BOUNDING BOX

Maximum
284 x 380 x 380 mm (Gray Natural and Black Smooth)
210 x 210 x 360 mm (Black Natural)
Minimum
7.0 x 7.0 x 7.0 mm & X + Y + Z > 9 mm (Natural)
10 x 10 x 10 mm (Smooth)

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

WALL THICKNESS

Min Supported Wall Thickness
0.4 mm (Natural)
1.5 mm (Smooth)
Min Unsupported Wall Thickness
0.5 mm (Natural)
1.5 mm (Smooth)
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

Min Supported Wires
0.8 mm (Natural)
1.5 mm (Smooth)
Min Unsupported Wires
0.9 mm (Natural)
1.5 mm (Smooth)

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
Natural: 0.2 mm high & wide (0.4 mm high & wide for readable text, logos, and icons)
Smooth: 0.5 mm wide, 0.3 mm high
Min engraved detail
Natural: 0.2 mm high & wide (0.4 mm high & wide for readable text, logos, and icons)
Smooth: 0.4 mm wide, 0.3 mm deep

LDsports 开户We recommend these minimum measurements for details like embossing or engraving, based on printer resolution. Although 0.2mm details will show up in this material, we find that text with a width and height of 0.4mm shows up most clearly.

ESCAPE HOLES

Single Escape Hole Diameter
4.0 mm (Natural)
10 mm (Smooth)
Multiple Escape Hole Diameter
2.0 mm (Natural)
8.0 mm (Smooth)

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

0.6 mm (Natural)
5.0 mm (Smooth)

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

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 mass on either side. For this reason, they need to be thicker than our minimum wire thickness.

INTERLOCKING AND ENCLOSED PARTS ?

Natural: Yes, interlocking parts are possible with this material.
LDsports 开户Smooth: No, the smoothing process will fuse interlocking parts together.

MULTIPLE PARTS ?

Natural: Up to 250.
LDsports 开户 Smooth: Up to 10.

ACCURACY

Natural:±0.25 mm + 0.1% of the length
For example: a product with dimensions of 50x50x100 mm can be 0.25 mm + 0.001*100 mm = 0.35 mm bigger or smaller in any direction.
Smooth: ±0.4% (with a lower limit of ±0.2 mm)

DESIGN TIPS

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. The smooth finish can help reduce the visibility of these lines although some may still be visible.

LDsports 开户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.

LDsports 开户Surface Details

Details like small text and patterns show up best in Black. Gray parts have the same level of detail, but variation in the surface color can obscure surface details in your model.

LDsports 开户Sharp Edges

Edges and corners may be sharp and slightly raised from the surface by about 0.1 to 0.2 mm. If your model has many faces with edges and/or corners, the corners of one side may show more of this effect due to how it was oriented during printing. Adding a fillet with a radius of 3 mm or more will reduce this effect of raised edges.

Avoid "Spikes"

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

LDsports 开户Holes & Small Holes

We cannot clean holes that are too small compared 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.

Color

LDsports 开户MJF Plastic has a black core, which can be seen if a model is broken or scratched. Gray displays a light grey colour which, can vary in uniformity and shade. This can make models look slightly uneven and may vary between similar models. If a model's flat surface is oriented upwards, it can be subject to a significantly darker batch of grey in the center.

Pores

Occasionally, products may have small pores. This porosity can weaken the strength of the product, leading to more brittle parts. Pores are most prevalent in thin wires and on the edges of flat surfaces. To reduce the risk of pores, we recommend making round wires at least 3 mm thick. Additionally, they are less likely to occur on square beams than on round wires. We recommend 2 mm thick square beams.

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 be rougherst and the bottom surface will be smoothest.

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

What is the minimum price per part?

Natural: The minimum price per part is $7.50
LDsports 开户Smooth: The minimum price per part is $15
