Grosor de las paredes
In 3D Printing, wall thickness refers to the distance between one surface of your part and the opposite sheer surface. The walls of parts need at least 1.2 mm thickness.
However, overly thick walls are not advisable either as they use more material than you need and run the risk of deforming the part. If your design has wall thicknesses greater than 6 mm, we fill the wall thickness with sparse structures. This helps us save material and minimize the likelihood of warpage.
Calidad de la superficie y orientación
Many of the characteristics of your 3D print will depend on the Fused Deposition Modeling (FDM) process. Because your part will be printed layer by layer, the printing orientation will influence its surface quality and strength. On the left, you can see two parts of the same shape but built with different orientations.
The horizontally printed model clearly shows the “staircase” effect of the printing process. Its surface will be similar to that of a topographic map. If the part is printed vertically, the surface quality will be better.
Think about which surface needs to have the best finish and choose the orientation accordingly when printing.
Because your part is built up layer by layer, it will always have “weak points” caused by its printing orientation. These weak points can cause thin external elements of your design to easily break off. Therefore, avoid features on your part that are parallel to the base or bottom plane and that will require strength to support them.
Fused Deposition Modeling (FDM) is one of the 3D printing processes (for plastics) with the highest dimensional accuracy. Dimensional accuracy doesn’t relate to the detail of your part but to the deviation from the nominal size. The standard accuracy we offer for Ultem 9085 is 0.15 % with a lower limit on ± 0.2 mm.
Fused Deposition Modeling (FDM) takes place on a building platform. Since parts will be “built in mid-air”, they must be attached to the supporting platform to prevent them from collapsing. This attachment is referred to as the “support” and is required for any part built using this technology. In addition to keeping the part in place, it also enables the construction of overhanging elements. After the building process is complete, the support is manually removed.
Parts that have sections narrower than 45° must be supported. The support is required to keep your part in place and prevent it from collapsing while being printed. In the example on the left, the bottom of the vase must be supported because it is narrower than 45°. The rest of the design doesn’t require extra support because it is wider than a 45° angle.
The 45° rule also applies to the interior of your part. Any model with an interior section below 45° must be supported. In the example on the left, the model on top must be supported to prevent it from collapsing during the printing process.
Regla de 45 °
This diagram shows you when a part requires support. The “self-supporting” or “safe” zone does not require any support to print the part. For most parts, this area ranges from 135° to 45°. When designing an object you would like to print in Ultem 9085, keep this safe zone in mind if you are concerned your part will require support to be constructed.
¿Piezas entrelazadas o juego entre piezas?
It is not possible to print interlocking and moving parts (e.g. a ball bearing) in Ultem 9085 because the support material used for Ultem 9085 is not water-soluble. By contrast, ABS materials and PC-ABS use soluble support materials.
Detalles en texturas o grabados
In general, engraved text or details are preferable to embossed text or details. For engraved text or surface details, we recommend letters with a minimum line thickness of 1 mm and a depth of 0.3 mm. For embossed text and surface details, we recommend that letters have a line thickness of at least 2.5 mm and a depth of at least 0.5 mm.
