Selective Laser Sintering fuses engineering-grade nylon powders into strong, isotropic parts — no support structures, complex geometries, production volumes. Trusted by aerospace, automotive and industrial customers.
SLS is the benchmark process for functional prototypes and low-to-mid volume production requiring strength, durability and geometric freedom.
Unfused powder acts as self-supporting build medium. Undercuts, internal channels, interlocking assemblies — all achievable in a single build without support removal labour.
Parts are stacked in 3D across the full build volume, maximising packing density. More parts per build cycle drives your per-unit cost down significantly at volume.
PA12 SLS parts exhibit near-isotropic mechanical properties (X/Y/Z). Unlike FDM, strength does not degrade in the build direction — critical for load-bearing functional assemblies.
PA12, PA11 bio-based, glass-filled nylon, carbon-filled PA12, and flexible TPU. Materials that hold tight tolerances and survive real-world mechanical, thermal and chemical demands.
Lattice structures, conformal cooling channels, living hinges, snap-fits — SLS removes the design constraints imposed by injection moulding tooling and traditional subtractive processes.
From 1-off prototypes to 5,000+ production runs. No tooling cost, no MOQ. Seamlessly scale from prototype validation through to bridge and end-use production without re-tooling.
SLS is the go-to process wherever function, strength and geometric complexity must coexist.
Engineering-grade powders selected for mechanical performance, chemical resistance and regulatory compliance.
Lead Times: PA12 standard builds ship in 3–5 business days. Specialty materials (PA11, TPU, Alumide, CF variants) require 5–8 business days due to dedicated build scheduling and extended cooldown cycles. Contact us for urgent requirements.
SLS parts leave our facility clean, de-powdered and finished to your specification.
Removes surface powder residue, produces uniform matte finish. Standard on all PA12 parts.
Black, grey or custom colour immersion dyeing. Colour penetrates 0.5–1mm — surface resistant to scratching off.
Primer + topcoat system for colour-matched production appearance and UV stability.
Vibratory media finishing for smoother surface texture. Suitable for smaller batch parts with no fine features.
Heat-set or ultrasonic insert installation for threaded interfaces. M2–M12 range available in-house.
From CAD to finished parts in days — with full QA traceability at every step.
Submit STL/STEP via enquiry form. Receive detailed quote with DfAM feedback.
Parts nested at optimal packing density. Build parameters set per material and geometry.
CO₂ laser sinters powder layer by layer. Build chamber maintained at controlled temperature throughout.
Controlled cooldown prevents warpage. Parts carefully extracted and de-powdered via bead blasting.
Dimensional inspection, surface check, job card sign-off. Packed and dispatched with tracking.
We work with engineers, designers and procurement teams across Australia every day.
"I would highly recommend Pratik at 3D Printing — with his analytical mind he helped re-engineer a component for an electric scooter. The final design was cost effective, strong and an exact fit."
"Can't speak more highly of this Company. They overcame many difficulties through their tenacity and patience. I highly recommend this company for any 3D prototyping, design or development of your idea."
"Great service, quick turnaround — I needed parts scanned, a couple of design changes and printed. All done quickly, efficiently and A+ quality. Definitely recommend the team at 3D Prototyping."
"It was a pleasure dealing with 3D Prototyping. They are professional and their customer service is excellent. I would recommend these guys any time over any other players in this industry."
"This Company is good, efficient and easy to deal with. Their advice and knowledge around materials really helped us get what we needed. Great service provided. We will certainly use this company again."
Our engineers review every enquiry personally. Upload your CAD file for a detailed quote, or send a brief description and we'll respond within 2 business hours.
We accept STL, STEP, STP, OBJ, IGES, and 3MF. STL is preferred for most processes. If your file is in another format, upload what you have and our engineering team will assess it.
Standard lead times depend on the technology, part complexity, and production method. They range from 3–5 business days for prototypes to 8–10 weeks for injection-moulded parts. Accurate lead times are provided with every quote.
Build envelopes vary by system: SLA up to 800×800×550mm; SLS up to 360×360×420mm; MJF up to 380×380×280mm; SLM up to 450×450×500mm; FDM up to 1000×1000×1000mm. Oversized parts can be split and bonded — contact us for a feasibility review.
There is no minimum order quantity. We regularly produce single prototypes through to production runs of thousands of parts. Pricing scales with volume — ask us for a batch quote.
Yes. We offer media blasting, dyeing, priming, painting, sanding, vapour smoothing, and custom colour matching. All post-processing is handled in-house to maintain full quality control and traceability.
Absolutely. All client files and intellectual property are treated as strictly confidential. We are happy to sign a mutual NDA before receiving your files — just ask.
Yes. We ship to all states and territories across Australia with same-day dispatch for completed orders.
Australia’s production-grade 3D printing and manufacturing bureau. From concept to production — one team, one NDA. Delivering nationwide since 2008.
