CLASS – TECHNOLOGY, 3D Printing

SOFTWARE: Rhino 6, Voxelizer, Polygon, Polulu Master Control

MATERIAL: PLA & ABS 1.75 mm, bolts, screws

MACHINE: Z-Morph, Picaso Designer 250 Pro, Raise 3D

CHALLENGES: To make a 3D-Printed thing


TASK / PREPARATION

The task sounded quite simple: create something 3D-Printed. The teacher suggested making this robot for extra credits. I accepted the challenge.

The robot and all the files I took from the Instructables: https://www.instructables.com/id/EEZYbotARM-Mk2-3D-Printed-Robot/

DESIGN / PRINTING / ASSEMBLING

I transfered all the .STL files into .gcode and Polygon files to use two 3D printers, that we have in lab.

Unfortunatelly, something went wrong with Picaso Designer, that is why there was only one printer left.

I coninued printing all the parts on Z-Morph. There was a problem with the quality, that is why I got really easy-to-break details.

Low-quality deatil of the base.

The time of printing also was not so good for the details, that is why I had to print them in other places by ABS.

ABS-printed details.

ASSEMBLING / CHECK

After all parts printed, I started assembling all the details together. On the photo of ABS-printed details you can see the assembled base.

Assembling the robot

In 2 hours the Arm was assembled.

The next problem was controlling the servos.

I am using Pololu Mini Controller, that needs the outer power supply to have enough voltage to move all 4 servos.

RESULTS / REFLECTION

It was a nice challenge for me and the quality of parts, their brakings did not stop me. I went to different places to reprint the needed details, servos.

Total expendutre on the project: 5000 rubles (including servos, Pololu and 3D-printing).

It is not easy to control the robot with Pololu application. I am going to write an app to control it by the phone via Bluetooth. Also, it is possible to make it work with Arduino.

As an overall result, I have a robot-arm and knowledge of 3D Printing by different printers, connecting the servos and some coding.

Class: Technology, 3d printing Software: Autocad 2018, 3ds max, Ultimaker Cura Materials: pla 3mm Challenges:
  • project model for laser 3d printing
  • learn how to work with 3d printer and software for it
  • create part for fixing main model for city project class

IDEA

I needed main axis of rotation for model at city project class. This axis had to be very small size, less then inner diametr of bearing, insight which I put my axis – 5 mm. 3D printer was the only appropriate machine for such task.

Design project

First of all 3d model in 3ds max was created. Then I put this model into Ultimaker Cura and set preferences for printing.  There is option in Ultimaker Cura  to use support or not to use ( but you can’t tune support) and to set the print density.

FINAL MODEL

The project of Smart Cube started from the form exploration.
