BOUNDING BOX

Maximum
290mm x 290mm x 600mm
Minimum
X + Y + Z ≥ 7.5 mm

LDsports 开户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.

WALL THICKNESS

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

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.

WIRES

Minimum Supported Wires
0.7mm
Minimum Unsupported Wires
1mm

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.

SURFACE DETAILS

Min embossed detail
0.4mm high & wide
Min engraved detail
0.4mm deep & wide

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

ESCAPE HOLES

Single Escape Hole Diameter
4.0 mm
Multiple Escape Hole Diameter
2.0 mm

Pressurized air is used to blast excess powder from models that are hollow, or contain hollow cavities. In order for us to safely do this, escape holes need to be larger than 4.0 mm in diameter. For models larger than 50.00 mm³ we require two or more escape holes at least 2.00 mm in diameter.

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.

CLEARANCE

1.0 mm

Clearance is the space between two parts, e.g. space between gears or a ball and socket joint.

SPRUES

HP Sprues

2 mm thick, attached in at least 2 places per part.

Sprues are wires that keep two models together. Sprues are more likely to break compared to other wires because they typically connect parts with high relative mass on either side. For this reason, they need to be thicker than our minimum wire thickness guidelines.

INTERLOCKING AND ENCLOSED PARTS ?

Yes.

LDsports 开户PA11 is printed with an SLS process that uses a laser to fuse together nylon powder. This enables interlocking parts, as long as the distance between them is greater than the indicated clearance minimum.

MULTIPLE PARTS ?

Up to 250.

ACCURACY

± 0.2 mm

DESIGN TIPS

LDsports 开户Print Lines or "Stepping"

A "staircase" effect, or print lines, can occur on the surface of your print. These can become more pronounced on curved and angled surfaces.

Preventing Warping

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

LDsports 开户Avoid "Spikes"

LDsports 开户If your model has spike-like geometry where the spike is longer than it is wide, it's possible for it to break in the cleaning process.

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. Generally, the top surface will have more visible stepping than the bottom surface. The mating surface and other important features like holes are the most accurate when placed in the horizontal plane.

Holes & Small Holes

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.

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

Laser Lines

LDsports 开户 Our printers operate with two lasers at the same time. If a product in the printer is located in the overlap plane where the two lasers meet, miniscule calibration differences between the lasers may create a visible line on the surface of the product. We aim to arrange products in the printer away from the overlap plane. However, products larger than 33cm long in any direction may be too large to fit in one laser's area, so you may see a visible line along the overlap plane on your product.

PRICING

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 $10 per part.
