How to use our 3D Printing Service

So, you want to use our 3D Printing Service? 3D printing can be used for so many applications and since it’s a new technology, we thought we’d explain more about the process of using our 3D Printing Service. First, congratulations! You are thinking outside the box and finding new ways to turn your ideas into reality by using a 3D printing service! That’s the first step! But what’s the next step??? What’s Needed? Number One is that you need to have a digital 3D model of what you want printed. You can create this yourself in 3D modelling software, you can download designs from a number of websites, or you can get our designers at Kuunda 3D to design something for you. If you will be designing yourself, keep in mind that there are specific requirements for designing for 3D printing, like minimum wall thickness. Get in touch with us[…]

3D Printing No-Electricity Electronics

Researchers at the University of Washington are 3D printing no-electricity electronics parts to create devices that can transmit information over Wifi – no electricity or batteries required! If this sounds complicated, it is a little. They had to figure out how to transmit data in binary (zeros and ones) from a physical input (such as a push of a button, moving of a wind turbine etc).   The team 3D printed gears, switches, springs and the base parts in plastic, and then 3D printed the antenna and switch with conductive copper filament. “Our goal was to create something that just comes out of your 3D printer at home and can send useful information to other devices,” said co-lead author and UW electrical engineering doctoral student Vikram Iyer. “But the big challenge is how do you communicate wirelessly with WiFi using only plastic? That’s something that no one has been able to do[…]

3D Printed Architectural Models – Tudor Apartments in Mombasa

3D printed models are changing the way architects and property developers show off their designs and new buildings to their clients. For architects, 3D printed architectural models allow them to display details that are hard to grasp in digital renders or traditional old-school paper and cardboard models. For property developers, 3D models allow them to show their potential buyers how the development will look, from the overall placement on the property to the interior floor plan. For this model, we partnered with Urko Sanchez Architects to show off their fantastic Tudor Apartments by Swahili Gem. This apartment building is already built and occupied in Mombasa, Kenya, but its design was perfect to show what 3D printing architectural models makes possible. How we make 3D printed architectural models In order to 3D print, we need to have a 3D digital design. Architects use 3D modelling software to create the digital models[…]

Important: Store your filament properly!

3D printer users need to know how to store filament properly, especially in hot and humid climates like Dar es Salaam and Mombasa. If you don’t store your filament properly, you can easily lose the entire roll in just a few rainy days. Humidity causes poor prints We recently visited a customer who had been successfully printing with their Ultimaker printer, but the prints had then started to go down-hill – they became grainy and after a few layers the filament stopped flowing. We inspected the printer and found that the feeder was working fine, there were no filament tangles and the nozzle was not clogged. We asked how they had been storing the filament and it turned out they were leaving it on the printer, which led to it becoming brittle by absorbing humidity from the air (coast regions can easily reach over 70% humidity). When we bent the[…]

Pitching Kuunda 3D to Airbus

On September 26th, Kuunda 3D founder, Elizabeth Rogers, pitched our business model to Airbus in the Airbuz Bizlab #Africa4Future competition supported by Novato Africa. We took part in this pitch day as Airbus was specifically looking for African startups in the areas of: Unmanned Aerial Vehicles Satellite Operations and Imagery 3D printing Smart Sensors Artificial Intelligence The finalists included 8 Kenyan companies, 1 Ugandan, 1 Ethiopian and 1 from Sierra Leone. It was an inspirational day as all the startups are doing impactful work with innovative technologies. Unfortunately Kuunda 3D did not win the competition, but we were given great feedback on the pitch presentation and congratulations for already successfully operating in Tanzania and Kenya. A Kenyan company, Illuminum Greenhouses, won the competition which includes a trip to Airbus Bizlab headquarters in Europe for mentoring and access to investors. Congratulations for their success! Kuunda 3D is proud to be among East[…]

Advanced Materials for 3D Printing…Continued

Continuing on from our last post on Advanced Materials for 3D Printing in which we discussed the uses of Nylon, Polycarbonate and PVA, we’ve got more to share here on advanced 3D printer materials….. Flexible or TPU 95A Flexible materials & filament are used in a wide range of applications. It’s a rubber-like filament that comes in a range of flexibilities, or shore-hardness ratings. If it’s rated a 40 or 45 in shore hardness (like the Innofil3D Innoflex40/45), then it is more flexible than a higher shore hardness (like the Ultimaker TPU 95A). Really flexible filaments, like the Innoflex40, generally work better on a direct drive 3D printer system (with the filament feeder located right before the hotend, so the filament is basically pulled into the hotend, such as on the Tinkerine Ditto Pro) than on a Bowden tube system (with the filament feeder located at the back of the[…]

Advanced Materials for 3D Printing

Great advances have been made in the last few years with 3D printer materials (the filament, or ‘ink’ for 3D printers). Because of advanced 3D printer materials and technology, more materials and colours are now printable. We always recommend new users to start with PLA (poly acetic acid), as it’s easy to work with, safe for use anywhere and available in a wide range of colours. This maize-based bioplastic is the go-to material for 3D printer users, but there are now so many more options available in advanced 3d printer materials. Give them a try! Nylon (Polyamide) Nylon is an industrial-grade impact and abrasion resistant material that’s used in manufacturing. It is durable, strong, has good flexibility and low friction, and is corrosion resistant. As such, it’s great for tools, functional prototypes and end-use parts. High strength-to-weight ratio Low friction coefficient Resistance to alkalis and organic chemicals Available in black[…]

3D Printing Prosthetic Hands

Improving 3D Printed Prosthetic Hands in Tanzania Lake Victoria Disability Centre in Musoma, Tanzania, recently upgraded their 3D printer to an Ultimaker 2+ that they purchased from Kuunda 3D. The engineers and technicians at LVDC had been using a Prusa i3 Hephestos 3D printer that they assembled from a kit in Musoma. They contacted us to purchase an Ultimaker 2+ because they wanted to upgrade to a more reliable 3D printer from a local company. Because Kuunda 3D is based in Tanzania and Kenya, we are able to provide local support, including technical support, warranty extension and supply of spare parts. [wpvideo kxoxVFl8] In addition to the extra reliability of the Ultimaker 2+, the technicians are now able to print WAY faster than on their previous printer. What took 44 hours to print on the Hephestos printed in 10 hours on the Ultimaker 2+!  The team can print 4 times[…]

Saving the Go-Karting Day with 3D Printed Parts

A few weeks ago a client got in touch with us for an urgent request…there was a go-kart race coming up that weekend and a crucial piece of the go-kart was broken. They wanted to know if we could print them a replacement part in time for the race on Sunday. The client was able to provide us with a 3D printable 3D model (like a CAD file) on Friday evening, and we printed it on Saturday while we were giving a demo at the Gadget Shop, at Sea Cliff Village in Dar es Salaam. Unfortunately, half-way through the print, the power cut and we had to start again. We still had time though and their part was printed and ready for pick-up by 5pm 🙂 The piece fit perfectly and was used in the go-karting on Sunday! We printed this piece on an Ultimaker 2+, with 100% infill and[…]
