3D printed in pure brass in its natural state with a slightly rough antique finish.
Product Description
The Sunwayman V10R Ti's heatsink, being made of titanium, doesn't act as a very good thermal conductor and other materials like brass or silver would do a superior job and 3D printing can help create such upgraded parts.

I therefore present my Finned Heatsink, designed to replace the stock heatsink on Sunwayman; V10R, V10R Ti and V10R ti+ flashlight models.
Unfortunately due to resolution limitations in 3D printing, the two threads (1mm pitch) cannot be printed and need to be machined. O-ring channel re-working, re-facing the top and bottom surfaces to ensure that they are flat and smooth as well as a good outer surface polish are required to make the heatsink ready for installation.

The three possible material options are brass, bronze and silver.
However the Bronze material (90% copper, 10% tin) has quite a pore thermal transfer rate and should be avoided for use as a heatsink material.
The brass material (80% copper, 15% zinc, 5% tin) will be a marked improvement over the stock titanium heatsink but not the aluminium version. The sterling silver material (92.5% silver, 7.5% copper) is one of the best metals for thermal transfer (pure silver being the best) and would make an excellent heatsink and a true performance upgrade from the aluminium stock part.

However, apart from silver, it would probably be easier to make a brass heatsink from scratch, than to do the required machining to the printed version, especially considering a lathe would be needed in either case.
Also working in brass is generally much easier than working with titanium.

I suppose in conclusion these printed heatsinks aren't a particularly good idea but at least it's been proven to be possible.

There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page.
