A commitment to creating and knowledge sharing.

Our mission is to provide an uninhibited environment that promotes creativity and learning to any and all potential makers and hackers. We achieve this with our combination of collaborative work space, public classes, and the extensive knowledge base of our members.

The only Constant is Change

Arch Reactor is a constantly evolving organization, the tools-on-hand are ever changing and improving, driven by member initiatives.

Wood working

Power tools, hand tools, and specialty tools allow making just about anything out of wood

Metal working

Metal working capabilities expand and improve almost weekly as member make the tools they need

Textiles

From standard machines to industrial sewing that can handle denim and leather open many possibilities

3D printing

Several filament based 3D printers and resin printers are available, supporting projects up to 500mm3

Laser Engraving

With a 3ftx4ft cutting area our CO2 laser can cut and engrave large projects with ease

And more

Vinyl cutters, soldering, oscilloscopes, lapidary, and more!

Our 5000 ft2 reaction chamber contains a Shop full of equipment, a Lab to work on your projects, a Classroom to enrich your mind, and a Lounge where ideas can fuse together. Our space is a community workshop where members learn, collaborate, and bring ideas to life. Our members keep everything running, and our community is always working to improve the space.

Lab Area

The Lab area features a lot of table space for everyone to work on their projects in a low-dust environment. There are also many tools for working on electronics and other clean projects, including a soldering station, vinyl cutter, 3D printers, and an 80W laser cutter. There are shelves where members can keep a private tote, and an assortment of salvaged and donated parts available for anyone to use. 

Classroom

The classroom seats over 20 students in a clean and quiet space conducive to learning. It is not completely finished, but it is functional and we have been using it to hold classes. We currently have two large flat panel displays on the walls for presentations. We expect in the future to add a large projector screen, white boards, a wireless microphone system, and a live streaming camera all available for any class. 

Lounge

The lounge will be a cozy area for everyone to relax and socialize in. We currently have a fridge full of soda and a freezer with pizza, and we hope to soon have a full kitchenette. There are couches and comfy chairs, a MAME machine, and soon there will be a console gaming area as well.

Shop

Many of us urbanites don’t have garages to tinker in, which is why we have a fully featured shop in our space, including saws, vices, grinders, lathes, drill presses, planers, welders, kilns, forges and all the tools we need to create. Some tools are owned by the organization, but most are owned by our members and shared. Use of the shop is restricted to members, and you must always be trained before using a new tool.

“A co-op workshop for techies, tinkerers, and free thinkers.”
