What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

About

The goal of this Kickstarter project is to bring the near production functional prototype of our large 8 cubic feet All-in-one printer to production. This is a wonderful machine that was developed over the last two years pursuing the design goals of being large, accurate and reliable at a reasonable price. The design turned out to be so strong, that it was a natural fit for evolving it into an All-in-one CNC machine. So it is now not only a great 3D printer, but it also can be outfitted with a standard mount laser or various milling options with mounts you can print yourself. This makes it one of the most versatile yet affordable high quality All-in-one CNC machines today.  For a full list of printer specifications http://www.gobig3dprinters.com/specifications.

Another important but subtle feature that shouldn’t be over looked is that it uses open source software and firmware to make this machine open and hackable. It will come preconfigured with Repetier firmware for 3D printing with the laser and milling options already enabled. The machine will also be pre-wired for these options, so no modifications are necessary but you may need to make a custom mount for whatever tool you wish to use. We will have a couple of printable mounts that can be downloaded from our website for flex shaft and and direct mount Dremel mills.  The  firmware including the configuration file will be downloadable from our web site so you can configure it for whatever tool you wish to mount.

There is an outlet on the side of the machine to plug-in a 120V AC mill or any other device you wish to control. 12V DC power wiring for the laser or other device will go all the way to the terminal block on the back of the tool mount carriage. Power to both is controllable via G-code.

So what this means is that you can control and power any 120V AC or 12V DC tool you can mount on the carriage. This is powerful! With this flexibility, your imagination is the limit. You are not limited to just lasers and mills. If you want to download and print a syringe extruder from thingiverse.com and experiment with 3D printing clay or print a photo with icing on a cake, you can do that. If you want to laser etch some art and then mill a wooden frame for it, you can do that. With the open architecture and software, in full Maker spirit, your imagination really is the limit with this machine.

Please check out the various rewards we have to offer.  There are tee-shirts and vases of varying color and sizes.  All of the vases were printed on one of our large printers seen in the video and in the gallery.  Getting a vase is an excellent way to check out the quality of the prints first hand if you are thinking a buying a printer a little further in the future.  They also make beautiful and unique holiday gifts!

Risks and challenges

As Kickstarter projects go, this is a low risk one. The design of the machine has been extensively tested and is ready for production. But the manufacturing processes so far are all one-off, custom made in and out of house. The funds from this Kickstarter will be used to go from prototype manufacturing to more automated production manufacturing. This is a pretty straightforward step in bringing a product like this to market. None of the production processes that will be used on making this product are unusual or excessively expensive. Everything needed can be found at your local Tech Shop.

The processes to migrate from prototype to production will include but not necessarily be limited to the following:

1. Have a jig made for pressing the NEMA 17 motor mounts.
2. Buy a 4’ x 4’ mill for the hotend mount, motor mounts, acrylic frame, etc.
3. Have the leadscrew nuts injection molded in Delrin.
4. Contract a metal fabrication shop to make the back access panel with an EMS cage.
5. Migrate most of the printed parts to either CNC metal fabrication or injection molding.
6. Buy a plastic heat bender for the acrylic frame fabrication.
7. Build a frame assembly jig

By bringing some of these processes in house and migrating others to automated CNC manufacturing, the production time and labor will be dramatically reduced. Migrating the 3D printed parts to injection molding or CNC milling out of aluminum will also speed up production and make beautifully finished parts.

Another reason we anticipate the transition going from prototype to production will go smoothly is that all of the parts were designed with ease of manufacturing in mind. For example, the 3D printed parts that attach to the top of the X and Y axis carriages to connect the channel chains were designed to be CNC milled out of a sheet aluminum and be folded with a bending brake. 3D printing is great when you’re still developing the design, but twenty of these parts could be made with a CNC mill in the same time it takes to 3D print one.

This is where a lot of companies have trouble with their Kickstarter campaigns. They wait until it’s time to go to production and then they realize they need to redesign many of their components for production manufacturing. The design process takes longer than most people anticipate and can lead to long delays in the project. Rest assured that this will not happen to us. We will be ready to hit the ground running ready to start setting up the new production machinery and processes.
