Professional custom 3D printing for makers, enthusiasts and businesses. We manufacture custom parts, prototypes and one-off projects from your 3D models.
We print custom parts.
From automotive components to household items and custom gifts. If you have a 3D model, we can manufacture it.
Automotive Parts
Clips, brackets, trim pieces, and functional components for restoration and custom builds. Printed in materials that handle heat and daily use.
Functional Parts
Gears, brackets, mounts, and mechanical components for real-world use. Strong, dimensionally accurate prints for applications that need to work.
Die-cast Modifications
Body kits, wheel swaps, and custom accessories for die-cast collectors. Precise, clean prints that match your collection's scale and finish.
Prototypes
Test fit, form, and function before committing to expensive tooling. Turn your CAD designs into physical parts quickly and affordably.
Household & Hobby
Custom organisers, replacement household parts, hobby accessories, and practical prints for everyday use around the home and workshop.
Custom Gifts
Personalised keepsakes, trophies, and one-off creations. Thoughtful, made-to-order items manufactured with attention to every detail.
From idea to finished part
Tell us what you need
Upload a file, send a photo, or describe your idea. Choose the path that best fits your situation. We meet you where you are.
We review and quote
We assess your project within 24 hours. You'll get a clear, itemised quote with material recommendations and timeline.
We manufacture
Once confirmed, your job enters production. Professional FDM printers run with quality monitoring. We keep you updated throughout.
Quality check and deliver
Every part is inspected, finished, and carefully packaged. Island-wide delivery or pickup from our Colombo facility. Your choice.
The right material for your project.
We'll help you choose. From everyday PLA to carbon fibre composites — there's a material that fits your application.
PLA
The workhorse of desktop manufacturing. Stiff, easy to print, and available in hundreds of colours. Ideal for prototypes, display models, and low-stress applications.
Strength
Medium
Heat Resistance
Up to 55°C
Outdoor Use
Not recommended
Best For
Prototypes, décor, gifts
Shrinkage: ~0.2–0.5%
PETG
The sweet spot between ease and performance. Stronger than PLA with better heat resistance and flexibility. Food-safe variants available for kitchen applications.
Strength
High
Heat Resistance
Up to 75°C
Outdoor Use
Good
Best For
Functional parts, enclosures
Shrinkage: ~0.3–0.8%
ABS
Industry-standard thermoplastic. Exceptional impact resistance and durability. Used in automotive interiors, appliance housings, and LEGO bricks.
Strength
Very High
Heat Resistance
Up to 95°C
Outdoor Use
Good with coating
Best For
Automotive, tough parts
Shrinkage: ~1.0–1.5%
ASA
ABS's outdoor-ready sibling. Superior UV resistance and weatherability make ASA the definitive choice for exterior automotive trim, signage, and outdoor enclosures.

Shrinkage: ~0.8–1.2%
TPU
Flexible, rubber-like filament ranging from 85A to 95A shore hardness. Produces gaskets, phone cases, vibration dampeners, and wearable devices.
Strength
Medium–High
Heat Resistance
Up to 60°C
Outdoor Use
Moderate
Best For
Flexible parts, wearables
Shrinkage: ~0.5–1.0%
Carbon Fiber Composite
Engineering-grade filament reinforced with chopped carbon fibre. Exceptional stiffness-to-weight ratio and dimensional stability. For when aluminium is overkill but PLA isn't enough.
Strength

Best For
Structural, drone, jigs
Shrinkage: ~0.1–0.3%
A workshop, not a factory.
Zenki Lab started with a real problem: restoring classic Toyota vehicles when original replacement parts were no longer available. Rather than giving up, we manufactured our own. That same capability is now offered to anyone who needs custom printed parts.
We're not trying to be a print farm. Every project, whether a single bracket or a batch of 50 parts, gets the same level of care we'd expect for our own builds. Honest advice, clear communication, and parts that fit right the first time.
Questions? We've got answers.
Clear, honest answers about how we work.
We accept STL, OBJ, 3MF, and STEP files. For assemblies, ZIP archives containing multiple files are recommended. Maximum single file size is 250 MB. For larger projects, contact us directly.
Our current service is printing customer-provided 3D models. If you have a 3D file, we can manufacture it. If you only have an idea or a broken part with no model, contact us. CAD modelling and reverse engineering may become available in the future, but are not currently offered.
Our material lineup includes PLA, PETG, ABS, ASA, and TPU. Carbon-fibre-reinforced composites are available on a per-project basis. Each material has different properties: strength, flexibility, heat resistance, and UV stability. We'll help you choose the right one for your project.
Production time depends on part size, complexity, and material. Small parts (keychains, brackets) typically ship within 2–3 business days. Larger projects may take 5–10 business days. You'll receive an estimated timeline with your quotation.
Yes. Standard post-processing includes support removal and light sanding. Additional services include vapour smoothing (ABS/ASA), primer application, painting, and clear-coat finishing. These are available at quoted rates. Tell us about your finishing requirements when you submit your project.
Single-colour prints are our standard. Multi-colour printing is possible for select projects using manual filament changes. Note that multi-colour adds print time and cost. Contact us with your specific requirements.
We provide basic printability feedback and can make minor file repairs to ensure a successful print. Full design changes or modifications to your model are not currently offered. For best results, provide a ready-to-print STL file.
We currently ship within Sri Lanka with island-wide delivery. International shipping may be available upon request for select projects. Contact us to discuss.
Pricing is based on material volume, print time, post-processing requirements, and quantity. You'll receive a transparent, itemised quote before any work begins. Rush orders and complex geometries may affect pricing.
No. We manufacture single one-off prints as well as small batch runs. Per-unit cost typically decreases with quantity. We're happy to discuss volume pricing for recurring orders.
Tell us what you need. We'll handle the rest.
Upload your STL files, describe your project, and we'll review and respond with a detailed quote within 24 hours.
