| Minimum wall thickness (flexible) | 1.5mm |
| Maximum wall thickness* | 9mm* |
| Minimum wall thickness particular design aspects | 2mm |
* We do not recommend wall thickness above 9mm as thicker walls can create manufacturing issues, such as deformation, surface aspect issues – Hollowing your parts should solve this issue. Feel free to contact us if you need help to proceed with making your part hollow.
The walls of your design must adhere to a minimum thickness of 1.5mm in order to guarantee the structure will not break. If the walls of your model are less than 1.5mm, you can add a support structure to maintain stability.
For an object that is sure to be solid, a minimum thickness of 2 mm is recommended.
Sculpteo offers an online solidity check tool which highlights parts of the print that may be too thin for a print. From there you are able to tweak your design in order to create an object that is an appropriate thickness. To use it, you just need to upload your 3D file, select your material and click on “Verification” tab.
It is also important to keep in mind that the object is to be printed into real life. Thus if a thin aspect is supporting something that is too heavy for it, it may break – even though it is possible within the physics provided by your 3D modeling software. We recommend adding a bit of thickness to the places that will get a lot of handling, or that support the most weight.
Keep in mind that our solidity check tool does not detect physical aberrations such as floating parts, unstable position, parts supporting too much weight relative to their thickness, etc. Particular care must be given to the geometry of your design and the most stressed parts must be thickened.
| Minimum size of details | 1 mm |
| Minimum size of text | 1 mm |
| Enlargement ratio | 1/1 |
A detail’s minimum precision is mainly determined by the resolution of our printers. However, during the cleaning process, a fine layer of detail can also be lost. In order for a detail and text to be visible we recommend following our recommended sizes at the very least. To ensure a better powder removal (thus a better detail precision), the width of your details must be at least as big as depth.
| Enclosed parts ? | Yes |
| Interlocking parts ? | Yes |
Our SLS PA12 GF material has the ability to be printed for some complex designs. An example of a complex design is a volume enclosed within another volume or with articulations. Our glass-filled Nylon 3D printers have the ability to print a fully interlocked object out of the printer, with no support structures to remove.
| Minimum spacing between fixed walls | 0.5 mm |
| Minimum clearance between parts | 0.5 mm |
For a successful 3D print a minimum clearance between objects is required to allow the excess of material to be sand blown out. If this space is not left within the design, the object will be a solid. This is particularly important for articulated objects – as the space left between the walls will define the object’s ability to move.
Clearance should be at least 0.5 mm and depends on your object’s size. For big sizes, the clearance should be greater. The heated zone of your object depends on the size, the larger the object the more time it will be exposed to high temperature: if the space left between the walls is too small, it will be weld because of heat spreading.
| Assembly ? | Yes |
| Minimum space | 0.5 mm |
Objects printed in Nylon PA12 Glass-filled can be printed to be assembled. As long as a width of at least 0.5 mm is left between the different parts of the object.
Our online hollowing optimization tool has the ability to greatly reduce the price of a print by reducing the amount of material used.
Using the tool requires adding two holes to your model, which will serve as the drain for the excess powder material within the object. The minimum size of these holes is determined by our website. Otherwise it is possible to hollow your object manually in your 3D modeling software.
| Files with Multiple Objects? | No |
It is not possible to 3D print a 3D file containing several objects with SLS PA12 GF.
