Upload every part of your prototype kit and see one instant price. DC Additive Pros prints multi part kits in Rockville, Maryland: housings, brackets, gaskets, feet and fixtures, each in the material it needs. Each file is priced on its own, the parts add up to one job price, and you pay online to start. Made in USA, with no import duty.

Short version: drop up to 30 files or one ZIP below, pick a material and color for each part, set Kit copies if you need more than one kit, then pay. No request a quote step.
Upload your kit

How it works

  1. Upload your files: STL, STEP, 3MF or OBJ. Up to 30 files, or one ZIP with an optional parts list (file, qty, material, color).
  2. Pick a material and color for each part. Mix rigid and flexible parts in one kit.
  3. Need more than one complete kit? Set Kit copies. Every file's quantity is set to that number.
  4. See the price for each part and for the whole kit, instantly. Click Save quote for a written PDF if you need one.
  5. Pay online to start production. A real person reviews every file before it prints.

How kit pricing works

  • Each part is priced on its own from its size, material and print time, then added up into one job price.
  • One order minimum for the whole kit, not for each part. $20 for most materials; some materials have a higher minimum, shown in the tool.
  • Quantity discounts apply to copies of the same file only: 5% at 2 copies, 10% at 4, 15% at 10 and 20% at 25. The number of different parts in a kit never earns a discount.
  • Free US shipping is included. Sales tax is calculated at checkout.

Example: an 18 part kit in PETG and TPU 95A, one of each file.

Kits Pieces printed Discount Price
1 kit 18 0% $323
2 kits 36 5% on every file $613
4 kits 72 10% on every file $1,161
10 kits 180 15% on every file $2,739

Your price depends on your own files. The tool shows the exact price before you pay.

Good fits for a prototype kit

  • Product prototypes with several printed parts: enclosures, lids, brackets and mounts.
  • Assembly kits that mix rigid parts with TPU gaskets, bumpers and feet.
  • Pilot runs: 2 to 25 complete kits for testing, demos or a first customer batch.
  • Jigs and fixture sets for a production line.

Materials and print size

PLA, PETG, PCTG, PLA-CF, PETG-CF, PA12-CF (nylon), TPU 95A (flexible), TPU 90A (flexible), PEBA 90A (high rebound), PEBA 95A (high rebound), ABS / ASA, ESD-ABS, PPSU, PEEK, PEEK-CF10 (carbon fiber), PEI 9085 grade, PEKK-A. Some materials come in limited colors, shown in the tool.

Materials Largest part
ABS / ASA, ESD-ABS, PA12-CF (nylon), PPSU, PEI 9085 grade, PEEK, PEEK-CF10, PEKK-A 350 x 350 x 450 mm (13.8 x 13.8 x 17.7 in) on our high temperature printer
All other materials: PLA, PETG, PCTG, PLA-CF, PETG-CF, TPU, PEBA 400 x 400 x 400 mm (15.7 x 15.7 x 15.7 in)

Any orientation counts. A part over the limit for its material is flagged on its line with Scale to fit or a material change. The tool never shrinks a part on its own.

Good to know

  • Fit and function of untested prototypes are not guaranteed. Check your files before you pay.
  • Only upload files you have the right to have printed.
  • Staged deliveries are separate orders, each with its own order minimum.
  • No purchase orders and no local pickup. Every order ships to you.
  • We do not print firearms, firearm components or weapons of any kind.

Questions

Can I upload a ZIP of my whole kit?

Yes. Upload one ZIP or up to 30 separate STL, STEP, 3MF or OBJ files. Up to 60 MB per file and 200 MB unpacked per ZIP. A parts list inside the ZIP (CSV, TSV, TXT, MD or JSON with file, qty, material and color) fills in each matching part, and you can change any line before you pay.

Do you price each part separately?

Yes. Every file is priced on its own from its size, material and print time, then the parts are added up into one job price. We never price by the empty space between parts in a combined file, and one order minimum covers the whole kit, not each part.

Can parts in one kit use different materials and colors?

Yes. Choose a material and color for each part, for example PETG for housings and TPU 95A for gaskets and feet. The tool shows the price for each part and for the whole kit.

How do quantity discounts work on a kit?

Discounts apply to copies of the same file only: 5% at 2 copies, 10% at 4, 15% at 10 and 20% at 25. An 18 part kit with one of each file gets no discount, because 18 different parts are not 18 copies of one part. Order 2 complete kits and every file is printed twice, so every file gets 5%.

How do I order more than one complete kit?

Upload all of the files, then set Kit copies to the number of kits you need. Every file's quantity is set to that number, and the same file discount applies to each file. You can still change any single line before you pay.

Is the price on screen the final price?

Yes. The price the tool shows is the price you pay at checkout, with free US shipping included. Sales tax is calculated at checkout. There is no request a quote step and no price cap; only physical limits such as print size and material stop an order.

Can I get a written quote for my purchasing team?

Yes. Click Save quote for a printable PDF with a quote ID, the date, a price for each part, shipping, lead time and terms, plus a link that reloads the same parts and rechecks the price. The quote is valid 14 days.

What is the largest part you can print?

ABS, ASA, ESD-ABS, PA12-CF nylon, PPSU, PEI 9085 grade, PEEK, PEEK-CF10 and PEKK-A print up to 350 x 350 x 450 mm on our high temperature printer. All other materials print up to 400 x 400 x 400 mm. Any orientation counts. A part over the limit is flagged with Scale to fit or a material change; the tool never shrinks a part on its own.

How fast will my kit ship?

3 to 7 business days is typical. Rush production is 2 to 3 business days for 25% more. Large kits with long print times may need the full window.

Do you test fit my prototype?

We print the geometry you submit and review every file before it prints, but fit and function of untested prototypes are not guaranteed. Check clearances and tolerances in your files before you pay.
