Expert 3D Printing & Finishing Specialist Desired

HIGH-QUALITY 3D PRINTING + PROFESSIONAL MASTER FINISHING FOR VACUUM CASTING
NOT JUST 3D PRINTING — COMPLETE MASTER PATTERN FINISHING REQUIRED

I am looking for an experienced professional 3D printing and model-finishing specialist to produce small and very small precision parts that will be used as master patterns for vacuum casting.

The requirement is not simply to 3D print the parts. The printed parts must be professionally post-processed and finished to achieve high-quality, smooth, refined master patterns suitable for mould-making and vacuum casting.

Required Work

The complete process may include:

High-resolution / precision 3D printing
Excellent reproduction of very fine details
Accurate dimensional reproduction
Careful support removal
Precision sanding
Surface preparation
Professional priming
Fine sanding and rubbing
Buffing
Polishing
Gloss finishing
Clear coating
Final polishing/buffing where required
Required Final Quality

The finished masters must have a very smooth, clean and highly refined surface, with:

Minimal or no visible layer lines
No obvious support marks
No sanding scratches
No pinholes or unwanted surface imperfections
Clean and sharp details
Smooth glossy surfaces where required
Professional clear-coat finish
Excellent overall surface quality suitable for vacuum casting master patterns

Since these are small and miniature parts, experience with delicate components and preservation of fine details during post-processing is essential.

Preferred Experience

Preference will be given to freelancers experienced in:

High-resolution resin 3D printing
Miniature/precision parts
Professional model finishing
Master pattern preparation
Silicone mould making
Vacuum casting
Resin casting or similar mould/casting applications
Please Include in Your Bid
Your 3D printing technology and printer.
Materials/resins you use.
Your experience with small/miniature precision parts.
Your complete post-processing/finishing procedure.
Experience preparing masters for vacuum casting or mould making.
Before-and-after photographs of your previous 3D prints showing the final finished surface.
Estimated turnaround time.
Your pricing.
SAMPLE / TRIAL

A small number of parts may initially be provided as sample masters to evaluate printing accuracy, detail reproduction, surface finishing and overall quality.

If the samples meet the required standard, additional parts may follow.

IMPORTANT: I am looking for someone who can deliver the COMPLETE FINISHED MASTER, not an unfinished 3D print.

Printing Quality + Surface Finishing + Final Master Quality are all equally important.
