The default slicing parameters are taken directly from the technology database. In addition, different hatching patterns are available. The results can be saved in general slicing formats like abf, cli, clf, cls, cmb, slc, sli, svg, sls, ssl, usf and g-code.
