3D Printing for FIRST Teams (1 of 8)

Image
This is the first entry of an 8-part series. Each entry will be published Tuesday, so be sure to look each week for the next post! 3D Printing for FIRST Teams Authors: Kari Karwedsky, PTC , and Colm Prendergast, Mentor for FRC Team 1965 Many FIRST Tech Challenge and FIRST Robotics Competition teams now have access to a 3D printer thanks to the generous donations of suppliers, but now what do you do with it? To get started, it’s probably a good idea to just tinker with it making something like a pencil cup to get a feel for how the printer works. But after that, how do you decide what makes sense to print for your robot? In this blog series we’ll review a robot design (by FRC Team 1965) that has several components that were 3D printed. This robot was specifically built to test the capabilities of 3D printing techniques. We will then walk through the 3D printing workflow used. We will discuss guidelines for deciding which parts might be good parts to consider 3D printing for your...

Dean's Homework 2016

Image
Name  Date  Dean's Homework Assignment The assignment is for FIRST Tech Challenge teams to support their local FIRST  LEGO League Jr. Partner by forming, mentoring or otherwise supporting new FIRST  LEGO League Jr. Teams and Events. Why is this great news? This is great for FIRST LEGO League Jr. because  FIRST Tech Challenge team members are knowledgeable about FIRST , and can be  excellent role models for young students.   It is great for   FIRST Tech Challenge team members because it’s an excellent way to give back, do FTC Outreach,  be involved in their communities, recruit future team members, and grow their FIRST  community. What does it mean to you? FIRST will collect inquiries from  FIRST Tech Challenge teams on how they can help and send them to FIRST LEGO League Jr. Partners.  Please send us an email at deanshw@firstinspires.org  to find more information about the FIRST LEGO League Jr. Partner in your region o...

3D Printing for FIRST Teams Authors: Kari Karwedsky, PTC , and Colm Prendergast, Mentor for FIRST Robotics Competition Team 1965 3D Printing Work Flow The 3D Printing Work Flow that we use is composed of 7 steps.   Step 1: Design your part using PTC Creo. Step 2: Export Model from PTC Creo in .stl format. Step 3: Prepare Model and Generate g-code file (or equivalent) for the printer. Step 4: Prepare and Level the 3D Printer Build Plate. Step 5: Load printer filament. Step 6: Print Model. Step 7: Clean up printed model. In this blog post, we will look more closely at Steps 5 and 6. 3D Printing Step 5: Load printer filament. Loading the Printer Filament is the last step to be completed prior to printing. Most 3D printers use spools of filament that are un-rolled as the filament is consumed. In our case we use 1kg roles of PLA filament. For this project we will use a roll of MakerBot “True Red” PLA filament with a 1.75mm diameter.  MakerBot “True Red” PLA filament  PLA is a...
