## iFactory3D

iFactory3D GmbH brings automated volume production to additive manufacturing. Instead of the fixed build plate found on conventional desktop printers, the company's One Pro machine extrudes onto a continuous belt at a 45-degree angle. Because finished parts simply travel off the end of the belt, print length is effectively unlimited, complex geometry can be built with far less support material, and the machine can keep running unattended — the core requirement for serial production rather than one-off prints.

Beyond the hardware, iFactory3D sells complete application packages. These include a PETG filament and care bundle, a turnkey solution for 3D-printed orthopedic insoles (scanner, software, printer and material), and a system for producing meter-long polymer extrusion profiles for prototypes and custom window, furniture or cladding parts. The company also runs its own print service, quoting series plastic parts produced faster and more cheaply than injection molding, in runs from a single piece up to 20,000 units.

The company targets industrial and commercial buyers — automotive, mechanical engineering, hospitality and medical applications among them — and backs deployments with on-site consulting, individual test prints, onboarding, training and personal support. Its positioning is that agile, localized, individualized manufacturing is the future, and belt printing is how additive technology gets there.

**Pricing & Plans:** Paid / quotation-based. Hardware, filament bundles, application packages (insoles, extrusion profiles) and the print service are all quoted per project. The published print service rate starts at about €3.90 per print hour. Consult with iFactory3D for current machine and package pricing.

- **Belt (conveyor) printing architecture:** The One Pro prints onto a moving belt rather than a fixed plate, so objects travel continuously and print length is practically unlimited — including multi-meter profiles.
- **45-degree print angle:** Printing at an incline allows complex overhangs with significantly less support material, improving both part quality and material efficiency.
- **Unattended serial production:** Finished parts leave the build area automatically, so the printer can run batches back-to-back without an operator clearing the bed between jobs.
- **Turnkey application packages:** Ready-made bundles for orthopedic insoles (scanner, software, printer, material) and for meter-long extrusion profiles for prototyping and custom parts.
- **Print service up to 20,000 units:** iFactory3D will produce series plastic parts on request, from 1 to 20,000 pieces in a few days, with pricing from about €3.90 per print hour.

**Strengths:** Effectively unlimited print length via belt technology; Far less support material thanks to the 45-degree print angle; Suited to real serial production, not just single prototypes; Complete packages with consultation, training and support

**Limitations:** Machine and package pricing is quote-only, no public list price; Belt printing requires rethinking part orientation and workflow vs. a normal bed-slinger; Hardware purchase is a significant investment aimed at businesses rather than hobbyists

## Spline

Spline brings 3D design into the browser so designers, developers and marketers can build interactive 3D without a heavyweight desktop pipeline. The editor covers primitives, booleans and sculpting, plus 3D generation, layered materials, lighting and post-processing. Animation and interaction are handled through states, keyframes, events and physics, and the whole file runs with real-time performance.

A standout feature is agent collaboration: you can connect assistants such as Claude, ChatGPT, Cursor or Codex through Spline MCP so an agent can read and write to the live scene, then hand it back to your team for refinement in the very same file. Because everything the agent produces is a regular Spline object, teammates can select, restyle, animate or undo it by hand at any point.

Publishing targets the modern web and mobile stacks. You can share a link, embed a viewer or export code for web (WebGPU/WebGL), add a native SwiftUI or Metal view for Apple apps, or build for Android with Vulkan and Jetpack Compose. Spline is used for interactive product design, brand and marketing pages, immersive experiences, gamified sites and education.

**Pricing & Plans:** Spline offers a free tier to start building in 3D, with paid plans for individuals and teams and a dedicated Enterprise offering. Exact seat and feature limits per tier are listed on the Spline pricing page.

- **In-browser 3D editor:** Model with primitives, booleans and sculpting, and use 3D generation to create objects from prompts.
- **Materials, lighting and post-processing:** Apply layered materials, lights and post-processing effects to give scenes a polished, production-ready look.
- **Animation and interaction:** Build interactivity using states, keyframes, events and physics so scenes respond to scroll, hover and other triggers.
- **Agent collaboration over MCP:** Connect AI coding agents to read, write and frame the live scene, then refine the same file by hand with your team.
- **Ship to web, iOS and Android:** Publish a link, embed a viewer, export code for the web, or create native Apple and Android views and builds.

**Strengths:** Runs entirely in the browser, so there is no heavy install or setup barrier; Real-time collaboration and agent workflows keep designers and developers in one shared file; One scene publishes to web, iOS and Android with platform-native renderers; Broad feature set spanning modeling, materials, animation, physics and interaction

**Limitations:** Advanced 3D work may still require a learning curve for newcomers; Performance and export options depend on the device and platform you target; Team and enterprise capabilities sit behind paid tiers
