We specialise in making customised technical and sidemount dive equipment, using high quality performance materials such as titanium and carbon fibre composites.

We also believe strongly that you should get what you pay for, therefore quality, innovative design and performance come first.
We are a small team of technical divers, instructors and technologists who are passionate about diving and using innovative technology and design to improve and enhance the diving experience.
Innovation
Here at Nammu-Tech we are always to trying to improve. This philosophy is applied to the products we design and build, to new and original ideas we try to turn into reality and to our interactions with our customers and the diving industry as a whole.

‘How do we make this better’ has been our mantra from the start, and seems to be paying off. We take pride in making designs practical, ergonomic and cost effective for both ourselves and our customers.
CUSTOM PARTS
Recently we have been receiving more and more requests for help to design custom equipment for various applications in the scuba diving industry, and increasingly from other sectors.

We have found that our additive manufacturing methods are very much compatible with the needs of smaller companies, as we are able to quickly produce and (or) design the same products on smaller scales, for a more competitive price. This requires significantly lower capital outlay than a more classic injection moulding and production scenario.
all the materials mentioned above are incorporated into our 3D printed products. Some of the materials we use incorporate chopped strands of carbon fibre, which creates a significantly more resistant material.

Additionally, filaments of carbon fibre, fibreglass and kevlar can be incorporated into the product during the print.
This allows us to reinforce fragile areas, and create shapes that otherwise might be impossible.

CARBON FIBRE
Carbon fibre is a thin filament made up of carbon atoms organised into a crystalline structure. Because of its very high stiffness and strength it is widely used in the aerospace and automotive industries.

Carbon fibre has a flexural strength of 470 MPa (68 ksi) which is 20% higher than the yield strength of 6061 aluminum. Its tensile strength is 700 MPa (102 ksi), more than twice the ultimate tensile strength of aluminum. To learn more about carbon fibre material properties see below.
KEVLAR
Kevlar is eight times more impact resistant than ABS while remaining 15–20% lighter than our other reinforcement fibres.
TITANIUM
Because titanium alloys have high tensile strength to density ratio, high corrosion resistance, fatigue resistance, high crack resistance and ability to withstand moderately high temperatures without creeping, they are used in aircraft, armour plating, naval ships, spacecraft, and missiles.

For these applications, titanium is alloyed with aluminium, zirconium, nickel, vanadium and other elements to manufacture a variety of components including critical structural parts, fire walls, landing gear, exhaust ducts (helicopters), and hydraulic systems.
In fact, about two thirds of all titanium metal produced is used in aircraft engines and frames. The titanium 6AL-4V alloy accounts for almost 50% of all alloys used in aircraft applications.

As can be seen from above, titanium, whilst not as strong as stainless steel, given its density and weight it makes for a very practical material to use within the dive industry.
