3D scanning and printingfrom here you can see what we did on the group assignment
- 1.- design and 3D print an object (small, few cm3, limited by printer time)
that could not be made subtractively
- About the tweezers
- About the modeling software
- About the slicer
- About scanner
- About the hinge
- Links and references
for the individual asssignment i choose an easy replaceble tweezer using polylactic acid PLA as it is the most common and cheap printable material.
as i became comforable enough with the smd soldering process. i struggle a lot with getting my hand on a cheap tweezer that can help me to hold the resistors and another smd components while i solder them. among other issues.
maybe somebody will say that die cut is a sustractive process (and it may be right if only uses die cut to manufacture a product) but the entire process of the tweezer includes spot welding wich i think it may count as an aditive process.
So i modeled a pair of tweezers for smd components using solidworks
i used some basic geometrical constraints and dimensions considering the diameter of the extrusor wich is about 0.4 mm using expresions on solidworks
then i imported into ultimaker's slicer software named cura
HERE you can download the most recent version of ultimaker's cura
where i twitched a little the default presettings to rush it a little, i set the layer height to 0.2 mm the speed to 60 mm/s and 10% infill.In the future i'd like to experiment with the formalbs flexible resin to make a 3 fingered gripper using the same principle of compliant mecanisms
after setting the parameters i clicked on the slicer button and saved it as G-codehere you can download my G-code
then set the printer making the tweezer
For this part of the assignment i used the microsoft kinect and usb adapter to 3D a printed part that i had near and made a video tutorial out it however i previously installed the kinect driver and a software called skanect that has a really nice freemium version. here you can go to download the driver i used on windows 10
