Printer Volumes

For single parts we can print within the following printers volume. Any larger parts can be broken down into a 3d puzzle and assemble later.

Layer Height

Layer height is an important design parameter that impacts the printing time, cost, visual appearance and physical properties of a printed part. The thickness of each layer determines the resolution of a print. Lower layer height typically results in parts with smoother surfaces. The impact of layer height is more noticeable on curves and angles and is less prominent on straight vertical walls, due to the layer-by-layer nature of 3D printing.

Infill (FDM)

FDM 3D printed parts are usually printed with a low density infill. Although the strength of a design is directly related to infill percentage.

Empty/Hollow Parts (SLA)

Hollow parts are required to print with the SLA printers when a particular model has a large massing. This process helps to save on material usage and also makes the print more likely to succeed as it needs less resistance when is doing the peeling process between layers.

In the case of hollow or empty parts, at least 2 holes of 2.5 mm in diameter must be drawn to allow for the uncured resin to be discharged.

Support

Depending on the specific 3D Printing technology and the complexity of the 3D model, a 3D model might require support structure. Support structures will have an impact on surface finish as they require post-processing work to remove, resulting in blemishes or surface roughness. Orientation also plays an important role in where support will be located.

FDMSLA
A feature printed with an overhang beyond 45° can sag, therefore requires support material beneath it to hold it up. A bridge over 10 mm long, generally requires support to give an accurate surface finish.SLA printers require the use of supports in most cases. If the model has overhangs beyond 60 degrees the print will fail.

Tolerances

Minimum Thickness

SLA and FDM technologies can manage very thin walls but to in order to provide a quality product we only print walls with a minimum thickness of 1 mm for the SLA and 1.2 mm for FDM printers. If the model is uploaded with thinner walls then the above mention the model will fail to upload and you may need to contact us.

Mating Connections

Parts with mating connections need to be 0.5 between every wall for the SLA printers and 1 mm gap between every wall for the FDM printers.
Only files with SINGLE parts are accepted

Text, Logos, Embossed and Debossed Features

To get the best results we suggest to keep the elements of these features at least: • 2 mm in height or thickness for the FDM printers
• 0.5 mm for the SLA printers.

Slots

A 1 mm gap between walls is required, proportional to the height of the walls.
