Dimensions

The maximum size of the printing area is 380x380x290 mm. Largest part can be printed by splitting

PRODUCTION TIME

• Minimum 2-3 Working Days
   

Our fastest production time for Nylon is 2-3 Working Days. This depends upon the size, quantity, quality of 3D data, and the production space available at the time of your request. We operate on a first come first served basis and have a cut off point at 3pm each day to begin collating and sending the data to the printers.

3D PRINTING PRICE

The cost of Nylon is primarily based on the overall height of the parts once they have been positioned to fit as low as possible within our maximum build chamber, with a small charge per any additional parts within that height. For multiple parts the cheapest and most efficient way is to use our Nylon Container System. For an estimate on a single part you can Contact Us and we will give you a quote.

DIMENSIONAL ACCURACY

• +/- 0.35mm (+/- 35microns)

Generally our machines will print with a higher accuracy, they are calibrated up to ±0.15% on the X and Y axis and build with 0.1mm layers on the Z axis.

We find that some shapes and forms can be more forgiving than others, depending on the overall size, form, density, and orientation. If you are working within these tolerances we recommend you contact us first to discuss your project.

SHELL THICKNESS

• ~ 0.7 - 3mm (70 - 30 microns)

The outer shell thickness all depends on how you need to object to perform and function. Parts under 3mm may contain a degree of flexibility dependant on the shape support and structure. Anything above 3mm provides enough strength for all forms and sizes to remain rigid.

Escape Holes

It is important to remember that Nylon SLS is a powder based technology, meaning that powder can become trapped inside hollow parts if there is no hole to remove the powder from.

MAXIMUM BUILD SIZE

• 380 X 380 X 284mm

If your project exceeds this size, then you may wish to reduce the scale of the object, or separate it into parts so it can be reassembled afterwards.

We would often recommend adding tapered location pins and corresponding holes with a clearance to accurately locate and connect parts afterwards.

TEXTURE DETAILS

The texture of Nylon has been accurately compared to a Extra Strong Mint, or a 320 grit sand paper. This texture is a result of the outer grains of nylon powder adhering to the outer surface of the sintered Nylon.
All parts will have a grain of 0.1mm layers in the Z axis, which is often invisible to the eye and only becomes more visible on gradual curves. 

MINIMUM WALL THICKNESS

• 0.8mm (80 microns)

Generally our machines will print with a higher accuracy, they are calibrated up to ±0.15% on the X and Y axis and build with 0.1mm layers on the Z axis. We find that some shapes and forms can be more forgiving than others, depending on the overall size, form, density, and orientation. If you are working within these tolerances we recommend you contact us first to discuss your project.

CLEARANCE BETWEEN PARTS

• ~ 0.4mm (40 microns)

This is used to determine how close 2 objects or surfaces can be printed next to each other. If they are much closer than this, then the surfaces can begin to fuse together, distort or it may become impossible to remove the unsintered powder between the separate parts.

TRAPPED POWDER

Deep holes or recess’s can often create problems when removing the unsintered powder. We have techniques to avoid this before printing, so let us know if this is a concern and we can discuss it further with you.

DYEING

POA

We can dye Nylon SLS objects in a range of 17 standard colours. This is an industrial process, developed specifically for the material which produces an even, consistent and colour fast result.

SPRAYING

POA

mjf parts can be spray painted, but they will require Vibro Finishing and priming before applying a final spray coat. We do not offer this as a service but we can provide advice on how to do this.
