Who am I?
I have always loved building
things. I was famous as a kid for
building cat traps to try and catch the neighborhood cats. When I went to college, I tried to maximize my future opportunities
for making things by studying engineering and business. When I finished
7 years of college in 2002 I still didn’t know what I wanted to do. My wife and
would joke all the time about “what I wanted to be when I grew up.”
For the past decade I have been producing fun software and products for well-known companies. You can read more about me in my
bio. The link is located just to the right of this text under my picture.
Why did I decide to sell the TangiBot?
I started following 3D Printers about
3 years ago. I even convinced my
employer at that time to buy a 3D Printer. I was hoping I could somehow tie it
into what I was doing at work ;-) Recently
I had the thought, “If I can’t decide what type of product to make why not make a product that makes stuff?” I am currently pursuing this dream full time.
I love 3D Printing. It’s an amazing thing to hold something in
your hand that was only a thought a few moments earlier. I want to get 3D Printers into the hands of
more people so that we can see what amazing things might happen when their dreams
become tangible – something real that can be shared. Lowering the price is the first step.
As I work to launch the TangiBot I am working 60-80 weeks on a regular basis. Not a minute of it has felt like work. When you are pursuing a passion it just feels
What does supporting this project mean to you?
By backing this project you are doing one or more of the following:
- Pre-purchasing a TangiBot
- Making a contribution for which you will receive a token of appreciation (a printed medallion and your name listed on the company website forever)
- Or maybe you just want to show your support for taking an open source design to the masses (see question 1 in the FAQs below)
What is a
The TangiBot is
a clone of a very popular open source 3D Printer. It offers the same great performance and features but it costs roughly 2/3 what others will charge you for it. Depending on the model you buy, that is anywhere from $550-700 off! The TangiBot is 100% compatible with firmware
upgrades, parts and accessories that are available from multiple suppliers on the internet. Because the TangiBot uses a popular design there is also a very active community that also supports the machine.
Does the TangiBot differ from the
popular open source design in anyway?
So a price drop
of ~33% isn’t a big enough difference for you?
OK, keep reading…
I chose this design
because it is proven, popular and has a very active community. I didn't want
backers of this project to have to take a gamble on an unproven design. One of
my goals is to remain 100% compatible with parts already being supplied for
this design. Because of this I am
limited in the changes I can make. Most of the changes that are being made are
manufacturing changes. Because the manufacturing process is currently being
developed it is constantly being evaluated and improved. I do not have a complete list of all the
improvements at this time but here is a short list of some of the changes:
the PCB (motherboard) so that it is compliant with FCC regulations
lock and locking washers/nuts on important bolts to limit the amount of
maintenance that must be done on the TangiBot
the PCB (the motherboard) so that it cannot be easily shorted out by loose
screws or other objects
key plywood parts with plastic parts (like the z-axis guide rod mounting
- An Acrylic
case (for those of you who chose to buy acrylic)
There are a few
other improvements that are being kicked around such as closing in the sides of
the case. But big changes, like enclosing the sides, will be fully vetted by
engineering and approved by my backers before they are implemented.
If you didn’t understand all of what I just
said, don’t worry. It simply means that
your TangiBot will print the best quality parts possible when compared to the
prints from other machines using the same open source design.
Why should you buy a TangiBot?
The TangiBot is the best 3D printer on the market. The awards this design has won and the popularity of its open design is a testament to that fact. Here is a quick list of the benefits of buying a TangiBot:
- 2/3 the price of what others are selling the same design (discount of $550-700)
- You can get it fully assembled and tested in Acrylic (only available here)
- The highest quality 3D Printer
- The best features
- A very active community of owners
- Thousands of 3D designs available to download and print online
- Design your own parts, toys, games, and models
Why are there 4 different models of TangiBot?
The standard TangiBot comes in a high quality plywood case with a single extruder. You can also buy the TangiBot in an acrylic (plastic) case or with a dual extruder. The dual extruder is capable of printing more than one color of plastic at the same time. Your four options are:
- ($1199) Plywood Single Extrusion
- ($1299) Acrylic Single Extrusion
- ($1299) Plywood Dual Extrusion
- ($1399) Acrylic Dual Extrusion
Please keep in mind that if you want to buy a fully assembled and tested TangiBot in Acrylic you can only get it here.
How do you use the TangiBot?
The TangiBot prints anything you can imagine out of ABS plastic (and PLA). ABS is the same plastic used in Legos You can design your own parts using free tools like tinkerCAD.com or Google Sketchup. If you have access to a professional CAD tool like ProEngineer or Solidworks, those tools will also work. You can also download parts online. One of the biggest and most popular places to download parts is thingiverse.com. Many of the online design tools (like tinkerCAD) also have databases where you can search for parts to print.
Don't let the word "CAD" intimidate you. CAD has long been a tool for professional engineers but in the last few years many free and easy to use tools have become available to the public. I am a big fan of tinkerCAD because it is so easy to use.
What can you use your printed parts for?
I have used the parts I printed for all kinds of things. Here is a list of some of the things I have printed on my TangiBot in the past few weeks:
- Parts to fix the icemaker in my fridge (this saved me $100 in parts and $75 for a repair man)
- New parts for my tripod (this saved me $25 and 1 week I didn't have to wait for shipping)
- Parts to fix my toilet (this saved me $45 in parts and a trip to the hardware store)
- A mount for my smart phone to attach to the handlebars of my bike (similar products cost $20-25 and mine works exactly the way I want it to because I printed it)
- Custom hangers to hang things like my kids Nerf guns on the wall
- Desk accessories (pen holders, etc.)
- A penny catapult and many blocks for the game SEEJ (search for SEEJ on thingiverse.com)
- Tool holders and organizers for my shop
- Drink coasters with my kids names on them
- Toys for my kids and the neighborhood kids
- Engineering prototype parts
My TangiBot regularly runs 10-12 hours a day printing all kinds of things. In the past few weeks my TangiBot has saved me about $300-350 because I have made things instead of having to buy them.
How much does the Plastic Cost?
Plastic can be bought from many sources on the internet. The TangiBot uses 1.75/1.8mm filament plastic. It can use either ABS or PLA plastic. For 1Kg (2.2 lbs) of ABS plastic you will spend anywhere from $25-45 depending on the color and who you buy it from. Plastic comes in all colors. There are even special colors available like glow in the dark!
Your single extrusion TangiBot comes with 1Kg (2.2 lbs) of white ABS plastic. The dual extrusion TangiBot comes with 2Kg of plastic - 1Kg of while and 1 Kg of black.
How much will 1Kg (2.2 lbs.) of plastic print?
This is a tough question because it really depends on what you print. I printed all of the stuff I listed above and used about 75% of a 1Kg spool. Similar to a computers "draft" mode, the TangiBot has different settings you can use to control how much plastic you use when you print. For example, you can decide if you want your parts to be anywhere from hollow to 100% solid. In my example above, where I used 75% of a 1Kg spool, I printed most of the parts anywhere between 10% solid and 33% solid.
I have included the "cost to print" for the projects I have listed in my project updates.
Why am I on Kickstarter?
I am ready to start production but don't have the money. I need 400 people to pre-order the TangiBot so that I can begin production. This is where you come in. Please buy a TangiBot today. If you live outside the continental United States please be sure to buy the international shipping reward.
How was this
you saw in the video was made by taking parts from three different sources.
manufactured some of the parts locally in Utah
- I bought parts
like rods, motors, linear bearings, screws, nuts, etc. from suppliers
parts from a Makerbot Replicator
cries foul and claims that using parts from someone else's product in my prototype is cheating please consider the following example. I have not yet
produced any tooling to manufacture plastic parts. Plastics tooling requires a
significant investment of money and yet, I need my prototype to be as close to
production quality as possible. The parts I produce with my own plastic tooling
will be identical to those made by Makerbot. Because of this, I used the
plastic parts from a Makerbot Replicator in my TangiBot.
Using someone else's parts in a prototype is a very common engineering practice.
consists of me and a professional network of firmware, software, electrical,
mechanical, and manufacturing engineers as well as manufacturing facilities.
This is the same network of professionals that I used to develop Cricut
Products while I was employed by Provo Craft. One of my key partners is VPI Engineering located in Draper, UT. You can read more about them here if you are interested http://www.vpiengineering.com.
If this project
funds I will need to hire a few people in the coming months to help handle
things like customer service, sales and marketing. I am serious about building
a world class product. A world class product includes world class support. As the needs of the TangiBot grow I plan on investing in
At a very high level, here are the
steps that I will follow as soon as the project funds:
production files for tooling
and launch company website (including customer service portal)
first round of production samples from production tooling
tooling and setup production line
golden production samples
Why you can trust that
3DTangible will deliver
For the past 7 years I have been developing, producing, and
supporting electronic paper cutters for Provo Craft. Paper Cutters and 3D printers have a lot in
common. I still have access to all of
the same world class resources that I had during my time at Provo Craft. I will use this same network to produce the
TangiBot and develop next generation 3D printers.
I built a prototype.
At the time of posting this Kickstarter project, it has been running
from 8AM-5PM, 6 days a week for the past 3 weeks. I have run almost 4 complete 2.2 lbs. spools
of ABS through the machine and it is still going. That is almost 10 lbs. of
Since leaving my full time job in mid-May to pursue 3D
printing full time I have done nothing but research, build and prepare to manufacture
the TangiBot. Before this, I have
followed 3D printing very closely. I am
now at the point that I can start production tooling but I don’t have the
money. This is why I have come to
Here is a bulleted list of some of my other qualifications:
- 7 years of
experience developing, producing and supporting electronic paper cutters
10 years of
experience in software and firmware development, support and production
network of professionals
Please see my bio for more specific information regarding my qualifications.
Warranty and Replacements
The TangiBot does not carry any long-term warranty. 3DTangible will happily work with you to replace any manufacturer defective parts and get your TangiBot running in tip-top shape. This is the same warranty that most 3D Printer manufacturers provide.
Support will be offered by 3DTangible through our website. In addition, because the TangiBot uses a popular open source design, there are also many forums and groups of users that are happy to provide tips and help.
How is 3DTangible able to make a Clone?
The design used in the TangiBot is open source. In other words, people who have contributed to the design make the design publically available on the internet. Why do they do this? Well, it may surprise some of you that they are required to do this. Companies that used other open source designs when designing and producing their 3DPrinters. When someone uses an open source design in their product they are required to share any improvements in the design with the world. In other words, if you use open source and then improve on the design you have to share that improvement so that the rest of the world can benefit from it. 3DTangible will also be bound by these same laws and all the improvements we make to the design will also be shared with the public.
Just to be clear, there is nothing illegal, sneaky or underhanded going on here. Everything is legal and fair. This is simply the way open source designs work. Welcome to the world of open source.
