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[…]
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[…]
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[…]
Ultimaker has just revealed the winners of their global Ultimaker education challenge, and we are proud to announce that the International School of Moshi, Arusha Campus is the winner of the East African region! The school has been awarded an Ultimaker 2+ to carry out a student project, led by Design & Technology teacher Paula Elsley, that is intended to develop skills in technology, engineering, science and math. Students will use 3D design and printing to develop a better solution to farming methods in Tanzania. Their objective will be to design and create a seed planter that reduces the burden on farmers and will instead be attached to the back of a cow. The planter will disperse seeds along a field as the cow moves. We are happy to have been able to help ISM implement this innovative project and wish Paula and her students the best of luck in[…]
In November 2016, a team from Kuunda 3D Tanzania took our Ultimaker 2Go 3D printer on an adventure into rural Tanzania. There were several goals of this trip: 1) test whether a 3D printer could be used in a rural village with intermittent electricity, dust, and no computers 2) test whether it’s possible to teach and demo the concept of 3D design and printing to average villagers and 3) gather ideas for new models and designs that could be printed to benefit village life. Our team (Co-founder – Elizabeth Rogers and Marketer/Translator/Photographer/Driver – Kayvan Somani) headed to Kahe Town, located in the plains of Mt Kilimanjaro in northern Tanzania. As Kuunda 3D is based in Dar es Salaam, we had to drive over 500 km to reach the village. Unfortunately, we had a number of car breakdowns along the way, ranging from tire punctures to a radiator cover exploding,[…]
With the recent launch of the Ultimaker 3, a totally updated version of Cura has been released. This new version of the software is optimized for Ultimaker 3, but can still be used for other UM printers. Cura 2.3 contains pre-saved materials profiles that are optimized for use with Ultimaker filament. This takes much of the guess work and optimization time out of 3D printing. It also contains lots of new features, and one of our favourites is the gradual infill which allows you to start off with very little infill and end with more (to give you good internal support for a roof, but using as little extra filament as possible). Check out all the features on the Ultimaker page here!
This post is from one of our customers, Gowtham, who is using special filaments to make some amazing products, like mobile phone cases. Enjoy and thanks to Gowtham for sharing his experience & thoughts with us! 3D Printing in General: I did not have any previous experience 3D printing apart from taking an introduction class a couple of months ago and reading journals and websites about the development of the industry. My decision to buy the 3D printer was purely entrepreneurial. I wanted to make a change in the everyday market with 3D printing for the public. I’ve been printing art, jewelry, accessories for electronic items. I’ve also made quite a start in the medical industry too. I can say 3D printing is like an addiction. As you get more and more perfect prints I feel like I should keep on printing and trying with new and different combinations and[…]
A few weeks ago a piece from our luku (pre-paid electricity meter) machine broke, so we decided to put our 3D design skills to the test by designing a new one instead of going through the tedious process of replacing the entire machine. Using a pair of digital calipers and 123D Design software, it only took five iterations to re-create the piece. We ran into some issues trying to get the piece to lock down perfectly into the ridges at the top and bottom of the slot. However, with some experimentation we were able to design a piece that fit perfectly into the slot and was strong enough to hold the batteries down. Watching the piece sit perfectly inside the machine was a pretty satisfying feeling after all that hard work! 3D printing allows you to conveniently prototype products and produce multiple iterations quickly. Let us know if you have[…]
Next week Kuunda 3D will be teaching a 3D Printing and Design course at Nafasi Art Space in collaboration with ReFab Dar. The class is almost full, but there is still space for a few more participants. We are looking for female artists, in particular, to take part. If you are a designer, artist, performer or a maker, please contact Nafasi to register.
Many students around Dar es Salaam are on holiday during the months of June and July. For parents looking for something educational and fun for their children to do, we are offering a holiday camp during the week of July 4 – 8th for children age 9 and up. Students will have fun seeing a 3D printer in action, getting exposure to this amazing technology, learning how to design their own models, and then having their own designs printed to take home. Get the flyer here. CAMP DETAILS: July 4 – 8 Dar International Academy campus, Masaki $70 USD for 5 sessions of 2 hours each, includes printed objects Morning session: 9-11am Afternoon session: 2-4pm Contact us at firstname.lastname@example.org or 0754654548 to register. Spots are limited to 18 per session so register quickly.
