Why Do I Need One?
Students using SolidWorks or any mainstream 3D CAD platform will, sooner or later, need to turn ideas into real parts for projects. 3D milling has its place, but an accurate, functional part in ABS plastic will often do the job well. uPrint SE Plus and Mojo machines build using Fused Deposition Modelling (or FDM) by extruding a fine filament of molten ABS plastic. A second filament of support structure is also extruded.
Soluble Support Advantage
Mojo and uPrint SE Plus both use SST (Soluble Support Technology), the support material being gently removed by dissolving away. With SST (Soluble Support Technology) there is no limit to the complexity of the part you can build. For most jobs, parts will be completely functional and can be used straight from the machine. Their smooth-textured, satin finish is not unattractive and faithfully represents both the dimensional and aesthetic qualities of the CAD model.
uPrint has been developed to give designers a truly in-house means of Rapid Prototyping with no compromise on part quality. Mojo takes this class-leading technology and presents it in the most compact desktop format yet to be seen. TechSoft have been selling Stratasys FDM machines into education since 2004 so we know how accurate and reliable the process is.
Which Machine Should I Choose?
If the budget allows, the uPrint SE Plus will give schools and colleges everything they need with this professional reliable 3D printer. The Mojo offers educational users additional benefits in that the model and support material are each supplied as a complete QuickPack™ Print Engine cartridge that simply slots into the machine, meaning minimal maintenance and no calibration or set-up routine. Both machines are supplied with software to import 3D .stl files and build them. The software allows students to set a preferred build strategy and analyse the effect of these settings before committing to a build. Mojo requires a dedicated PC to operate the machine; uPrint SE Plus downloads the file and builds the model independently.
Support Removal System
uPrint SE Plus machines are supplied with the SCA-1200HDT Support Removal System. The SCA-1200HDT has a large load capacity and the Ecoworks solution remains in the tank until no longer effective. It is then manually drained and replenished - parts are hand washed in a sink.
Mojo has its own WaveWash 55 system which needs no plumbing and sits on the desktop just like a domestic kettle. All systems run quietly to dissolve away support material, they make no mess and are designed for ease of use.
