Kidz Track Info (Tues-Fri)

Human 3D Printer:  a social STEM learning experiment.  8-9AM (Tues-Thurs)

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 non-disruptive children of any age.

A Kid’s World of 3D printing.  9-10AM

This session is targeted for children. All ages of children 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. We will also go over basics of how to make models and different types of CAD apps including some that are free or more kid friendly. We’ll also discuss where to get free model and where to print them. This is the basic overview. Kids should start with this session before using the lab or doing the follow-up modeling course.

A Kid’s introduction to 3D Modeling.  10AM-12PM

This second session we will work with a fully-featured CAD application called Rhino3d and walk 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. The session is probably most appropriate for children over 8 but all are welcome based on the child’s capabilities and ability to enjoy. The goal of the session will be to create up to to two basic things- a cup, and a keychain.

Less confident or younger kids are welcome to pair up with parents or siblings and just watch the parent/sibling. Kids that complete the kid projects without issue are welcome in the adult walk-through lab as they will be making slightly more advanced models that are different.

PLEASE NOTE: We have a fairly large number of printers in the lab so our kids can possibly print items they make in class. We will be able to produce a screen render of any models kids would like, and we make our best efforts to print at least one model per student, based on demand.

Adults Track Info (Tues-Thurs)

From idea to physical series: A basic overview of the world of CAD and 3D printing.  1-2PM

This session will 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. 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 session is for you!

From idea to physical: A demo of how to make CAD models in Rhino3d.  2-4PM

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 the UI and how Rhino uses basic curves and shapes to create more advanced geometry, and create up to three basic models: a goblet, a challenge coin, and a spaceship model.

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 slightly more advanced models that are different.

Bonus Track Info

From idea to physical series: Additional Castle project walk-through Rhino project.  4-5PM Tues-Thurs (NEW for 2020)

Can’t get enough model building? Want to make something more advanced than your basic cups/keychains/challenge coins? We’ve noticed we have some repeat students each year on our kids track that just love to build models, and we’ve also run several years of our introductory track for adults. We wanted to add some additional options to expand model building skills for those who have been through our previous sessions.

We are running a few additional Rhino model-building walk-through sessions, welcome to anyone (kids or adults) who have gone through the regular introductory sessions. These run after the adult sessions in the afternoon- 4-5pm -and may extend into open lab time if audience interest and project is there.

We will work through making a fantasy castle model suitable for 3D printing, using a variety of model techniques! While this session will repeat, we won’t be using a fixed template for our castles- so attendees are welcome to come to multiple castle sessions and make different castles (or continue working on a super elaborate one!).

PLEASE NOTE: This is a session that is likely have both kid and adult attendees, and the session assumes basic familiarity with the Rhino interface. If your child has attended the introductory class and is looking for a chance to make something more complex, they are welcome in this class. It is likely best for High School aged teens or late junior high aged students, but any kid that has completed the introductory class without issue and is able to follow a slightly faster paced class may also attend.

“How would you print that?” interactive panel.  5-6PM Wed-Thurs (NEW for 2020)

We have a wealth of different perspectives reflected with our 3D printing room staff- including tinkering hobbyists, hardcore makers, and even that of using multiple printer types repeatably in a small business setting.  We thought it would be fun to share these various perspectives on how we approach 3D printing projects with all of you. We are debuting our Lab staff/audience interactive panel called “How would you print that!” We will start with some basic projects, work up to more advanced ones, and even talk through some audience projects. We’ll discuss slicer settings and supports, materials, printer types, SLA vs. FDM, temp settings, and even the economics of printing models. We are likely to cover different projects each interactive-panel session. Feel free to stop in for more than one!

PLEASE NOTE: The panel will be fast paced using more advanced printer lingo, so it’s recommended you either have some familiarity with 3D printing, or take one of our introductory classes. If your child has 3D printing or maker experience, or has taken the other classes and wants to learn more about 3D printing, they are welcome in this class. It is likely best for High School aged teens or late junior high aged students but any kid that has completed the introductory class without issue and is able to follow a faster paced technical conversation may also attend.
