After coming back from the RAPID conference<\/a>\u00a0I kept thinking about building a custom bike by printing the lugs which hold the bike frame tubes together. \u00a0The concept is not new. \u00a0Here is one builder from Australia<\/a> who has led the way in creating titanium lugged bikes and another artist, Ralf Holleis, who has 3D printed titanium to create a real beauty<\/a>.<\/p>\n

I thought I would do some experimentation in Fusion and share the process. \u00a0Maybe some new capabilities you would like to try out.<\/p>\n

Tubes are held together with lugs<\/strong><\/p>\n

I started with an attached canvas that had the basic layout. \u00a0In order to get the size of the canvas correct I selected the canvas in the browser and using the right mouse button to display the options. \u00a0Calibrate will allow me to define two points that will scale the canvas properly. \u00a0Then I created a sketch for the main tubes. \u00a0The Model workspace has a Pipe command that allowed me to create the basic tubes. \u00a0I created one set for the tubes and another set which was one millimeter larger for the lugs. \u00a0I combined these lug pieces together with Combine and filleted the intersection. \u00a0That was the base solid lug I would use to experiment with. \u00a0I created several copies so I could try different approaches.<\/p>\n

Chopping it up<\/strong><\/p>\n

I wanted to create some recesses in the lugs where I could feature some patterned designs. \u00a0This could be approached by projecting sketch curves from a view but I wanted a result where the recess walls were dynamic. \u00a0I used T-Spline bodys as 3D cutting surfaces. \u00a0The lug body was in one component and the T-Spline bodies were in another. \u00a0I applied appearance colors to each component to easily distinguish where the cut lines would be as I modeled the T-Spline with Edit Form.<\/p>\n
