6 processes, one point of contact

From review mockups to small-batch production, we combine the processes you need into one proposal.

01

3D Printing

With both FDM and SLA in-house, you can choose the material and precision that fit your purpose. Complex internal structures and undercuts print directly without molds.

Same day–24H PLA · ABS · Resin
A

FDM Printing

Ideal for practical use — durable functional parts, jigs and fixtures.

B

SLA Printing

Smooth surfaces and fine detail, ideal for design review and exhibition mockups.

C

Post-processing

Support removal, sanding and painting can follow seamlessly.

02

Prototyping

From simple form-check mockups to functional prototypes you can assemble and operate, we build to your development stage.

Design review included
A

Design Review

We check your drawings from a manufacturing perspective first and flag potential issues in advance.

B

Functional Test Prototypes

Built with precision suitable for assembly, fastening and operation testing.

C

Rapid Iteration

After the first prototype, we quickly turn around 2nd and 3rd revisions with updated dimensions and shapes.

03

Injection Molding

From low-volume trial shots to production molds, we propose mold specs that match your expected volume.

Low volume to mass production
A

Mold Design

Based on your product geometry and expected volume, we recommend either a prototype mold or a production mold.

B

Trial Molding

We shoot samples before full production to verify dimensions and appearance.

C

Production Molding

We run injection molding in the quantity you need with finalized specs.

04

CNC Machining

Precision machining of aluminum, plastics and more. We reliably handle parts with tight tolerances.

Tolerance ±0.05mm
A

Precision Machining

Machined to drawing tolerances; parts requiring assembly are inspected together with their mating parts.

B

Material Selection

We help you choose the right material for the application — aluminum, POM, acrylic and more.

C

Surface Finishing

We also advise on finishing such as anodizing and sanding.

05

Laser Cutting

Precision cutting of acrylic, wood and thin sheet metal, with logo or text engraving in the same pass if needed.

Engraving in one pass
A

Precision Cutting

Clean cuts even for fine patterns and thin bridge shapes.

B

Engraving · Marking

Logos, text, QR codes and more can be engraved while cutting.

C

Small-batch Production

Well suited for small runs of exhibition pieces, signage and packaging prototypes.

06

Models · Dioramas · 3D Video

We turn products and spaces into tangible results — from architectural and exhibition models to collectible miniatures and promotional 3D video, working with you from the planning stage.

Painting & assembly included From 1 unit
A

Model Making

Architectural, product and exhibition models built to scale and finished with painting.

B

Diorama Production

Scene-based dioramas with backgrounds, props and lighting, from planning to production.

C

Miniature Production

Precise miniatures for collection or promotion, such as characters and scaled-down products.

D

Clicker Production

Merchandise and promotional clickers, starting from small quantities.

E

3D Video

3D animation videos for product introductions, operation demos and exhibitions.
