I have found many interesting products that have been made using 3d printers i find each one interesting for different reason such as the guitars because it is not a block of material they are more like webs and also with the second one they have changed the colour of the print, the city model interests me due to the amount of detail that the printer has given and lastly the gun because the printer has manufactured all of the working pieces and all that is needed after is the assembly and then it is ready to use
