2-sided 3D student project

[Mick S]

A couple of my students working on a 2-sided 3D file of a 1/2 scale prototype for a chair leg.

I already like them, not settling for the easy and all that. Will you be posting the end result?

[Mick S]

Yes, I will. John is an incredibly talented traditional woodworker, and a very intelligent guy. This course has convinced him of the need to invest in a CNC router to accommodate his imagination.

That's something I have only done one time but it was on a piece much smaller than that.  Do you have a photo of the finished chair?

Btw, every time I lean over from the side like that I get grease on my shirt.  Is your machine protected in some fashion so that doesn't happen?

Long story short, I've been absent the last 6 months or so. New machine at work, new capabilities, new material to work with, trip to Canada for training, etc. etc. BUT! I have something relevant to this conversation!

This is my first attempt at a 2 sided flip cut

It is EPS foam, also known as Expanded Polystyrene. Most commonly found as a packing material to secure objects in boxes.

I also have the capability to spray it with some really nasty stuff that essentially is a 2 part resin that cures in about 30 seconds... I hit this thing with a hammer and not a scratch, dent, or ding.

I'll post some other stuff I've made these last 6-8 months if there's any interest.

That's really cool!  How did you hold the piece when you flipped it?  I assume by the block remaining but photos would be good.

Double sided tape on the waste material adhered directly to the bed, Gaffer tape on the sides to hold it down to the bed as well.(A bit overkill) and a scribed line on the bed with a pencil for registration. Being that the media I'm using is foam, it is light, cuts really easily and doesn't need a lot to hold it down. Had a bit of an "oh no" moment when I realized I had my program start zero about an inch too far in for the Y axis and almost had no support material on the top edge.

hese projects often involve a multidisciplinary approach, combining science, technology, and creative design. Students delve into research, utilize computer-aided design tools, and employ hands-on craftsmanship to bring their concepts to life. It's a testament to students' ability to think critically and execute complex ideas. For those seeking guidance or professional assistance, platforms like https://essays.edubirdie.com/buy-essay offer support and resources, ensuring students can excel in both their creative and academic pursuits. Whether it's architectural models, interactive displays, or engineering prototypes, 2-sided 3D projects display the blend of technical prowess and artistic vision.

This is very cool!
