Calculus Bikes Posted August 11, 2017 Share Topology optimised, 3D Printed, Titanium bike. Look at the Bottom Bracket on this frame. But imagine the whole frame is designed and built in one piece without weld seams... We are busy developing the technology to be able to do this, still some way to go but we will get there soon. We are developing the machine to produce aerospace parts, but nothing prevents me from printing a new bike frame during the shakedown of the machine at full build volume Hi, are you at CSIR working on their laser sintering? We were there a couple of weeks ago investigating the possibility of using Ti lugs for our carbon bikes. Impressive stuff! Link to comment Share on other sites More sharing options...
Calculus Bikes Posted August 11, 2017 Share loving it Sent from my SM-G935F using TapatalkSuch a nice bike, just too bad the water bottle spoils the picture. I am assuming someone with a bike like yours picked it up next to the road and will dispose responsibly. Link to comment Share on other sites More sharing options...

Impressive stuff!Jip, that's us. Carte Blanche recorded some footage for a feature they are going to do on our project, it should air on Sunday the 20th of Aug or thereabouts. It should give you more insight into the tech and the effort that goes into developing the process. Link to comment Share on other sites More sharing options...
BattleScar Posted August 11, 2017 Share Since you ask so nicely. . . . one more thing. (But this is nitpicking) Many manufacturers make use of a flat-bar in the beginning of the drive-side chain-stay at the BB. Like the Kona Raijin or this Lynskey.And while I understand 110% why they do it, wheel and chain-ring clearance, it makes the visual symmetry of the frame ugly. http://blogimg.goo.ne.jp/user_image/09/63/00bf8e02605338f85114a9e3dbb24800.jpghttp://d2ydh70d4b5xgv.cloudfront.net/images/e/6/lynskey-ridgeline-29-titanium-mountain-bike-hardtail-frame-size-small-68mm-bb-0649fa10ca49c071831905df0a4b5634.jpg Rather keep the chain-stays round tubes like on the Salsa Fargo Ti or this version of the Vassago Optimus Ti. Visually it just looks more balanced and smart. (But that is just my opinion) http://salsacycles.com/files/bikes/_carousel_thumbnail/FM1722-fargo_640x360px.jpghttp://www.tirides.com/wp/wp-content/uploads/2010/07/optimus.jpghttp://forums.mtbr.com/attachments/29er-bikes/776028d1361985523-just-got-see-new-vassago-ti-bike-optimus-bb.jpghttp://www.vassagocycles.com/picture/bbshell-sq.jpg?pictureId=17521382And those TIG welds Link to comment Share on other sites More sharing options...

Christie Posted August 12, 2017 Share Topology optimised, 3D Printed, Titanium bike. Look at the Bottom Bracket on this frame. But imagine the whole frame is designed and built in one piece without weld seams... Imo the best application would be to use 3d printing to make ribs etc on the inside to make tubes that would not be otherwise possible.For a frame, 3d printed lugs and tubes would be awesome. A whole frame in one go would be intdresting too, if cooling and support while printing can be controlled. (It would need some artistic input: see attached crank - impressive engineering, but not pretty enough for a lot of sales) Link to comment Share on other sites More sharing options...

Economic considerations are also difficult to justify for mass market roll out. At around R6500 per kilogram for your base material cost it becomes a fairly expensive exercise. But then again, I see 2nd hand bikes selling in the classifieds for R125k, so there will be somebody that will buy it, just not the average cyclist.

Simon Kolin Posted August 12, 2017 Share Please, please make sure you use a T47 Bottom Bracket. None of the Press-Fit nonsense. Link to comment Share on other sites More sharing options...

I understand they launched a South African Sattelite a couple of month back. (Wow, we are WAAAY off topic. Let's get back to the bikes) Link to comment Share on other sites More sharing options...
