SLS Nylon Care Guide
Your parts have arrived! What’s next?
Here is our guide on how to make the most of your 3D prints.
With our new cleaning procedure, finding powder residue on your parts is fast becoming a thing of the past. In the unlikely event that you do find a small build up of powder in a corner somewhere or a small amount of powder coming off the print when you touch it, this is nothing to worry about. Any excess powder can be easily removed with a little soap and water. You can use a coarse brush if you want it really clean. The material may feel porous but it is only the outer 0.2-0.3mm that will retain any moisture and this will dry out very quickly.
We print and clean thousands of models daily and go out of our way to make sure holes are cleaned out of powder. Even with this level of care, every so often, some parts do get by us with blocked holes. The powder should come loose if you give it a poke with a needle or something similar. Long thin holes can be a bit stubborn and in some cases designing in a ‘drain’ type hole half way along the part can aid in getting the powder out. In the studio we use modellers drill bits and airbrush needles which work great especially for smaller holes.
Keep it Clean!
Our prints are used for a variety of functions. In some cases the parts need to stay as white as possible. Oil and dirt can seep into the outer layer of the print but most dirt will come off with some soap and water. If the parts need to stay white and you are not treating it post print then our advice would be to keep it away from anything that will stain.
For machine parts most of our clients go for our carbon black finish so that wear and tear is not obvious.
Can the parts be Smoother?
Short answer – yes. We now have an industrial vibratory polisher on site so request that next time you order. It turns the finish from that of an Extra Strong Mint to a Softmint. If you’ve already received the part try some 400 grit wet and dry paper and make sure you refresh the water you use to avoid staining the part.
White is boring! We hear you… If you want to add some colour to your prints you can use water based acrylic paints or fabric dyes. For a professional paint finish, a filler primer will and some sanding will smooth the surface ready for paint.
If you want something special but don’t trust your own skill level why not try the team at Pango Studios who specialise in finishing 3D printed models.
Epoxy resin is the way to go. Araldite is the most common brand but there are cheaper alternatives out there if you have the time to look. Araldite is available in most hardware shops; alternatively you can pick it up in Halfords. It comes in a variety of strengths and has a varied set off time ranging from 1 to 20 minutes.
Super glue doesn’t work well at all. Even with the powdery layer removed, super glue seems to find its way into the outer most surface of the parts and does not adhere to the other object.
