MJF offers near-unrestricted design freedom with tighter tolerances than SLS. Follow these guidelines for the best results.
MJF's voxel-level precision and consistent build chamber temperature enable tighter clearances and finer features than SLS. Our engineers review all files for orientation and nesting optimization before printing.
We print on HP Jet Fusion machines - the industry standard for MJF. HP-certified materials, validated processes, and production-proven consistency that standalone prototyping shops cannot match.
MJF's speed advantage grows with volume. We optimize every build for maximum nesting density, passing those savings to you. Order 50 parts and pay significantly less per unit than 5 parts.
Upload your STL and receive instant pricing based on material volume, build density, and finish. No waiting, no negotiation, no hidden fees. What you see is what you pay.
Every MJF order is reviewed by our engineers for orientation and nesting optimization before printing. We maximize build density to reduce your cost per part without any extra effort on your side.
MJF's inkjet-based process delivers more consistent properties across the build volume than SLS. When you reorder, parts from batch 10 match batch 1 - critical for production and assembly use.
Bead blasting, dyeing, painting, waterproofing, and insert installation handled entirely by Partwork. Receive production-ready, finished parts - not raw prints.
100% quality assurance with full batch traceability. HP-certified material datasheets, build logs, and dimensional inspection reports available for every order on request.
Manage MJF alongside SLS, SLA, FDM, CNC machining, and sheet metal fabrication from a single Partwork dashboard. Prototype in FDM, refine in SLA, and produce in MJF - all without changing platforms.
| Feature | SLS 3D Printing | MJF 3D Printing |
|---|---|---|
| Technology | CO₂ laser traces each layer point-by-point | Inkjet arrays fuse entire layer simultaneously |
| Build Speed | Slower - laser traces each cross-section | Up to 10× faster for dense production builds |
| Surface Finish (as-printed) | Ra 6-12µm (matte, grainy) | Ra 4-6µm (smoother, more uniform) |
| Dimensional Accuracy | ±0.3mm or ±0.3% | ±0.2mm or ±0.2% (more consistent) |
| Edge Sharpness | Slightly rounded edges (laser spot size) | Sharper edges (detailing agent precision) |
| Part Color (as-printed) | White / light grey | Uniform dark grey (aesthetically cleaner) |
| Build Volume Consistency | Properties vary slightly by build position | Highly consistent across full build volume |
| Minimum Wall Thickness | 0.7mm | 0.5mm (thinner walls achievable) |
| Support Structures | None required | None required |
| Material Options | PA12, PA11, TPU, PA12-GF, wider range | PA12, PA11, TPU (focused material set) |

| Cost at Medium Volume (50-500 parts) | Moderate | More economical - faster build, higher density |
| Best Use Case | Complex prototypes, wide material variety | Consistent production runs, fine features at scale |
MJF delivers its strongest economics from 50 units upward. A fully optimized build spreads machine cost across more parts, making MJF the most cost-effective polymer 3D printing process for production quantities. Beyond 2000 units, Partwork will recommend injection moulding - we'll help you evaluate the crossover point based on your part geometry and annual volumes.
Answers to common questions about mjf 3d printing in india — smoother than sls, production-ready in 3 days.
Both are powder bed fusion processes using Nylon powder with no support structures needed. MJF uses inkjet arrays to deposit fusing agents across the entire layer simultaneously, then fuses with infrared - making it 5-10× faster than SLS's single laser point. MJF also produces finer surface finish (Ra 4-6µm vs 6-12µm), sharper edges, more consistent properties across the build volume, and tighter dimensional accuracy (±0.2mm vs ±0.3mm).
MJF is better for production volumes, finer surface finish, and tighter tolerances. SLS is better for very low volumes (1-20 parts where SLS cost per part is lower), a wider range of specialty materials like glass-filled Nylon, and lighter-colored as-printed parts. For most functional prototyping and production applications above 20 units, MJF offers better economics and quality.
MJF parts appear dark grey or near-black because the fusing agent contains carbon black, which absorbs infrared energy for sintering. This gives MJF parts a consistent, aesthetically clean dark tone that many designers prefer over SLS's white/grey powder finish. Parts can be dyed or painted in any color post-print.
No. Like SLS, MJF uses surrounding unfused powder to support the part during printing. This enables complete geometric freedom - overhangs, undercuts, internal channels, and interlocking assemblies with no support marks, no support removal, and no design restrictions.
MJF achieves ±0.2mm or ±0.2% dimensional accuracy (whichever is greater). This is better than SLS (±0.3mm) and makes MJF suitable for functional assemblies, snap fits, and parts with close clearances. For features requiring tighter tolerances, light post-machining is recommended.
Yes. Hinged assemblies, rotating joints, and interlocking mechanisms can be printed fully assembled in a single MJF build, provided there is at least 0.4mm clearance between moving surfaces. MJF's tighter accuracy (vs SLS) makes assembled mechanisms more reliable straight from print.
At low volumes (1-20 parts), MJF can be slightly more expensive than SLS per part. However, from 50 units upward, MJF becomes increasingly cost-competitive due to its faster build speed and higher nesting density. For production batches of 100-500 parts, MJF typically offers lower cost per part than SLS.
Standard PA12 and PA11 parts are dispatched in 3-5 days. TPU flexible parts take 4-6 days due to additional handling. Parts with dyeing take 5-7 days. Production batches of 100+ units take 6-10 days with full build optimization.
As-printed MJF parts are uniform dark grey. Post-print dyeing is available in black (deepening the natural tone), blue, red, and custom colors. Painting in any RAL or Pantone color is available for any volume. Dyeing is more economical than painting for production batches.
As-printed MJF parts are porous and not inherently waterproof. Waterproofing via epoxy or polyurethane impregnation is available as a post-processing option. Waterproofed MJF PA12 parts are suitable for fluid-contact, outdoor, and wash-down environments.
Yes, MJF is widely regarded as the most production-ready polymer 3D printing technology. HP-certified material properties, consistent cross-batch repeatability, and fast build speeds make MJF parts directly suitable for low-to-medium volume production in automotive, medical, electronics, and consumer product industries.
We accept STL, OBJ, and 3MF files. STEP/STP files are also accepted and converted. Ensure your model is manifold (watertight) with consistent outward normals. For production batches, 3MF format is preferred as it preserves scale and orientation metadata.
