How to Order with SLA Bulk Upload

Our SLA Bulk Upload tool lets you upload multiple 3D models at once and get instant pricing for your entire batch. As a result, you can quote and order large multi-part projects in minutes. In addition, this tool supports STL, STEP, OBJ, and IGES formats. For single-part orders, use our standard SLA configurator instead.

1
Upload Your Files
First, drag and drop multiple 3D model files into the upload area below. Then, wait until all files finish uploading. In addition, make sure your models meet the Design Guide specifications.

2
Configure & Analyse
For each model, select your preferred material, colour, layer height, infill, and quantity. After that, click the Analyse button. As a result, the system calculates pricing for every model in the batch.
3
Add to Cart & Checkout
Finally, once analysis is complete, review your prices. Then, click Add to Cart to proceed to checkout. Consequently, your entire batch order is placed in one transaction.
Not sure which settings to choose? In that case, visit our Settings Guide for recommendations. Additionally, check the Material Guide for comparisons. Similarly, for FDM thermoplastic bulk orders, use the FDM Bulk Upload page.

Upload Your 3D Models

Simply drag and drop files below. Then, configure each part independently. After that, click Analyse to generate prices for all models at once.

SLA Bulk Upload — 3 Photopolymer Resins Available

All 3 professional-grade SLA resins are available for bulk orders. Moreover, each part in a batch can use a different resin type. For detailed specs, see the Material Guide.

SLA Bulk Upload Standard Resin material
Standard Resin
36–53 MPa · Ultra-Fine Detail
Best surface detail in our lineup. 0.025 mm layer height, features down to 0.1 mm. For miniatures, dental mockups, and jewellery masters.
Tough Resin impact resistant SLA 3D printed parts
Tough Resin
36–53 MPa · 14–25% Elongation
Impact-resistant photopolymer. Bridges brittle resin and engineering plastics. For snap-fits, enclosures, and functional prototypes.
Clear Resin transparent SLA 3D printed optical parts
Clear Resin
36–53 MPa · Near-Optical Clarity
Transparent photopolymer with light transmission. For lenses, light guides, transparent enclosures, and fluidic prototypes.

SLA Layer Heights

In short, smaller layers produce finer detail. However, they increase print time. See the Settings Guide.

Infill — 100% Solid

Unlike FDM, all SLA parts are printed at 100% solid infill. As a result, every part has optimal strength and surface quality.

Therefore, there is no infill setting to configure for SLA orders. Additionally, all parts undergo UV post-curing for maximum mechanical performance.
