DUAL P3STEEL by HTA3D - DIY Kit

Frame, it is the main component of the printer structure and provides the rigidity and stability: 

• Galvanized: it is the option by default and offers the best price-quality relation. The galvanized is a treatment that penetrates the steel, so unlike the lacquered, it will not get damaged during the assembly 
• Stainless Steel 304: it offers an unbeatable corrosion resistance and a premium look to your printer. Recommended for studios and shops that will have it shown 

Z Axis,  it is the axis that performs the vertical movement, it has a great repercussion in the layer precision: 

• Original: M5. The classic option, it works very well and without any clearances due to the nylon nuts (8.000 steps per mm) 
• Improved version: Trapezoidal spindles T8x8. It is a very popular improvement that substitutes the M5 threaded rods for precision rods, they are more resistant and they offer higher movement speeds (800 steps per mm) 
• Improved version: 17HS4401s-T8x8-310mm. These motors with integrated leadscrews, provide an extraordinarily accurate movement in Z axis. The rods are thicker which prevents them form bending, the friction is minimum and they can reach higher speeds than the threaded rods. As they don't use flexible coupler shafts the rod is perfectly aligned with the axis of rotation of the motor, avoiding the sometimes annoying "Z Wave" (800 steps per mm) - (Recommended Option) 

Hotend Dual Configuration, it is the element that melts the filament. As it is dual, you can choose a configuration for each hotend or the same for both: 

• All Metal: it doesn't have teflon components in the hot zone, thus it can reach very high temperatures and work with technic filament (Maximum temperature 300ºC) 
• With Teflon: the path of the filament from the pulley to the fusion zone is performed inside the teflon tube, thus the friction is minimized and it is very easy to use. Ideal for flexible filaments (Maximum temperature 245ºC-260ºC)
• Titanium: All-metal throat, made entirely of titanium and with a mirror polished interior, significantly improves performance compared to all-metal stainless steel throats, it is a highly recommended option (quality/price).
  
• Bi-Metal: It is an all-metal throat with a revolutionary design that provides a huge improvement in performance and reliability. 
  

Nozzle, it the extreme of the extruder, and defines the thickness of the filament being extruded: 

We offer a wide range to choose from for your application, nozzles around 0.4mm are the most popular choices. Smaller diameters provide higher resolution and larger diameters print faster and stronger parts

Printing Surface, it heats up the surface so the filament can adhere to it easily: 

• Mk2b Black: It is the option by default, it heats up very well and reach temperature higher than 90ºC.
• Mk2b Red: It is the option by default, it heats up very well and reach temperature higher than 90ºC.
• Mk3 Alu Heatbed: with 3mm of thickness of aluminium, it is especially flat, and distributes the temperature in a very uniform way. It is also heavier and heats up slower.
• Mk3 Alu Heatbed 220x220: Improved Mk3 version, which hides the head of the screws and is slightly larger.

Ramps (RepRap Arduino Mega Pololu Shield), it is the electronic component that controls the printer power: 

• Ramps 1.4: without any doubt the most popular electronic for your 3d printer 
• Ramps 1.5: Improved version of the Ramps 1.4, supports higher current intensity.
• Ramps 1.6+: Excellent quality version and mosfet WSK220N04 (recommended)
  

Lineal Movement:

• 12x Lm8uu: Ball bearing widely used in 3D Printers, it works very well and have a long shelf life - (Recommended Option)
• 8x Igus DryLin® RJ4JP 01-08 + 4x Lm8uu (for Z Axis): The Z axis moves at low speeds, so the difference in sound from one version to another is not perceptible, it is a balanced option
• IGUS DRYLIN® RJ4JP 01-08: Without ball bearings, manufactured in Germany made of a special low friction polymer, they are quieter and more precise than Lm8uu. They also add friction and are more difficult to assemble; recommended for experienced users

You can add some extras for your kit. We recommend the borosilicate tempered glass, as it is the perfect 3D printing surface, it is very flat, resistant and easy to clean 

Assembly:

Kit - DIY - Uploaded firmware and calibrated stepper motor drivers: without any extra cost, we assemble your electronic, uploaded the firmware and calibrate the stepper motor drivers ¡just to make it easier for you! 

We do it based on the chosen configuration, we can also upload the firmwate in the language you prefer (just leaving a note with the purchase or emailing us to info@hta3d.com. By default, it will be uploaded in the official language of the destination country.
