The Prusa i3 Acrylic is a RepRap model originally designed by Josef Prusa. 3D Printer Czar redesigned its Acrylic Frame. Compared to its predecessors and other RepRap machines, Prusa i3 is known for its extreme ease of assembling, reliable printing, and dual extruder option. This kit uses laser-cut acrylic sheets to improve stability. In our experience, the Prusa i3 can be assembled within 3 hours, making it ideal for first-time RepRappers. |license = GPL

Q&A for Prusa i3 Acrylic

   Q: What other parts do I need to buy to get the Prusa i3 functioning?

A: This kit includes everything needed except for the power cord. This is the cable you use for everyday electronics from computer monitors to microwave. We do not include the power cord because we ship worldwide and different regions have different types of plugs. Also, to improve ABS print quality, a roll of Kapton tape is also recommended.

   Q: Safe is your packaging for this Prusa i3?

A: We use customized EPE foam and 5mm thick cardboard boxes to protect your printer. This is why we dare to include the 3mm borosilicate glass in our kit, and never had a problem with it.

   Q: How fast is your shipping for this Prusa i3?

A: Shipping to Europe and North America are done through DHL express free of charge (yes, it’s true!). Our customers receive the Prusa i3 typically within 4 days after shipping. We are working with DHL to help extend this service to the rest of the world, but right now we use Hong Kong Post to deliver Prusa i3 to Oceania, Asia, and South America (free of charge, of course!). The shipping is also speedy and fast, usually delivered within a week in Asia and two weeks in Oceania. One can also choose the SpeedPost service from Hong Kong Post if he/she wishes to get the Prusa i3 faster. We are very proud of our service and below are some snapshots of our past shipping.

   Q: What if some parts of my Prusa i3 are broken upon arrival?

A: We carefully inspect all the parts before packaging the Prusa i3 to minimize this from happening, but if that did happen, free replacement at free shipping, no question about it.
