3D printed investor samples — presentation-quality parts that look and feel like the final product.
Investor meetings are won with tangible products, not slide decks. Our 3D printing service produces presentation-quality samples that demonstrate your product vision in physical form — the weight, the finish, the mechanism, the feel. When an investor picks up your prototype and it feels like a finished product, your credibility multiplies.
Challenges we solve
What investor samples teams need from a 3D printing service
Making a prototype look like a finished product
Investors evaluate your product — and your judgment — based on what you put in their hands. SLA resin parts with post-processing deliver surfaces that rival injection molding. We sand, prime, and paint to your brand spec so the sample represents the product, not the manufacturing process.
Producing samples on pitch timelines
Investor meetings get confirmed with days of notice. We produce presentation samples in 2–5 business days. For NYC-based founders, same-day pickup is available for files approved before 3:30 PM. Your pitch should never be held up by parts.
Demonstrating functional mechanisms
A static model tells one story. A working mechanism tells a better one. We produce multi-part assemblies with functioning hinges, snap-fits, buttons, and moving components so you can demonstrate how the product actually works.
Producing multiple samples for different meetings
You may need 5–10 identical samples for parallel meetings, accelerator events, and leave-behinds. We produce multiple units with consistent quality so every investor sees the same product.
Materials
Materials for investor samples
Standard Resin on SLA delivers the smoothest surface finish (2 Ra μm) — ideal for samples that will be handled, photographed, and scrutinized up close. MJF Nylon PA12 produces a professional matte finish for products targeting injection-molded nylon. For painted or branded samples, we recommend SLA followed by sanding, priming, and painting to your brand colors.
Standard Resin
SLA · Shore D 78
Smooth surface, fine detail. Good for visual prototypes and concept models.
Tough 2K
SLA · Shore D 76
ABS-like toughness with SLA detail. Functional prototypes that need impact resistance.
Nylon PA12
MJF · Shore D 73
Strong, lightweight, chemical resistant. The standard for functional end-use parts. Excellent fatigue resistance and consistent mechanical properties.
PLA
FDM · Shore D 81
General purpose, biodegradable. Rigid, good surface finish. Not heat or UV resistant.

How it works
Your project, step by step
Upload files
Send your CAD files with notes on finish, color, and presentation requirements. Include photos or renders of the intended final product.
Material & finish
We recommend the material and post-processing that will best represent your production intent — surface finish, color, weight, and feel.
Print & finish
Parts are printed, then sanded, primed, and painted as needed to presentation quality. Working mechanisms are assembled and tested.
QA
Every sample is inspected for surface quality, fit, finish, and function before shipping.
Ship
Samples packed for safe transit and shipped on your timeline. NYC founders get same-day pickup.
FAQ
Frequently asked questions
Can you paint or brand the samples?
Yes. We sand, prime, and paint to your brand colors. We can also apply decals, logos, and surface textures to match your production intent.
How many samples should I order?
We recommend 3–5 samples minimum: one for your primary pitch, one or two for parallel meetings, and one as a backup. For demo days and accelerators, order 5–10.
Can the samples include working mechanisms?
Yes. We regularly produce multi-part assemblies with functioning hinges, buttons, snap-fits, and sliding mechanisms. If the product moves, the sample should move.
How fast can I get samples for an unexpected meeting?
FDM parts ship in as fast as 1 business day. SLA in 2–3 business days. For NYC founders, same-day pickup is available for files approved before 3:30 PM ET.
