Welcome to the world of HD^2. Why the ^2? It stands for High Definition AND Heavy Duty and it embodies the personality of this printer, from the oversized base to the professionally designed interworking parts.
If you want a printer that prints as good as it looks, then the revolutionary design of the HD^2 is for you. I guess the only question you need to ask yourself is do you want to attend our exclusive Launch Party in New York City? Receive your HD^2 before ANYone else, meet the creators, and also included is one-on-one instructions and help on setup of your brand new HD^2!! Or do you want to simply wait and receive yours on your doorstep?
Above is the HD^2, which comes with everything seen in the picture. If you choose to have yours assembled, simply remove it from the box, plug the USB cable into your computer and print. No need to add extras (although you can add them later), just open the box and start printing once open source software configuration is complete! Perhaps if you're adventurous and enjoy electronics like us, you can assemble your own with easy-to-follow electronic directions. Not only do you get an electronic set of instructions, you will also get access to videos which explain the finer points of assembling your very own HD^2!
No matter which you choose, you will be greeted with the sight of cold, hard aluminum frame combined with perfectly sculpted custom engineered connections. No low quality parts on this printer, only the highest quality parts are used to ensure absolute reliability and consistency in prints. From the base to the top plate of the HD^2, everything screams HEAVY DUTY!
With its 200mm x 200mm x 225mm (roughly 7.8"x7.8"x8.8") build envelope, the HD^2 is more efficient and more reliable than most 3d printers currently available to the consumer today. This is in part due to the HD^2's direct-drive extruder, but also to its unique intuitive 3-point leveling system. With the all new 3-point leveling system, leveling the heated build plate is much quicker and easier than any of the other 3d printers available from other companies.
The proof is in the pudding, persay. Its simple to see that adjusting 3 points is easier than adjusting the standard 4 point leveling system. (and if you have ever owned a 4-point leveling system, or currently do own one, you know EXACTLY what I am speaking of). Bottom line: 3 point leveling produces unprecedented accuracy and reliability in the function of the heated bed.
While the HD^2 is mathematically theoretically capable of printing up to a 25 micron resolution, it is suggested that most prints be completed at the ~100 micron resolution. The test print in the video we have included was printed at 100 micron resolution (normal settings), which is the maximum resolution offered by many other printers on the market.
The reason for this is the time it takes to print something with fine detail resolution will be four times that of a typical print. However if print time is not an issue, it is notable that the high resolution print will have four times as many layers.
This high resolution is attributed to the upgraded hardware on the HD^2:
With these all included standard, the HD^2 has the stability and the hardware to produce stunning prints up to 25 micron**. Check out our printer's primary assets, as compared to the current competition available on the market right now:
** 25 micron maximum resolution has been theoretically mathematically calculated using the actual specifications of the hardware included with the HD^2. Although it is possible to achieve this high FFF resolution with the hardware used on the HD^2, we have currently not tested this resolution on the HD^2. However, once funded we will be to test print at 25 micron resolution due to a current lack of funding for filament and calibration supplies.
Each of the HD^2s will be hand-made right here in the United States, using the expertise and technical know-how of the creators. Before shipping, each printer will be subjected to a 60 point inspection as well as a test of the electronics included. This verifies that every single item that leaves our warehouse facility will be to the exact specifications that we desire and have promised to you, the Kickstarter community. We stand behind our quality control, and plan on setting up a public forum on our website for HD^2 owners. Should they encounter any issues or have technical questions involving usage of the printer, we (and other owners) will be there to help you!
We believe that high quality 3d printing should not cost tens of thousands of dollars, and we believe our project will help to do just that: bring a 3d printer capable of high definition prints into homes and offices everywhere!!
Currently our prototype model is capable of printing through dual extruders, but software and financial limitations have made it so that we are unable to produce dual extrusion with the firmware which we are using at this time. Once funded, we will be able to focus entirely on the issue for dual extrusion, through both firmware and software troubleshooting. Although it is a functional prototype, it does not highlight all the potential of the printer. This is where the funding helps a LOT. We would use part of the funding money to enhance our research and development in order to be able to print in two colors at once. This money would also be used to buy the necessary tools to test and configure the motors so that they are running in parallel (an oscilloscope helps wonders here), and so that we can ensure that each piece of the printer is held to the highest specifications possible (a digital caliper set helps wonders here). Once the necessary tools have been purchased, it will be easier to complete the HD^2 and pass along the savings to you, the potential owner!
The HD^2 has been a project many years in the making. It all started with a desire to create a 3d printer from parts. This resulted in our first 3d printer which we ever owned, the Mendel Maxx. To this day, we still use the Mendel Maxx for everyday printing needs. However, as time went on, we found that we wanted to upgrade to a dual extruder model, and a model which would do 1.75mm filament. This brought the desire to purchase a new 3d printer, the Replicator from MakerBot.
After waiting over EIGHT weeks to receive our printer, we finally received our Relicator from MakerBot. And although it had two extruders and was able to print 1.75mm filament, the price was quite high for the features that we received. Since we bought the printer, we have purchased several upgrades for the Replicator, which have increased the total cost as far as investment goes in the 3d printer which we had purchased.
With both printers in hand, the MendelMaxx and the Replicator, we decided that there must be a way to make all of both printer's features available in a cost-conscious model.
The solution: the all new HD^2, the world's first Heavy Duty AND High Definition Personal Desktop 3D Printer. With your choice of a basic kit model or a fully-assembled, fully-loaded model, now you can make your own 3d printer (with instructions included, of course) for much cheaper than most of our competition. Not only will you be helping to make this dream a reality, but you will also now be part of the ever-expanding 3d printing community!! 2014 WILL be the year of the HD^2, The World's First Heavy Duty AND High-Definition 3d printer!!
We are always open to suggestions and encourage everyone to let us know if you would prefer different stretch goals or items in addition to the current stretch goals. We will attempt to incorporate them into the budget, but as it stands, the items described above will be able to be offered to you at the corresponding funding levels! So tell your friends, let them check out the HD^2, and become part of the 3D Printing Community this year!!
Risks and Challenges
This project, just like any other is a work in progress. With experience building 3d printers in the past as well as over 30 years combined of electronics engineering experience, the HD^2 is a paramount achievement and the next logical step for two men who can't stop tinkering with anything electronic.
With over a year of design and after hundreds of hours in Google Sketchup, we finally have arrived at a design that we feel is superior to other 3d printers at the same price point. At each and every step along the way, we had to ask ourselves 'what can we do to make this better'. The final product: the all new HD^2 (squared).
Our project budget goal is to produce approximately 40 printers or more, in order to receive both quantity and shipping discounts. The budget for a minimum of 40 printers is to ensure that we are providing the highest-quality parts which results in a print like no other 3d printer currently available. Meeting this budget will, in turn, allow us to offer the HD^2 fully-assembled for under $1,800 USD!!
Since we are not compromising on any of the integral parts of the printer, the material cost is a large part of the budget. Ordering any number less than 40 from our parts suppliers will make each printer more expensive, so that is why the budget number is as stated: to be able to produce high-quality printers from high-quality parts. Any number under 40 will not allow us to produce the HD^2 for the amount promised as materials price increases as quantity decreases, and therefore any pledges will be returned as per Kickstarter policy.
Once we reach approximately 40 backers or over, this will allow us to create and manufacture the HD^2 on a small scale using just the creators of the project to create all the printers. Once the HD^2 has successfully been funded, we would use the money to order all the parts and materials necessary to assemble both the kits and the fully-assembled printers. In addition, we will also book the rooms for the hotel stay in NYC for those backers who choose the Exclusive New York City Launch Party. The parts may take up to 3-4 weeks to arrive, as larger orders generally take slightly longer to arrive. Once the parts have arrived, we will begin the process of assembling each and every printer by hand.
While doing this, we will also be filming over a hundred hours in HD video. Once shipped, each printer will come with written assembly instructions in electronic format, as well as the option for videos of assembly of the HD^2. These instructions will mainly be based on the footage that we will be shooting while we are assembling printers for backers, which shows practical, real-world applications of the written directions. These videos will be freely available to all owners of the HD^2. This ensures that assembly will not only be easy to follow, but there will also be an option for other users to upload their own videos, questions, or comments on a YouTube page or on our website.
Between the two creators, we have almost 40 years of combined technical knowledge, and you can be assured that the very last printer assembled will be built to the exact same rigid specifications as the very first printer. Quality will be assured by one person checking the other's work and vice-versa, in order to put another 'set of eyes' on the finished product to make sure that each and every printer is inspected, tested, and approved to be shipped before actually being shipped.
However, once we raise $300,000 or more, we will no longer be able to manufacture all the printers in a timely fashion on our own, and we will need to hire up to six additional people to help with the construction of the printers on a full-time, temporary basis.
These skilled workers will be working under a contract which is only short-term. They will be helping us assemble the finished printers, as well as clerical duties such as preparing shipments for pickup, and basic assembly tasks. Each printer will be inspected by one or both of the creators prior to it being shipped out. This maintains the quality standard throughout the entire production process. Having these employees will allow us to assemble all the printers that have been ordered, as well as ship and deliver them before the previously-set shipping date deadlines.
Should we hit a speedbump along the way, we will immediately let all of our backers know by posting an update as to what has happened with the project, and what the next course of action will be. There will always be unforseen complications along the road, but with proper planning and execution of our product marketing plan, we should eliminate most of these potential snags before they actually happen.
We will update during the course of the Kickstarter campaign once milestones have been reached, or if there are ANY questions at all to be answered!! Not only do we want to build lots more of these printers, but we also want feedback from you, our backers, once we have shipped the printer. The following questions are actually very important to us, and we would like to know from all backers who have received their HD^2, If you were in our position, what would you change (if anything)? and What is your favorite part of the HD^2 in five words or less. To us, the creators, the feedback is one of the most exciting and enjoyable parts of the creation process. Once you have seen us take raw materials and deliver them to your doorstep, we would like to hear from you to see what you enjoyed the most about our project.
Ultimately this is an open-source development project, and we intend to ship with each HD^2 the complete set of .STL or .3DS files for the printer!
We want you to have the most pleasant experience possible, whether you are brand new to 3d printing, or if you are computer-savvy and have been just WAITING for a printer like the HD^2.
Assembly instructions will also be available for all KITS sold, which will minimize the set-up and calibration process. By choosing to use open-source software, it allows you, the user, to be able to customize your HD^2 any way that you like. In addition, we use industrial-grade extruded aluminum on ALL load-bearing supports to allow you to add additional modules to the completed model with the ease of as little as one nut and one bolt!
Upon successful completion of the Kickstarter campaign, we will ALL be part of the same 3d Printing Community which continues to grow EVERY day! Not only that, we will be a community that will be able to provide support to one another through Kickstarter website updates, and when those are no longer available, from the website WeGotPlastic.Com. The more HD^2s that are out in the world, the greater the combined technical knowledge will be. This community approach to using a Public Forum for HD^2 owners will not only foster the pride of being a 3d printer owner, but it will also give owners a place to show off their creations and to address any and all potential problems.
After all, this all started with a community of people willing to help others achieve their dream, which is why we will continue the tradition by helping others through continued service and support.Learn about accountability on Kickstarter
The Z-motors are wired just as the board dictates. This board actually has two separate pin header sets for each individual Z motor, as well as spots for dual extruders. The board is pretty much awesome; we are using the RAMPS 1.4 board with 5 Polulolu drivers.
Open Source all the way! Using Open Source software will allow the end user what I think is the coolest option of all- complete customization and personalization! But I digress...
We are currently using Marlin firmware as it allows for more advanced configurations than Teacup or Sprinter. We are really firmly set upon using an open-source software design, as well as including a set of STL files for the 3D printer. This way, you would be able to use your HD^2 to print one for a friend, and so on and so forth. While doing that, we also want people to be able to modify their own printers via firmware configurations to suit their personal preferences. These are all the reasons why I chose the RAMPS 1.4 with Marlin firmware.
A higher resolution print will usually take longer to print than a normal print, and this is because the printer actually incorporates more details into the actual model. There will be closer spacing between layers, which is allowed by upgraded motors, stepper drivers, software configuration, and upgraded bearings and smooth rods to accompany the other hardware. Together, all these upgraded parts give the HD^2 the ability to print up to 25 microns, where (as the chart shows above) most other printers can only print up to 100 microns resolution.
Yes, you can! I wanted to make the product video shorter so that more people would make it through the entire video. If you would ONLY like to see the HD^2 printing, I have posted a video via YouTube of it printing that is about 30 seconds long. I mainly concentrated on taking still pictures of the printer, to show the concept to prototype transition, and unfortunately did not take many videos. The YouTube link is as follows: http://www.youtube.com/watch…
Unfortunately, the HD^2 will ship with a standard US-style 110v male plug for power connection from the power supply to the wall. The actual power supply, however, has built-in switching circuitry which will allow you to change the setting from 115v-230v much like a PC power supply. All you need to do is provide and install your own EU style plug and switch the setting.

Although it has not been tested with the HD^2. In theory it should work. From the NinjaFlex FAQ, it says that if your printer has a direct drive extruder (which we have TWO of on the HD^2) and is able to print in ABS (which the HD^2 can), you technically should be able to print in the new Ninjaflex filament.
