CEL Robox Refurbished Printer
The HeadLock system is a tool-less locking system with plenty of scope for high powered and complex additions to the rigid 3 axis frame. Robox is more than just a 3D printer.
Single Material Head (Included):
Needle Valves – A patented feature unique to Robox. Increases material compatibility and reduces flaws caused by stringing. A certain stop to the flow of material rather than relying on a retract as in all other 3D printers.
QuickFill™ Dual-Nozzle Technology – Although much faster than traditional prototyping methods 3D printing is not a fast process, Robox users can enable faster prints by using the large nozzle to fill unseen internal sections. Both nozzles can be used in the same print for faster print times without sacrificing detail. In this head both nozzles are fed from the same reel of material.
The large 0.8mm nozzle can quickly create a model with exceptional strength due to a large wall thickness and fast print time with large layer heights (up to 400 micron/0.4mm/400µm).
The small 0.3mm nozzle for fine details and extremely low layer heights (down to 20 micron/0.02mm/20µm).
Dual Material Head (optional):
Needle Valves – A patented feature unique to Robox.
2 nozzles – On this head the 2 nozzles are the same size and are fed by 2 separate material feeds. Use one nozzle for the build material and the other for a dissolvable support, or a material with different characteristics for a custom composite, or simply create a multi-colour print.
2 independently controlled heater elements give high levels of control across an immense range of materials.
HeadLock optional add-ons:
Future modules could turn Robox into an automated light machining rig, a 2D drag knife cutter or even a paste extruding system for ceramics, chocolate and a whole lot more.
ThermoSurface™ Build Plate and Heated Bed
Unique to Robox, 1mm thick and easily the best print surface for use with a heated or cold bed and most of the materials used in 3D printing today. ThermoSurface does not change size within the printers temperature range, when the part cools it shrinks and just pops off. No effort required, no risk of damage to the surface or the printed part.
Heated bed – Vital for printing in certain materials, Robox bed heat up time to 130°C is under 3 mins, less than half that of any of our competitors.
Removable 2 sided print surface – Almost no maintenance required, occasional cleaning of the flexible surface with alcohol at the most. Other 3D printers require disposable surfaces like masking tape or even hairspray.
Automatic levelling – Before every print, Robox probes the print surface multiple times building a map of the print surface. During a portion of the print the 2 independently controlled Z stepper motors will constantly adjust to maintain a perfect distance between the nozzle and the print surface. No interaction required, this is all automated.
Index wheel – The volume of filament is determined by the software and fed to the nozzles by a stepper motor, this is common of most 3D printers. Indexing in The Robox extruder enables automatic loading and fault detection and also measures filament used – The quantity of filament used to create printed parts is critical. So important, that Robox was designed to constantly check that the volume required matched that which was actually being fed to the nozzles. This design is so successful that another leading 3D printer brand immediately added a similar function to their flagship printer.
High torque due to worm gearbox – The required torque for most print materials is much less than this but this headroom allows Robox to print with a much wider range of materials and reduces the chance of print failures common in many other 3D printers.
Dual feed wheels for zero filament slip – In the Robox extruder the filament is trapped between 2 contra rotating wheels which grip and push the filament toward the nozzles.
Flexible filament compatible (2016 onward) – Extruders manufactured before Jan 2016 may not be compatible with flexible filament. Check with your seller, a small inexpensive change is required to enable this on older extruders.
Space for optional plug and play 2nd extruder – Every Robox has space and electronics for an independent 2nd extruder to enable multiple material or colour prints (requires Dual Material Head).
Each Robox filament SmartReel is fitted with a rewriteable EEPROM microchip to store material data and enable automatic recognition of a wide and growing range of materials we supply including PLA, ABS and HIPS in a choice of exciting colours. With this system, we already support the widest variety of materials on the market.
Robox users are not locked into a material system, Robox is able to use any compatible material from any manufacturer. In such a new and quickly developing world of material development it is very disappointing to see so many 3D printer manufactures limiting the creativity and inventiveness of their users.
Rigid 3 axis frame provides a basis for a highly accurate, low maintenance, cartesian system – This frame format is common of high end CNC machines and many other 3 axis machinery. By using this design and the HeadLock tool attachment we intend for Robox to be much more than just a 3D printer.
Enclosed build chamber for a controlled environment and reduced shrinkage – A 3D printer without a case will never achieve the same accuracy in such a wide range of materials as Robox.
Precision components – bearing surfaces are machined to an exceptional tolerance and matched to high quality linear bearings. Threaded bars are custom made with a metric fine pitch to increase accuracy in very low layer heights eg 20 micron.
User safety – The door locks while the internal surface have dangerous temperatures, this prevents accidental burns and injury from moving parts.
Desktop micro-manufacturing – Although just at home in a workshop environment, Robox has been designed so every desk can accommodate it, it looks great too! The external dimensions (370 x 340 x 240mm 14.5 x 13.4 x 9.4″) have a generous build area (210x150x100mm) – Although not as big as some, the studies we have done put over 90% of 3D printed parts well within these limits, even if you do need something bigger, the print time of large parts is prohibitive so splitting the part into smaller, easier to print sections is often wise.
AutoMaker is our free to use custom made interface software for Robox.
AutoMaker runs on most current operating systems in many languages.
A simple and intuitive interface has been designed over a powerful and controllable back end.
A novice user only needs to load some filament, choose from Draft, Normal and Fine print modes and place their model in the software. Pressing Make does the rest. 3 very easy steps with no prerequisite knowledge.
Advanced users will find plenty of control to manage the finest details within a print or material profile. These profiles can be edited and shared with other users in the community. A choice of slicing engines gives users the best of the best. Currently Cura and Slic3r are offered and our system has been designed so that more can be offered if they prove worthy.
Model repository integration allows users to grab a model from the internet so it loads directly into AutoMaker ready to print.
