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.
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
What Is A Delta?
The Griffin Pro Series
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.Learn about accountability on Kickstarter
Our printers use 1.75mm filament.
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.
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.
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.
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.
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
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.
