FAQ

Here are some of the questions we get asked on a regular basis.  If you have a question and you can't find the answer below, please feel free to contact us.

 

FILAMENT:

What type of filament do you recommend I start with if I am new to 3D Printing?

We recommend you start using PLA and then move onto other kinds of filament.

Have you ever printed with Ninja Flex?

A: We get asked this 10x a day and the answer is yes we have tried...unsuccessfully. When Chris designed this printer ninja flex didn't exist. The problem is that the extruder drive wheel 'squishes' the filament flat and then it cannot fit through the guide holes. Ninjaflex is TPE and around 40D shore hardness. For now we CAN print TPC (45D shore) so very close!
But now that NinjaFlex is so popular, Chris has developed a new extruder that will be released in November 2015.  It will be an add-on that will allow you to print Ninja Flex and other flexible filaments.  It will just bolt on to RoVa3D's or MH3000's with 2 screws, no mods required, and replace one of the existing extruders.

Q: Will my printer come with filament?

A: We do not normally include filament in with the printer.  However if you are asking in regards to reselling the printers, we could bundle filament with the printer if that is what you would like to offer to your customers.  We will also give you a bulk order discount if you order a large quantity of filament with your printer.

Q: What are the spool dimensions compatible with the spool supports or the printer?

A: 165mm, 195mm and 220mm are the spool sizes that we use, but the printer will fit any filament spool up to 220 mm in diameter  You could create some kind of support for larger spools externally if the need is there.

Q: What size filament does your printer use?

A: Our printer can only accept 1.75mm filament which has twice the extruder resolution and is much more common.

Q: How many material profiles is the RoVa3D printer capable of working with, and what materials?

A: PLA, ABS, Soft PLA, HIPS, PVA, PET, PETT, Taulman, Laywoo, Laybrick, ESD, Conductive, POM, Carbon Fiber, Wood, Brick, Nylon, Poly carbonate, carbon nanotube, and other future high temperature materials that are in development.

Q: Do your printers use a proprietary filament?

A: We do sell various kinds of filament through Amazon, however you are free to use any brand of 1.75mm filament, in fact we encourage it!

 

EDUCATION:

Q: Do you offer a discount for schools?

A: Absolutely, we can give you 20% off regular price items & 10% off sale items and cool muscle upgrades.  This includes all printers, accessories and filament but excludes software & extended warranties.  With your printer purchase we will include 2 free rolls of filament, free tech support and extend our warranty from 6 months to 1 year.

 

SOFTWARE:

Q: Is the firmware open source?

A: Yes it is, you can find the latest version on our software page.

Q: Can I use my own tablet?

A: Yes any android tablet that will run the gcode printr software will work.

Q: What is Pronterface / Printrun for?

A: Printerface is the same as cura. It controls the printer. But another slicing program is required as well, since Pronterface doesn't have slicing built in.

Q: Is USB printing standard? Is Wifi an option?

A: Yes USB printing is standard but users may link to a device like Astroprint for wifi printing. There is also a micro SD card slot.

Q: If I create a design in Rhino 5, Max (or other 3D software), is it possible to import it in the 3D printer software and transform it for the printing process?

A: Yes any 3D design program will work with our printer.

Q: What CAD software is compatible with your printer(s)?

A: Fusion360, Solidworks, Sketchup, Rhino, 3ds Max, Autodesk inventor,
maya, autocad, Adobe Photoshop, and any other 3d design software that
can export an .STL file

 

WARRANTY:

Q: What warranty is on the printer?

A: All 100% of the 3D printer parts are warrantied against manufacturers defects for a full six(6) months! Users pay applicable shipping charges for warranty claims. You can purchase extended 1, 2 and 3 year warranties.

 

PRINT SIZE:

Q: What are the build volumes for 2 to 5 nozzle being used? or have you developed a chart (# of nozzles vs build volumes)?
A: You can find this answer in some of the updates from our original Kickstarter:

Q: Is the height limited to 191 mm, can it be increased to 250-300mm?

A: You can increase the height by cutting your model, and printing it in two piece, or arrange it to print on the print bed diagonally. 

 

ORDERING PROCESS:

Q: How is the order & payment process going to be?

A: If you would like place an order and live in North America you can place your order online and shipping will be calculated for you.  You can pay via Creditcard or Paypal online.  We also allow you to call us with your Credit Card, send us a cheque, or wire transfer.  You will receive an order number and will be put into the queue for shipping.  Generally the lead time is between 1 and 2 weeks.  Sometimes it may be a little longer depending on the upgrade options you choose as they need to be ordered in.  If you live outside of North America you will need to contact us with your address for a shipping quote. We will then invoice you and you are able to pay via Creditcard, PayPal, or wire transfer.   Please note we cannot accept net 30 day payments. All orders must be paid for in advance of shipment.

Q: What would be the delivery time be?

A: Shipping times vary depending on where you live. Once your order has shipped we will send you the tracking information, so that you can follow along and see the expected delivery date.

 

PRINTER Q’s:

Q: Does the printer come with nozzles? If so, which size?

A: Yes the printer comes with 5 x .5 nozzles. We also have .35 and .7 available on our site.

Q: Is every head customizable for temperature and extrusion speed?

A: Yes, because of the liquid cooling system each head can have a different temperature, Nozzle 1 could be 190 Celsius and nozzle 4 could be 400C no problem. Also, each extruder has it's own speed and extrusion multiplier set in the slicing software.

Q: Are the two hot end thermocouples accurate enough for controlling accurately low temp melting materials such as PLA or ABS or support material?

A: Temperature is controlled to within 1 degree Celsius by any of the temperature sensors. They can each hold independent temps from room temp up to 450C. So PLA and ABS are easy.

Q: How reliable is our printer?

A: Our printers are built to last.  We use only metal pulleys, metal gears, metal frames, injection molded plastic components, and stainless steel linear bearings.  They are built like a tank.

Q: Do you sell a glass base plate to print on directly instead of having to cover the plate with tape?

A: We don't sell a glass base plate option, but we do have customers that have had a custom piece of glass cut that they use on top of the bed for printing certain materials.

Q: If we hold off on the enclosure for now, can we purchase it later?

A: Absolutely, you do not need the enclosure, though we do recommend to schools to have one for safety precautions. It also helps to maintain an elevated and relatively consistent internal ambient temperature which is a key factor in the success of printing with ABS and some of the other tricky materials.

Q: Is there a liquid display and an operators commands menu to directly control the printer (for maintenance for instance or to print from a SD card)?

A: The tablet may be used to control the printer. There is no display permanently attached to the printer. We thought that the tablet was nicer because it's larger and touch enabled. Also it gives the customer the option to save some money if they want to control the printer with their own computer.

Q: Can metallic pieces (bolts, nuts) or other small items (various materials) be embedded into the product during the printing process?

A: Yes they can. You would need to pause it at the right moment and insert the components.

Q: Is the printer equipped with an auto leveling function?

A: Yes it does.

Q: If I buy less than a 5 Nozzle printer now, can I upgrade it later?

A: This one is tricky.  Due to the liquid cooling system, and the fact you would need to completely re-wire the printer - we recommend you bring in your printer to our manufacturing warehouse and we will upgrade it for you.  We suggest if you are going to want to have a 5 nozzle printer, start with it.  You can always print with 1 nozzle, 2 nozzles, etc at first and move up to using all 5 later.

MOTORS:

Q: You have so many stepper motor options - how do I know which one to choose?

A: High Speed, High Torque Stepper motors are the standard motors on the printer.  They are more powerful and faster then our competitors motors.  You have to have a motor of this caliber to be able to move the carriage and drive the extruders at the very high speed that our printer can obtain of 200+ mm/sec.
 
Stepper motors are a resonant device, they are like a musical instrument that play notes as they're operating.  This is very evident when they draw circles as the motors will "sing".  The frame amplifies the sounds, this is by no means loud, you can carry on a normal conversation and easily hear some body even if you are standing directly beside the printer when it is operating. However some people may find it annoying over time. Vibration Dampers decouple the stepper motors from the frame so that the vibrations cannot carry through the printer and amplified.  The result is a reduction of the volume of the sounds by 10 decibels.

The Cool Muscle line of servo motors provide all the common components required for motion control embedded into the motor itself. The seamless integration of both software and hardware components creates highly efficient motion modules and remove the problems associated with open loop steppers like skipped steps, electrical inefficiency, low max rpm's, and low resolution.  The Cool Muscle outperforms traditional servo and stepper systems by virtue of the controller's multiple closed feed-back loops with the driver and high resolution encoder while short wire lengths reduce susceptibility to EMI and noise.  You do not need vibration dampers if you add the cool muscle motors because as near as we can tell they are perfectly silent.  Further testament to their excellent quality.
