Industrial 3D Printing

3D printing is where Additive Inn started, and it’s still the core of the workshop. Most of what we print is functional: prototypes, jigs and fixtures, enclosures and short runs of end-use parts for engineering teams. The difference is what surrounds it: most print services hand you a raw part; ours sits next to a paint booth, an electroplating line, and a design desk, so a print can leave the building looking like a finished product, not a prototype.

Pick the right process, not just a printer

Each process has its own page if you already know what you need: stereolithography (SLA) resin printing for fine detail and smooth, paintable surfaces, selective laser sintering (SLS) nylon printing for strong, functional parts with no support marks, Multi Jet Fusion (MJF) for the same tough nylon in black, or metal 3D printing for parts that need real metal strength. Not sure which fits? Send the file and the application, and we’ll recommend the process and material rather than quote blindly. Or start with our guide to choosing a process, which compares fused deposition modeling (FDM) with SLA and SLS.

Industrial parts we print

The process follows the job, and most of what goes through our printers is meant to work, not just to look right:

• Jigs and fixtures. A holding jig in carbon-fibre PETG keeps a client’s electronic connectors in fixed, repeatable positions for measurement, with a shaped pocket and clamp for each part.
• Enclosures and casings. The faceted body casing for an ST Engineering autonomous robot was printed in PLA panels and finished in matte black.
• From prototype to metal. A panel-mount adapter for an industrial flow meter was proved in PLA first, then 3D printed in metal so it locks into the equipment panel.
• Test rigs at full size. A wind tunnel built from bolted PLA segments, with a honeycomb flow straightener and a clear test section, for laminar-flow testing.
• Batches. SLS prints PA12 nylon with no support marks, and Multi Jet Fusion (MJF) prints black PA12 nylon a little smoother. Runs get cheaper with quantity, and our pricing guide shows how.
• Tight tolerances. When a dimension has to hold to ±0.05mm, CNC machining is the better route, and we’ll tell you so.

Beyond the build plate

• Large prints: pieces bigger than any single machine get split, printed in sections, and bonded with alignment features designed in. See how we approach large-scale printing.
• Finishing: sanding, priming, spray paint in Pantone-matched colours, clear coats, and electroplating over resin prints.
• Design support: no file? The concept to fabrication team can model from a sketch, a photo, or a physical sample. For a whole product taken from a brief to a tested prototype, see product development.
