Frequently asked questions

 

Which materials can be printed?

The list is constantly growing and changing. At the moment the following plastics can be printed; ABS, Glass Filled Nylon, Nylon, ABS & PP Simulant, VeroWhite Resin & a Waterclear Resin. Metals, ceramics and rubber simulant materials can also be printed. We can even 3D print in chocolate if you want.

 

What is SLS?

This 3D printing technique produces tough, durable models, usually suitable for product testing however they are not as detailed as SLA.


   

 

What is SLA?

This allows more detailed models to be printed, which tend to be more suitable for aesthetic analysis than testing. They also tend to be more expensive than SLS models.

 

Can I print in the same materials as the one used in final production?

Yes, with FDM printing technology you can print in real ABS or PC polymers, meaning your 3D print will be just as strong as your final product. Which is a great advantage for 3d printing for product testing.

 

How big or small can the object be printed?

Typically most printers maximum size is 30cm x 30cm x 30cm, however for larger objects we can design portions to slot and fix together. However please note that large items are very expensive!
As a rough guide, a shirt button size is approximately the smallest usable sized object you can print.

 

Which file types do you accept?

Currently we can accept the following 2D file types: .dxf, .dwg, .pdf, .jpeg
​Currently we can accept the following 3D file types: .prt, .sldprt (we run a Solidworks 2012 licence), .x_t, .iges, .step

 

Low volume production

3D printing is a perfect tool that can be used for low volume production. A great technique is to create a silicone mould from you 3D print, from this you can mould copies in resins and other materials. Objet have a great PDF tutorial here about silicon moulding of low volume productions.

 

Who owns the design?

We send you the CAD model used to print the 3D object and you own sole rights to this. You can then use the file to 3D print the object with another company if you wish.

 

Can I send Luma3Dprint a design I would like to patent?

Not to start with. If you have an idea you would like to protect with a patent do not let it out into the public domain, that includes us. First we must sign an NDA which protects your idea.
