FAQ

Find the Answer You Need

How big can Gigabot print?

Gigabot can print objects up to 600 x 600 x 600 mm, providing plenty of room to print your dreams!

How big is Gigabot?

Gigabot weighs about 100 lbs with a footprint of 40”L x 34”W x 40”H.

How fast can Gigabot print?

Gigabot can print at over 100 mm/sec. An iPhone 4 case can be printed in 40 min at 0.2 mm layer height. The large vase on Kickstarter took 24 hours. Print time depends on several factors including layer thickness, object density, infill pattern and the geometry of the object.

How reliable is Gigabot?

Gigabot is designed to be as simple as possible but no simpler. Taking inspiration from agricultural equipment, architecture and the aerospace industry we feel the Gigabot provides the most robust platform for your 3D printing needs. There are very few moving parts to break or wear out. High quality components are used throughout the machine and all custom machined components are made in-house for the highest quality control.

How much does it cost (electrical cost) to operate the machine for an hour?

Gigabot uses only 150 watt when the heated bed is off and up to 950 watt with the heated bed on. If the cost of electricity is $0.10/ kWhr then operating cost for electricity would be between 1.5 and 9.5 cents/hour.

How accurate/precise is Gigabot?

Gigabot’s motors and electronics resolve linear position to 4 microns in X and Y and 2.5 micron in Z. Gigabot can print 100 microns layers. The smallest print you can create is a single dot, 650 microns. Gigabot is repeatable to less than 0.2mm.

What type of hot end do you use?

Gigabot currently uses the J-head hot end seen at http://reprap.org/wiki/J_Head_Nozzle with 0.5mm diameter orfice. It is an extremely reliable hot-end.

Does Gigabot have only one extruder or multiple? Can more than one be installed?

Right now there is only single extruder. The hardware and software were designed with the future in mind and will soon support multiple extruders. We hope to officially release a dual extruder by March 2014.

Does it operate on 110v or 220v?

Gigabot will run on either 110V 60Hz or 220V 50Hz power with a flip of a switch.

Is the software open source?

The current version of the Gigabot has incorporated several open source packages, the most notable being the Marlin firmware on the controller board. We encourage the use of Pronterface and Slic3r on the user-interface side, and tutorials will be released using these packages. Repetier is also used within the team quite a bit, and we anticipate transitioning to this more feature-rich tool.

Will the machine run unattended overnight. What happens if it runs out of material?

Gigabot can unattended. Our longest print to date is 46hrs. However, the printer does not automatically detect faults or failures and please keep in mind that high temperatures needed to melt plastic can also cause fires. So do please use caution. Gigabot will not automatically detect if it is low on filament.

Where can I buy a Gigabot?

You can purchase your Gigabot at: http://re3d.myshopify.com.

How much is shipping?

Shipping is calculated prior to checkout at http://re3d.myshopify.com.

When will I receive my Gigabot?

There is currently an 8 week lead time on orders taken today. We are working hard to accelerate the fulfillment process by scaling our operations and streamlining our processes.

What are the specific parts in the pre-assembled Gigabot that are assembled?

About 75% of the the assembly work is already done, and the only calibration left to do is to level the bed and fine-tuning the extruder.

Is there any warranty?

We don’t offer a warranty or maintenance plan at this point. We’ll be publishing instructions for repairs, and of course the community can also help each other out with common pitfalls (of which we hope there will be few!). Of course if a part arrives broken or unusable, we will work with you to get you what you need.

Does filament come with the Gigabot?

We send a 5 lb spool of PLA with your Gigabot. We also stock high quality filament in a variety of colors.

Can I buy a bigger or smaller Gigabot?

Sure! Please send your needs and specific dimensions to sales@re3d.org and we can provide a quote for your custom needs.

What types of filament can Gigabot use?

Right now Gigabot supports 3mm PLA filament. We will soon be releasing a heated bed that will facilitate the use of many other 3D printer filaments.

How much does filament cost?

We offer 5lb spools of PLA goes for $95 USD.

Can you use nylon for printing?

Yes, but nylon requires a fibrous surface for it to stick to - a good one is fiberboard or Garolite.

Is printing with poly-carbonate an option with Gigabot?

The high temp required to print poly-carbonate will require a different hot-end than is currently shipped with Gigabot. We also designed Gigabot to easily switch to another hot-end.

How much does filament shrink with Gigabot?

Shrinkage is a material dependent variable, independent of Gigabot.
We have noticed that PLA shrinks a little bit. ABS shrinks more.
ABS appears to lift or curl due to uncontrolled shrinkage.
Other materials shrink less than PLA.

Fortunately you can adjust calibration so your part comes out exact size you want it to. Any shrinkage is often small, it's on the order of microns.

If I used your filament to make a mold (ex; 3"W x 3"L x 2"H), how much pressure from a press could it take and at what temperatures?

The filaments we use are listed below. We have not performed an destructive testing and cannot guarantee any particular mold shape or design to withstand a particular rated load. PLA -glass transition temperature between 60-65 °C, a melting temperature between 173-178 °C and a tensile modulus between 2.7-16 GPa. ABS - Maximum Temperature: 176°F 80°C Minimum Temperature: -4°F -20°C Melting Point: 221°F 105°C Tensile Strength: 4,300 psi.

How much time does it take to assemble the Gigabot parts kit?

We recommend that first time builders prepare for a weekend of assembly fun. However, depending upon your mechanical aptitude and how many hands you have helping out the process could be completed in as little as 6 hours.

How much time does it take to assemble the Gigabot minimal assembly version?

We recommend that first time builders prepare 6 hours of assembly and calibration. However, depending upon your mechanical aptitude, the process could be completed much quicker.

What is the most complex part to assemble? About how long does it take?

The most important part is the Z axis and bed assembly. They need to be aligned, straight and level for optimal operations. New users usually require 2 hours to complete calibration.

What is the calibration process for the Gigabot? How complex is it and what tools are needed?

We will provide all the tools necessary to calibrate your Gigabot, as well as a host of video instructions on how to do so. You want you to take your time with this process, as it is crucial to the setup of any 3D printer.

How do I print a 3D model?

To 3D print on a plastic extrusion printer like Gigabot, 3D models in an STL format must be ‘sliced’. This turns the 3D geometry of the STL file into a series of commands (G-code) that break the model down into machine-readable lines of commands using an application like Slic3r.

G-code is then sent to Gigabot using a program such as Pronterface or Repetier. Gigabot uses an Azteeg X3 printer controller which is preloaded with Marlin Firmware.The entire software tool chain is open-source and freely downloadable for Mac, Windows and Linux.

How do I obtain a 3D model?

To 3D print, you may use a prepared model from websites like Thingiverse, or create your own model via 123D Catch/Design, Google Sketchup, AutoCAD, or any of a variety of applications which output their models in a .STL file format.

What is slicing?

Slicing basically divides the 3D model into very thin, horizontal layers. The printer will then lay out plastic layer by layer starting at the bottom. The thickness of the layers can be set on the slicing engine, but it is usually between 0.1 and 0.4 mm.

Why is the 1st layer important?

Since the printer builds objects from the bottom up, the first layer of a print is very important. The first layer needs to stick well to the flat surface of the printer, so a flat base will give the model a solid start.

Can you print overhangs?

Any overhang, or cantilever, shallower than about 45° cannot be printed without support material because the object will tend to sag. Support material can be easily calculated by slicing and automatically built by the printer.

How thin can you print?

Extruded plastic filament is around 0.7mm thick.

How do you control wall thickness?

You can control wall thickness by under or over extrusion, and this variable is controlled through Slic3r.

Do we need special software to convert our CAD models into a machine readable format?

The process for converting a 3D CAD model is to export as a .stl file, process the .stl into g-code using a translator (slicer) program and then run the g-code on Gigabot to print your model. The entire software tool chain is open-source and freely downloadable for Mac, Windows and Linux.

Can you recommend a 3D scanner?

We have used the Next Engine 3D scanner (http://www.nextengine.com/product) to make prints on Gigabot. Our designer friends have found it to be a good scanner at a good price ($3000 USD).
