609 x 711 x 457 mm
3.8 x 3.8 x 3.8 mm

Your model should be within the minimum and maximum bounding box sizes. The maximum bounding box represents the largest model that that we can manufacture. The minimum bounding box size is the smallest dimension in which we can manufacture in this material.


Minimum Supported Wall Thickness
0.4 mm
Minimum Unsupported Wall Thickness
0.5 mm

LDsports 开户A supported wall is connected on at least two sides. Walls in your model must meet the minimum measurements to ensure it survives the printing and cleaning process. Thin walls are prone to warping during printing and are fragile to clean. Objects that meet the minimum requirements may still be rejected based on the geometry in which case our production team will communicate with you if the design needs improvements and can assist you to strengthen your model.


Minimum Supported Wires
0.5 mm
Minimum Unsupported Wires
0.6 mm

LDsports 开户A geometry is considered a wire when it is thinner in both unconnected directions than its length. Wires that are under our suggested minimums are prone to breaking in the cleaning process, or warping.


Min embossed detail
0.3 mm high, 0.4 mm wide
Min engraved detail
0.3 mm deep, 0.3 mm wide

We recommend these minimum measurements for details like embossing or engraving, based on printer resolution.


Single Escape Hole Diameter
5.0 mm
Multiple Escape Hole Diameter
4.0 mm

Hollow cavities will trap liquid resin so escape holes are needed in order for us to completely clean excess resin from a part.

A single escape hole at the end of a cavity will not allow material in the corners near the escape hole to fully escape. So we recommend multiple escape holes at both ends of the cavity.


0.3 mm

Clearance is the space between two parts or features.


No interlocking or enclosed parts may be printed.


Up to 250.



1.3 mm diameter (or thinnest dimension if not circular)

Sprues are wires that hold several parts together and tend to be removed by the customer after receiving the model. Sprues need to be connected to at least two sides of the parts and the support material generated for sprues should not interfere with the models' structures. If sprues are placed above parts will result in rougher surfaces from excess support material than would not be necessary if the parts were printed separately without sprues. Since sprues often support larger masses relative to their size, the sprue thickness should be greater than a standard wire. See "Wires" for more details.

LDsports 开户Print Lines or "Stepping"

Although SLA technology can create very smooth surfaces, a "staircase" effect, or print lines, can occur on the surface of your print, and is more pronounced on curved and angled surfaces.

Preventing Warping

LDsports 开户Making your design more stiff (increasing torsional rigidity) will reduce the risk of warping. Longer walls need to be thicker than short ones.

Support Material

Stereolithography only prints one material at a time. Therefore support structures are printed in the same material as the part and need to be removed when parts are removed from the build plate. Support structures may adhere to the part in several locations depending on part geometry and orientation. After removing the supports, there may still be small nubs or artifacts on the surface of the part from where the supports were previously connected.

LDsports 开户Orientation

Our production team does their best to evaluate your product and orient it to optimize either dimensionally accuracy or aesthetics depending on the application. Support material can leave small markings after removal so aesthetic features will be oriented to limit support contact.


We cannot clean holes that are too small relative to their depth. Additionally, tubes with corners can be difficult to reach and we may not be able to fully clean your model.

LDsports 开户We recommend creating multiple access points to holes and small tubes so that we can properly clean your model.


LDsports 开户How will the price of my model be calculated?

  • Material Volume - the amount of material needed to 3D print your product
  • Machine Volume - the amount of space your product takes inside our 3D printers
  • Number of parts - a part is a piece of a model that can be separated from other pieces of the model
  • Production - associated production costs including labor; quality control; machine maintenance; general utilities; and other supporting services required to 3D print your product

LDsports 开户What is the minimum price per part?

The minimum price is $30 per part.
