What can you generate a 3D model from?

From a photo of the object (1–4 photos from different angles), from a sketch or technical drawing, from a text description (e.g. 'a medieval sword with ornaments'), or as a reconstruction of an existing 3D object from photos.

Who is this service for?

For makers and 3D printing enthusiasts, designers, gaming/film studios for prototypes, architects for visualizations, marketing teams for presentation models, and inventors for rapid prototyping of ideas.

AI generation + manual cleanup

From sketch to a custom 3D model

Q: What is an AI 3D model?

An AI 3D model is a 3D object generated by artificial intelligence based on a photo, sketch or text description. Specialized AI platforms create a mesh, which we then clean up manually and prepare for 3D printing or other uses.

Q: What files do I receive?

You receive an STL file (the universal format for 3D printing) and an OBJ with a UV map if the Optimized package is ordered. The files are suitable for all 3D printers (FDM, SLA), Blender, Maya, ZBrush and online platforms.

Q: How long does production take?

You receive the Basic STL in 24–48 hours. The Optimized model with manual cleanup in 48–72 hours. With 3D printing added, total production takes 7–10 days.

Q: Can I use the model commercially?

Yes. All models we generate for you are your property and can be used commercially (sales, printing, presentations). However, reproducing protected objects or people requires the appropriate permission.

Send a sketch or photo — we'll create a print-ready STL model

Turn any sketch, photo or text description into a print-ready 3D model. We use specialized AI platforms, then clean up and optimize the model manually for 3D printing or further use. You receive the STL/OBJ file by email within 24–72 hours.

From sketch to 3D model — a set of custom 3D models (fantasy and sci-fi characters) printed from AI-generated STL models in the 3DShop.si workshop

Workshop example — RUNAH set

5 AI-generated characters for RUNAH collectors

A set of five fantasy and sci-fi figurines, AI-generated from various inputs — concept images, descriptions and references of existing characters. Each model was cleaned up manually, optimized for 3D printing and painted in the workshop. Around 6 hours of manual work in total; AI covered 70% of the geometry, 30% was cleanup and retopology.

Package:Optimized STL + 3D printing (€39 per figure) Production:10 days Size:~6–8 cm

The workflow in practice — from AI mesh to a printed piece

Every AI 3D model we make goes through three stages: AI mesh generation, manual cleanup with print optimization and (optionally) 3D printing + painting. Below are a few real examples from the workshop — comparisons of bare meshes and final renders, single-render examples, and a photo from production in action.

From sketch to 3D model — an STL model of a soldier ready for 3D printing, raw mesh before manual cleanup — **1 · AI mesh (raw)** Raw 3D model straight from AI generation — good geometry, no textures, minor artifacts to clean up.

3D render of the finished soldier in a Santa-red outfit with a rifle — after cleanup, textures and rendering — **2 · Final render** After cleanup, textures and lighting setup. STL ready for 3D printing, or a render for marketing.

AI-generated STL mesh of a cyberpunk woman in a coat — raw mesh model — **1 · AI mesh (raw)** A cyberpunk character with a coat and accessories — a complex silhouette, an example where AI covers a lot of detail.

Final render of the cyberpunk character with green hair in a green coat — after texturing — **2 · Final render** Skin, hair, coat material and accessory textures — ready for production or print.

AI-generated STL mesh of an anthropomorphic pig-soldier in tactical gear with a rifle — raw 3D mesh model before texturing — **1 · AI mesh (raw)** An anthropomorphic character generated from a text description — pig anatomy combined with human military gear.

Final 3D render of the anthropomorphic pig-soldier with a helmet frame and rifle — after texturing, materials and lighting setup — **2 · Final render** After textures, skin, gear materials and lighting — ready for 3D printing or marketing.

A 3D model from a sketch ready for 3D printing — batch production on a 3D printer in the 3DShop.si workshop — **3 · Production** Batch production of AI-generated badges on our 3D printer — from a digital STL to a physical piece.

Process

How do we turn a sketch into a 3D model?

Do you have a sketch, drawing or photo and want a print-ready 3D model from it? At 3DShop.si we are designers of custom statues and 3D models. From your template we create an accurate 3D model in STL or OBJ format, ready for 3D printing.

The process from sketch to 3D model runs in three steps:

You send a template — a sketch, drawing, photo or description of the idea.
Modeling — we create the 3D model using AI tools and manual refinement.
Preview and delivery — we send a preview, and after approval you receive the STL/OBJ file.

The model is suitable for FDM and resin 3D printers. If you don't have your own printer, we can also print and paint it for you.

Specialized: from sketch to 3D model — everything about converting a drawing or sketch into a print-ready STL model.

What we can generate from

Input materials

Photo

1–4 photos of the object from different angles. More angles = better 3D reconstruction.

Sketch or drawing

A hand sketch, technical drawing or concept art. Black-and-white is fine too.

Text description

"A medieval sword with ornaments", "a miniature house with a chimney" — AI generates from the description.

Existing model

Cleanup or remix of an existing STL/OBJ — using AI for better topology.

Who it's for

Most common uses

Makers and hobbyists

Rapid prototyping of ideas, custom figurines for miniature games (D&D, Warhammer), parts for RC modeling.

Designers

A concept-to-3D pipeline without manual modeling in Blender/ZBrush. Idea → AI → cleanup → ready-to-print.

Architects

3D reconstructions of existing buildings from photos or plans for visualization and scale models.

Marketing

Product presentation models, scale prototypes, custom packaging ideas before a CAD designer.

Film production

Rapid props and concept models for pre-vis, storyboards and set design.

Inventors

Turning an idea on paper into a physical prototype — modeling and printing in one package.

Frequently asked questions

Most common questions

How do I turn a sketch into a 3D model?

You send us a sketch, drawing or photo. From it we create a 3D model (STL or OBJ) using AI tools and manual refinement. You receive a preview, and after approval the print-ready file.

In which format do I receive the 3D model?

You receive the model in STL or OBJ format — both are suitable for most 3D printers and 3D software. On request we also prepare other formats.

How much does making a 3D model from a sketch cost?

Making a 3D model starts at €15, depending on complexity. For an exact price, send your sketch or description to info@3dshop.si.

Can you also print the model?

Yes. In addition to making the 3D model, we also offer 3D printing and hand painting. With printing added, the price starts at €39.

What is an AI 3D model?

A 3D object generated by artificial intelligence based on a photo, sketch or text description. We use specialized AI platforms, then clean up and optimize the model manually.

What files do I receive?

An STL file (the universal format for 3D printing). With the Optimized package you also get an OBJ with a UV map. The files are suitable for FDM/SLA printers, Blender, Maya, ZBrush.

How long does production take?

Basic STL in 24–48 hours, Optimized in 48–72 hours, with printing added a total of 7–10 days.

Can I use the model commercially?

Yes. All models are your property and can be used commercially. Reproducing protected objects or people requires the appropriate permission.

Can missing details be completed?

Yes, with the Optimized package we complete missing details (the back of the object, texture, minor artifacts). Very demanding fixes are arranged individually.

What if the result isn't suitable?

We offer up to 2 free regenerations. If the AI can't achieve a satisfactory result, we refund your payment (less €5 for the work).
