3d Printing and Modeling @ CodeMash

CodeMash is once again happy to announce 3d Printing and Modeling! If you have ever wanted to get some hands on experience with these technologies, this will be a great opportunity. Space will be limited to the size of the rooms, but registration is not required. We are running tracks for both Adults and Kidz- see below for more information. A special thanks to Brian and Elizabeth Carnes for coordinating these activities.

Logistics Info

Printing your Ideas in 3D: A basic overview of the world of CAD and 3D printing.  1 to 2PM

This session will tour the maker lab, and talk about the exciting world of 3D printing with a bit of the history of the technology. We will look at the lab’s printers as well as models made on them. We’ll then cover choosing a CAD app and will briefly cover using curated 3D printer object libraries and different CAD apps that might be more appropriate to different types of projects. We will also cover different types of 3d printers as well as advantages and disadvantages of 3d printing services. After this session you’ll have the starting point on how to make models, where to get them if the model already exists, and where to print them.  We will finish the hour with a basic walk through of the process of planning a model, a very quick view of Rhino3d, how to convert to a stereolithography file (don’t worry, we will explain what that is!) and slice and finally print on a 3D printer. If you have heard of the exciting world of CAD and 3D printing but have never tried it or would like a basic overview this lab is for you!

From idea to physical: A demo of how to make a CAD model, slice it and print   2 to 4PM

This lab is intended to be a fast-paced technology walk-through of the process of creating a 3D printed object.  We will focus in on the process of using CAD to create our model with a NURBS modeler called Rhino3D and will walk through and create up to three basic models: a goblet, a challenge coin, and a spaceship model. We will also look at some completed models that were created for 3d printing and discuss what one should consider when making a successful printable model.

We will discuss scaling, splitting, tolerances and other final model steps in Rhino3D, as well as converting to a stereo lithography file the slicer program (Cura) can read. We’ll discuss the various settings in CURA and how to set up the G-CODE file that the printer will use.

High School aged teens or late junior high aged students may also attend adult sessions. Additionally, kids that complete all three kid projects in the morning sessions without issue are welcome in this lab as well as we will be making more slightly advanced models that are different.

CAD and 3D printing open lab:  4PM till dinner (varies)

This lab will allow you to use our equipment/software to build a model or prep one for printing. While our staff is available to assist, we are assuming your either are a self starter who has run through our introductory labs and wants to get your hands dirty, or have the basic background to use the technology in the lab.

Human 3D Printer:  a social STEM learning experiment 8-9AM

After a brief overview where we explain what the teams will do, we will be dividing into 3 teams.  A CAD team, a SLICER team, and a 3D printer team.  The teams will try to manually replicate with the team each piece of the 3D object development and replication process!  The CAD team will model the shape on graph paper. The Slicer team will figure out how to build the model and convert it to numbered “human gcode” instructions on 3X5 cards and the 3Dprinter team will try to execute those instructions on a grid representing a printer bed with a 3D doodler hand held extrusion pen! We’ll start by doing 2D shapes and as the teams get going we’ll try to make a basic 3D shape! This session hopes to explain how the process works at a basic level. This is an experiment involving discovery and teamwork and is probably most appropriate for children with basic measurement and writing skills although we will try to accommodate children that are not disruptive of any age.

A Kid’s World of 3D printing   9-10AM

This session is targeted for children. All ages are welcome with a responsible adult. We will tour the maker lab and talk about the exciting world of 3D printing. we will look at the printers as well as models made on them and pass around lots of things, and go over basics of how to make models,  different types of CAD apps including some that are free or more kid friendly. We’ll also discuss where to get free models, and where to print them. This is the basic overview. Kids should start want to start with this session before using the lab or doing the follow up modeling course.

A Kid’s introduction to 3D Modeling 10AM-11AM

This second hour session we will attempt to walk the attendees through the process of building a basic model from geometric shapes. We will explain the XYZ coordinate system, and what the different views are for. We will also spend some time playing with the transform functions.  This session is best for kids with basic skills in measurement, elementary level geometry, and basic computer skills.  Probably most appropriate for children over 8 but all are welcome based on your child’s capabilities and ability to enjoy. The goal of the session will be creating 3 basic things, – a cup, a keychain, and a toy house.

We will be doing this on the big screen and those at CAD stations or their own PC are welcome to follow along and make their own versions! (software requires PC/MAC, there is no Chromebook version, but we should have lab PC’s this year) We will encourage teaming up kids on PC’s so less confident or younger kids are welcome to pair up and just watch, but can still collaborate.  Kids that complete all three kid projects without issue are welcome in the adult walkthrough lab as they will be making more slightly advanced models that are different.

PLEASE NOTE: A kids lab will follow morning sessions where kids can possibly print items or make others. There is also open lab in the late afternoon. We will be able to produce screen renders of all models kids would like to, and can print possibly one model per kid depending on demand.

Kids Lab 11AM-12PM:

A kids lab will follow morning sessions where kids can work on their models some more or possibly print items or make others. We will be able to produce screen renders of all models, and can print possibly 1 model per kid depending on demand. If extra lab time is needed the printer side of the lab is open throughout the day and kids that have completed the other sessions are also welcome in the open lab slots.
