ACCESSIBLE WAY TO RUN SLS
Where Inova Fits Best.
Inova is optimised for engineering teams that need strong (PA12, PA11) and/or flexible (TPU) parts with control over the process and total cost. It’s not for every application – use the guide to see if it’s a right fit for you.
Rigid, Functional Prototyping
Strong, accurate parts for form, fit & functional testing.
Engineering Validation Parts
Validate parts and assemblies in real conditions.
Low-Volume Production
Short-run end-use parts and bridge production.
Process Optimization
Tune SLS workflows and material use before scaling.
A strong fit when…
You need strong PA12 or TPU parts
You value owning the process
You value in-house control
You want long-term cost control
Your parts fit the build envelope
You have or can create tech appetite
Consider another approach when…
You only need very large parts
You require exotic materials
You only need color or aesthetics
You prefer service / outsourcing
The strongest fit is not a one-off print requirement. It is a workflow where prototypes, engineering aids or small production batches come back repeatedly and every external order adds delay, coordination and margin.

165 x 165 x 235MM: MAXIMAL BUILD VOLUME
What the Build Volume Means in Practice.
Chamber dimensions are useful, but real decisions depend on part size, orientation, nesting and the usable volume for a given material and process setup.
See examples below.
Print large functional components as a single piece – without splitting the design or assembling multiple sections.
Nest multiple complex geometries in one build and produce a complete set in a single print job.
Use the full build volume for efficient batch production, consistent output and a lower cost per part.

WORKFLOW / OPERABILITY
From Print File to the Next Build.
See how Inova MK2 and the Inova EPP work together across the complete SLS workflow – from preparing the job and controlling the build to recovering powder, cleaning the system, and getting ready to print again.
ONE CONNCETED PRODUCTION CYCLE
7 STEPS ● 2 SYSTEMS
Turn your 3D models into an efficient SLS build.
Use SLS4All Compact SW to import and orient your parts, create the nesting, select the appropriate material profile, and set the build parameters. Once the job is ready, review the setup before printing.
Prepare the build chamber with the required powder.
Follow the print wizard, load the selected material and confirm that the printer is ready for the job. The open material approach lets you work with proven SLS polymers while retaining control over your processing parameters.
Let Inova MK2 control the build layer by layer.
Printer manages powder deposition, heating, and laser exposure according to the selected process profile. User interface provides access to the job status and throughout the process.
Allow the build to cool under controlled conditions.
After printing, the complete powder cake remains inside the build chamber while it cools. A suitable cooling period helps protect part geometry, dimensional stability, and final mechanical properties.
Transfer the cooled powder cake to post-processing.
Once the build has reached a suitable handling temperature, remove it from the printer and transfer it to the EPP workspace. The parts remain supported and protected by the surrounding powder until unpacking begins.
Separate finished parts and recover material for reuse.
Use the Inova EPP to unpack the build, clean residual powder from the printed parts, and collect the surrounding material. The recovered powder is then sifted to remove agglomerates and contamination before reuse.
Close the workflow and return the system to a ready state.
Mix the recovered powder with the required proportion of fresh material. Use the EPP workspace to collect powder while cleaning the printer, build chamber, and relevant working areas.

OWNERSHIP / OPERABILITY
Keep Inova Ready, Build After Build.
A clear build-to-build routine and system-guided maintenance make day-to-day care straightforward and future service easier to plan.
Inova MK2 is designed for straightforward, repeatable operation. Regular cleaning and material handling follow a clear routine, while operating-hour data helps your team understand when key components may require attention.
Getting Started
Initial setup and operator onboarding cover the essential checks, calibration and operating procedures. Once completed, these steps establish a reliable baseline for everyday production.
Between Builds
After each completed build, remove the cooled build, recover reusable powder, inspect the relevant areas and prepare the chamber for the next job. Keeping this sequence consistent helps the printer remain ready for production.
Routine Cleaning
Residual powder should be removed regularly from the build chamber and other relevant areas. A clean system supports dependable operation and consistent part quality.
Powder Management
Store, handle and refresh powder according to the selected material and process profile. Tracking material batches and refresh ratios helps maintain predictable powder properties across repeated builds.
Planned Maintenance
Inova automatically records the operating hours of key components. Based on these data, the system estimates their remaining service life or indicates when an inspection may be required, giving operators a clearer basis for planning maintenance.
Consumables & Support
Clear documentation and direct technical support help operators perform routine care and understand upcoming service needs. Keeping commonly used consumables and selected service parts available can also shorten routine interventions.

BUYERS FAQ
What You Need to Know Before Choosing Inova.
Straight answers about materials, installation, workflow, maintenance and delivery – so you can decide whether Inova MK2 is the right fit for your team.
Inova MK2 is designed for polymer SLS powders, including PA12, PA11 and TPU. Its open-material approach lets you adjust processing parameters, create your own profiles and evaluate compatible third-party powders instead of being locked into a single material supplier.
The usable build volume is 165 × 165 × 235 mm, giving you enough space for one large component or a densely nested batch of smaller parts.
Because SLS requires no support structures, parts can be arranged throughout the available volume. The practical maximum size may vary slightly depending on part orientation and the clearance required around the build
Inova MK2 is designed to fit into a workshop, prototyping lab or engineering environment without dedicated industrial infrastructure. You need a stable working surface, suitable access around the machine, the correct mains supply and adequate room ventilation.
Export your model from CAD, upload it to SLS4All Compact SW and prepare the entire job in one integrated environment. The software handles model placement, nesting, slicing, material profiles and printer control.
After printing and cooling, remove the powder cake, recover the unused powder and clean the parts. No support removal or curing stage is required.
Regular operation mainly involves powder handling, cleaning powder-contact areas and checking components such as filters, seals and optics protection.
The software provides maintenance guidance and estimates when key components should be inspected or replaced. The modular construction also allows many service tasks and component replacements to be handled directly by the owner.
