Roland SRM-20E

The SRM-20E is a fully featured 3-Axis CNC milling machine which provides an excellent resource for one-off 2D and 2.5D projects in plastics and common modelling materials. Output for this purpose is direct from 2D Design V2 using the simple, familiar output routine. The SRM-20E also comes into its own for 3D work. The 203 x 152 x 60mm machining envelope is very generous for a machine in this class and will allow for most individual student projects. Models can be machined to fine tolerances with an excellent surface finish. To maximise work flow in a busy workshop, schools could usefully create a 3D Rapid Prototyping centre using two or more SRM-20Es rather than a single, higher capacity but more expensive machine. Machines are supplied with a TechSoft Inset pack and Roland utility software to convert .stl format files for machining. SRM-20 is compatible with Visual Toolpath. Although at additional cost, we recommend Visual Toolpath as the most student-friendly way to convert .stl files and configure 3D output.


Although an entry-level machine, the SRM-20E is designed and built to professional standards specifically to provide in-house SRM (Subtractive Rapid Manufacturing) capability in a professional design studio. In education, an SRM-20E is sufficiently robust to stand the rigours of the classroom but remains a compact, self-contained resource that could safely be moved if required. Output speed and work capacity is ideal for individual student projects and batch production of smaller items.


SRM-20E is a friendly, safe and simple machine to use which makes it ideal to introduce genuine CAD/CAM milling to primary pupils. We have developed our 2D Primary software to output directly to SRM-20E. Individual pupils or small groups can now machine their own badges, puzzles or moulds with unprecedented accuracy. They will be learning about modern production methods and gaining experience with a real computer control system.



Additive Rapid Manufacturing (3D printing) sits alongside Subtractive Rapid Manufacturing (milling) as an alternative 3D prototyping technique. Taken together, SRM and ARM gives designers the versatility they need to be able to produce prototypes and end-use parts for a huge variety of applications. The matched-styling of the ARM-10 and SRM-20E therefore makes perfect sense! The ARM-10 is Roland’s ground-breaking new 3D Printer that builds with photo-sensitive resins and an image projection system to cure successive model layers. Resins and materials used in the ARM-10 process do need careful handling though, so classroom use will need close supervision.
