The Duplicator 4X is our first dedicated 1.75 mm filament extruder. This extruder was designed from scratch, and contains a number of custom manufactured parts. We’ve learned a lot over our past extruder designs, and incorporated a lot of those lessons here: that’s why it’s smaller, lighter, and faster to build. And since it’s designed from the ground up for 1.75 mm filament, it’s light-years ahead of past designs in small-filament reliability.

Plus order today and we'll throw in 2 FREE spools of filament... our gift to you! Great printer, great price, 1 year warranty (one of the longest in the industry!), ZERO tax, Free Shipping in the USA and FREE filament - how can you beat that!! Order today, this offer won't last forever!!

The layer alignment is much better which results in nicer prints and higher resolution; 100 micron/inch.

We’ve completely overhauled the drive system to give the optimum positioning accuracy. The entire system has been upgraded to sturdy 3/8″ diameter linear shafting. This is probably overkill, but you can trust that the axes will be sturdy. We’ve also switched to self-aligning, sintered stainless steel bearings. These are very forgiving to DIY assembly and provide a nice, smooth motion on the steel shafts. We’ve completely replaced the Z axis with a stepper driven, cantilevered stage. Guided by two of the linear shafts, this completely eliminates any Z wobble and results in nicely aligned layers. Using a high-angle lead screw, we were able to increase the speed of the Z axis from 150mm/minute to 1,000mm/minute. This means the layer changes are almost completely imperceptible.

Connect over USB and hit print the machine will calibrate itself and start printing.

The new electronics have been designed to make the printing experience easier than ever. The Duplicator 3D printers are a one connection deal to your computer via a standard USB cable thanks to a USB chip on the motherboard. We’ve also added full end stop support so that you never need to touch the XYZ axes ever again. When you hit print, the machine will automatically home itself, heat up, and begin printing. All you have to do is sit back and relax while your Duplicator 3D printer does all the work - or if you don't want to have to have your computer tied up while printing you can always print with a SD card since the Duplicator comes standard with a SD Card reader and LCD Screen.

The all new Duplicator 4X is such a solid machine, from a hobby machine to starting a business to using one in your lab I know you'll be very pleased with a Duplicator 4X printer - I have anywhere from 4 to 6 Duplicator 3D Printers running here at the shop nearly 24/7 and we are very pleased with their reliability and ease of use! Give one a try today, you'll be glad you did! Enjoy!!

What Temperature to 3D Print your Filament at?

While each 3D Printer is different and you will need to play around with the temps to get the best print here are some starter temps for you; these are all temperature profiles that are verified and confirmed print temps on the MakerGeeks.com 3D Printers (9 different machines from pre-built D3 and D4 to our own DIY custom Reprap printers) with the actual filament we sell to you... so they will get you 99% of the way there!

195c - 210c
210c - 215c
230c - 235c

175c - Smooth
210c - Rough

165c (light colored wood)
210c (very dark colored wood)

How do I get my filament to stick and STAY stuck?

This one is a multi-faceted answer but here are the basics:

  1. Your print bed has to be level!! I mean, spend some time on this one... if it isn't level like a... well... like something that's really level - then your print won't stick and it won't come out looking right.
  2. Next... CLEAN, CLEAN, then RE CLEAN, have a sandwich and a soda-pop and then CLEAN again... use acetone and a lint free towel to make sure your print surface is clean and free from oils and dirt.
  3. If you are having a hard time printing on glass try using some Kapton tape as that will give you a little better stick
  4. If you have a heated print surface... TURN IT ON!! Even when the filament used might not call for it, I always turn on my heat bed (who doesn't like a warm bed!!); even if it's just 40c it will really help. For PLA normally you'll want about 60c and for ABS you'll want 110c
  5. For ABS 3D Printing room temperature really matters... you need to keep your entire build warm; so if you can't print out in a warm room try putting a box over the printer to keep that build area as warm as possible.
  6. Try making "ABS Juice" - just add some scrap ABS filament to a bottle of acetone and let it dissolve and then use that to clean your print surface as normal; the dissolved ABS will give your printer extra STICK OR you can use "Aqua-Net Super Hold" hair spray (must be this brand to work right)... just clean your board as always and then lightly spray the Aqua-Net on the print board and print away (this method is my favorite as it seems to work best for me!)
  7. KEEP trying!! You'll get it and once you do have it dialed in then you have it forever... each printer is different; make sure you make notes of what works and what doesn't for each filament you use and each printer you have. So, in the future when you want to print out that EPIC "Yogi Bear" figurine in MakerGeeks.com Blue you know what to set up your GCODE for.

What is the main differences between PLA and ABS 3D Printer Filament?

The main difference between PLA filament and ABS filament is that ABS is produced from fossil fuels and PLA is derived from biological resources, which makes PLA plastic biodegradable. Check out this 3D Printing Filament Impact Test -- PLA vs ABS vs PETG vs Sledgehammer (click here to watch the videos)!! When it comes to 3D printing the key differences between ABS and PLA are:

  • PLA is a rigid liquid and ABS is a crystallized liquid, meaning that when heated ABS transits slowly from a gel to liquid and PLA transits direct from solid to liquid.
  • ABS is more flexible and PLA is more solid, meaning when stressed PLA will snap sooner.
  • PLA is more glossy looking consumable than ABS (see photos when selecting your material).�

Wow, you have a 1kg spool of filament... SO What! How much actual filament is that??

Big question of the day is... how long is a spool of 3D Printing Filament!? Hummmmm, I think even Blinky the wise old MakerGeeks.com owl might have a hard time with that question but never fear... we have the answer!!

1/kg Spool

PLA 1.75mm

PLA 3mm

ABS 1.75mm

ABS 3mm





... and what does that mean to me and you!! Well, check this out... if you are printing with 3.00mm filament for a iPhone case you need about 2,700mm of filament; for a EPIC Starship Enterprize Model you'll need about 12,000mm of 3D Filament and for a full Kossel 3D Printer Kit we normally use about 50,000mm of filament. Another way to look at it according to MakerBot is that 1 spool of 3D Filament produces about 392 full sized chess pieces. Whoa... that's a lot of chess!!
