About this project

3D printing and desktop fabrication have seen a boom in popularity in recent years, as more and more people are bringing their ideas to life. From the person who wants a little Snork for their desk to the parent that wants to give their child a prosthetic hand, everyone is starting to use 3D Printers. 

At Griffin 3D we saw a need for a high quality, low cost 3D printer that can be more accurate and produce objects faster than others on the market. That is why we created the Griffin Pro series of 3D Printers. A line of fast, reliable and super accurate 3D printers that can scale to fit your needs. 

Our Mission

We believe that 3D printing is for everyone. There are two things that one must keep in mind when using a 3D printer. First of all, consider your build volume- make sure you have the right size printer for your needs. Second of all, use your imagination! 3D printing is all about what you want to make; robots, prosthetic's, toys, figures, car parts, etc. It doesn't matter what you want to make as long as you are willing to use your imagination to make your ideas come to life. We want to provide you that opportunity to let your imagination change the world.

Who We Are

The founders of Griffin 3D, Doug, Ryan and Scott all met at Arch Reactor Hacker Space during a 3D Printer Meetup. After months of development, we decided to bring the Griffin Pro Series to the market and to show the world how great Delta printers are. We have worked long hours and late nights on the Griffin Pro Series and we hope that all our efforts shine through in the quality of our products.

What Is A Delta?

In the world of Fused Deposition Modeling (FDM) 3D printers there are two major categories: Cartesian's and Deltas. Cartesian style 3D printers are machines that move on the X and Y planes like your standard 2D paper printers, with a Z axis added in to allow for the third dimension of printing. While the setup for Cartesian's can vary from machine to machine, they all work in a very similar fashion. This type of 3D printer also uses hardened precision rods with linear bearings and acme lead screws moving captive nuts. Having all of these precision parts, means a higher base cost when building the machines. Also there are more parts that can have issues due to the need for precision.
Delta style 3D printers work much differently to achieve the same type of FDM printing. Delta style printers are triangular in shape with each axis using 1 corner of the triangle. Each axis has a Carrier that moves vertically along a piece of aluminum extrusion that is a part of the frame. Each Carrier uses rods to connect to an Effector at the center of the Delta style machine. As each carrier moves vertically at different heights, it causes the Effector to move in all directions needed to create a 3 dimensional print. 

The Griffin Pro Series

What sets the Griffin Pro series apart from other 3D printers is its ability to perform a semiautomatic calibration in under 3 minutes, giving you perfect prints with minimal hassle. Unlike others, our machines hold that calibration even when bumped or moved. By using state-of-the-art Force Sense Resistors and Optical End Stops, the Griffin Pro Series gains an accuracy of +/- 25 microns. That means parts are accurate to within the thickness of about a single human hair.

With Force Sensing Resistors and Optical Endstops for semi-auto calibration, we wanted to make sure that the print bed was strong enough to withstand tapping from semi auto calibration and the removal of prints. To reduce print bed damage on the Mini and Pro printers, we used something never before seen on 3D printers- Corning Gorilla Glass. The 2mm thick Gorilla Glass makes sure that it is very, very hard to crack or pit the print bed. Gorilla Glass is also tougher than standard borosilicate or single pane glass that many other 3D Printers use.

As we sought to make sure that we had smooth movements throughout all of our prints, we found that moving to motors with 400 step per revolution allowed us to create better quality prints while improving speed and accuracy. Combine that smooth and fast movement speed with our custom hobbed pulley, allowing for better retraction and extrusion and higher speeds.

After all of those upgrades, we had one last goal to take the Griffin Pro Series to the next level: Better Electronics. We wanted to skip the usual Arduino based controllers and go directly to state of the art ARM based controllers. This allows us to compute faster and run faster, and use motors with higher precision. With the Azteeg X5 Mini we got everything we wanted and more out of our electronics with its 32 bit ARM processor.

By using Smoothieware we can give users a simple interface for updating and modifying their firmware Along with the Azteeg X5, we are also working with Panucatt Device to outfit the Griffin Pro Series with the Viki 2 - a large, high quality LCD that works great with 32 bit electronics, and it isn't even on the makert yet!

Why We Need Your Help

With the Griffin Pro Series in the final stages of prototyping, our supply chain is setup and ready for our orders. All we need now is your help. Support the next stage in the evolution of 3D Printing by helping us with enough orders to bring all of our pricing down to its most affordable level. With your help, we can bring the Griffin Pro Series 3D Printers into your home, office, school or hackerspace.

Risks and challenges

There are always risks when creating something new and innovative. For our Griffin Pro Series, the single biggest risk is suppliers running out of products to supply us with. While we have alternative suppliers at the ready, we want to make sure to bring you the best product we can in a timely fashion. Alternative suppliers could possibly mean longer lead times on some products which would delay our shipping. We value your support and we will do everything we can to prevent this outcome.

FAQ

  • Our printers use 1.75mm filament.

    Last updated:
  • We plan on working on the heated beds before the end of the Kickstarter, however we cannot guarantee that they will be ready before then. The Force Sensing Resistors are still relatively new to 3d printing and they do not like heat, as such, heated beds are still experimental, and there is no precise timeline for when we will have a working system. However, these are open source printers and therefore there is nothing to stop people from doing it themselves even if we don't have them ready when the machines are shipped.

    Last updated:
  • The Griffin Pro printers will be shipping with the JHead Mark B-BV, We are continuing to test other options but this has been the most successful and reliable in all of our testing.

    Last updated:
  • The E3D V6 for 1.75mm filament is NOT an all metal hot end, it uses a PTFE liner to reduce the size to 1.75mm from 3mm. J-heads are well known to work well with a large range or plastics. It's not glamorous or trendy, but it works very well. We have explored several options and have experience with a multitude of hot ends. While we are looking at and testing other options, the JHead is still the most reliable that we have tested.

    Last updated:
  • We will have an updated picture of the extruder package with our next big update full of videos and pictures that will be coming out next week. The Extruder Kit comes with our custom hobbed pulley, the extruder bracket, an idler bearing, pneumatic fittings, a geared stepper motor and all of the nuts, screws and t-nuts needed to mount it all.

    Last updated:
  • We are using an Adafruit Trinket in our prototype machines and are in the process of creating a small board with pin outs that will allow the FSR's to connect more easily to it for easy and solderless assembly

    Last updated:
  • While our printer is capable of printing with ABS, there are technical limitations which are not limited to our printer. Due to the high shrinkage rate of ABS, it curls as it cools. As such, users are limited to about 1 inch across before deformation occurs. If a heated bed (which we hope to offer at a later date) is used then you will be able to print about 4 inches across before severe deformation occurs. Beyond 4 inches a purpose built printer with a heated chamber would be needed. These heated chambers can cost tens of thousands of dollars and is not something we will be offering.

    Again, this is a limitation of the plastic, not the printer.
