Guide for on-demand 3D models generation

Please see page Guide for On-Demand 3D Model Generation.

Download

The ZIP archive you receive after downloading a model contains the following files:

• One or more 3D files in STL or 3MF format, compatible with common slicers (Cura, PrusaSlicer, Bambu Studio, etc).
• A "values-model" file
• A "license" file
• A "download-hash" file

The dd suffix found in some filenames and in the ZIP archive name, for example dd840, refers to the download ID, which in this example is number 840. Each download is assigned a unique dd suffix.

Each file serves a purpose. Make sure to keep them all.

STL or 3MF 3D File(s)

STL is the "classic" 3D printing format. 3MF is a more recent format that includes more information and capabilities than STL.

If the generated model includes multiple objects forming a single unit, the file names are distinguished using the "nb" attribute:

"values-model" File

The "values-model" file lists the parameter values of the downloaded 3D model. For example:

#1 width: 50 mm
#2 length: 140 mm
#3 thickness: 20 mm
#4 shape (0:square,1:circle): 0
#5 transition (0:right,1:rounded): 1
#6 fillet radius: 0 mm
#7 hole diameter: 4 mm

To see the full details of these parameters, you can search for the model by ID and view each parameter in the "Parameter Illustration" section.

"license" File

This file specifies the license associated with your download. It is therefore especially important.

A link to the official license description is included.

You can also visit our license page.

"download-hash" File

This file contains a fingerprint of your download’s attributes. It serves as a verification code for the authenticity of your download.

Template, Parameter, Model and Object Concepts

The concepts of template, parameter, model, and object are particularly important on iteration3d.fr.

A template is a kind of pattern, a "mold" that describes one or more 3D shapes forming a "whole".

This "mold" has characteristics that can be modified. This is where the concept of parameter comes into play. Each template has parameters whose values can be changed.

A model is the result of applying the parameters to a template.

Finally, a model can be made up of multiple objects. One of the best examples is a case made up of a base (the "box") and a lid (see the template Round box with lid ).

If we take the example of a case with a lid:

• The 3D shape "case with lid" is the template for which parameters (length, width, height, etc.) are defined.
• A "100×40×30 mm case with lid" is the unique model obtained by applying specific parameter values to the template.
• This "100×40×30 mm case with lid" consists of two objects forming a whole: the "box" object + the "lid" object.

Model Search

Search by Parameter Values

Each template page lets you search for models based on specific parameter values. Please note that not all parameters may be available for search.

For each searchable parameter, the minimum and maximum values are displayed. These values reflect the range of models currently available in the database. You can enter values outside these ranges. If on-demand generation is available for this template, you will be offered the option to generate a model based on your dimensions.

Results are ranked from most relevant to least.

You are not required to fill in all parameters—far from it. If no relevant results are found, try again by entering only the most important parameters for your needs.

Search by ID or Generation Code

Searching for a 3D model by ID is useful if one of your contacts has only provided the model number (for example #800) or if you want to view the parameter representation after a download. Searching by ID allows you to understand the meaning of each value (#1, #2, etc.).

Searching by generation code (for example A9-K9-G4-F6) allows you to access a model after it has been generated.

Both types of search are available on this page Model Search.
