Friday 7pm in Rockville, Maryland. Order 847 going out the door to a research lab in San Diego.

4 polymer printers. 1240 square feet. One operator. No employees, no warehouse, no overseas supply chain.

Started in 2023 with one machine and a single eBay listing.

Tonight's shipments: peptide vial racks for biotechs, battery holders for electricians, custom lab fixtures for NIH researchers, and a rush order to Alaska.

This is American manufacturing in 2026. Small shop. Long night. Real orders.

DC Additive Pros, Rockville MD. Same-day quotes.

Supports have always been the tax you pay for steep overhangs on an FDM printer: extra plastic, ugly scars, and that annoying snap-off cleanup. Somebody just figured out how to skip almost all of it, and no, it isn't a fancier printer. It's a different way of drawing the toolpath, and the clue is hiding in plain sight (think ripples spreading across a pond). Full story's on the blog, link in bio. What's the gnarliest overhang you've ever fought with a wall of supports? #3DPrinting #FDM

A federal lab just taught a 3D printer's laser to stir molten metal like cake batter, and it makes a notoriously impossible class of alloys printable, with zero new hardware. The how (and why a dentist's X-ray machine got involved) is the full story on the blog, link in bio. If metal limits vanished tomorrow, what's the first part you'd print? #3DPrinting

@DabsMalone I didn't know there was another way. Some of the best deals occur after some good trash talking. ✊🤝

[DC Additive Pros @DCAdditivePros]

Turns out the sawdust your shop sweeps into the trash every day might belong inside your 3D printer instead. A new study put wood filled PLA on the test bench, and one property jumps up while another quietly drops (the trade off is not the one most folks assume). Full story is on the blog, link in bio. Would you trust wood filled PLA for a part that actually has to do a job, or keep it just for the looks? #3Dprinting

A trillion dollar company just gave away the exact blueprints to one of its newest products. Tolerances, mating force, all of it, free. The why is the best part (full story on the blog, link in bio). What gadget would you print parts for first? #3DPrinting

[DC Additive Pros @DCAdditivePros]

A consumer electronics giant just agreed to pay up to $400 million for a 3D printing company, and it's not because they want to sell you a printer. The part they're really after fits in the palm of your hand, and the AI boom kind of falls apart without it. Full story on the blog, link in bio. So what would you guess the part is? #3DPrinting

[DC Additive Pros @DCAdditivePros]

Formlabs just dropped a machine that fits through a regular doorway, plugs into normal wall power, and claims triple the output of the big industrial nylon printers. The part nobody expected? The price tag. Full story on the blog, link in bio. So what would you print first with 61 liters of build volume? #3DPrinting #SLS

RAPID + TCT 2026, North America's biggest additive manufacturing show, made its Boston debut this spring.

The clearest signal from the floor wasn't a single machine, it was the shift from 'look what 3D printing can do' to 'here's how it runs in production.' We covered the themes that matter if you buy printed parts.

Shopping for a printer to run PEEK or ULTEM? Ignore the flashy specs.

What actually matters: a genuinely hot hotend (350-450C), an actively heated chamber, and a hardened nozzle. Speed and touchscreens won't fuse a high-temp part. Our buyer's guide breaks down the hardware that counts.

On the job site, the one bracket, knob, or adapter you need is always discontinued or sold in packs of 50.

A US shop can scan, design, and print a durable replacement in days, no minimums, in engineering plastics that survive real work (ASA, PETG, nylon CF, TPU). Not brittle PLA.

That cracked dash bezel or discontinued trim clip stalling a repair?

Scan it, reverse-engineer it, reprint it. 3D scanning to ~0.02 mm can recreate cosmetic and non-critical car parts the dealer back-orders for weeks. We covered what's reproducible and the safety line we won't cross.

Medical device teams that win move fast early: prototype, test in hand, revise, then tool.

On-demand 3D printing in PEEK, ULTEM 1010, and PPSU lets you iterate in days before committing to expensive injection molds. (We make prototypes and models, not FDA-cleared devices.)

Large-format 3D printing for $469?

Bambu Lab's new A2L brings a 330 x 320 x 325 mm build volume to an entry price, with up to 19 colors if you chain AMS units. Big for makers, with one honest catch for high-temp engineering parts. We broke down where it shines and where it stops.

Flame-retardant PPS just hit desktop FDM.

Polymaker's Fiberon PPS-GF20 is a UL94 V0, glass-filled engineering polymer that holds shape past 230C (after annealing) and shrugs off oils and solvents. Connector housings without injection tooling. We covered the specs and the process gotchas.

Active-foaming filaments expand as they print, trapping air so parts come out up to 50% lighter.

Temperature becomes a density dial: hotter = lighter and softer, cooler = denser and stiffer. Perfect for drones, RC, and grips. We compared LW-PLA and foaming PEBA, and when to switch to a real engineering polymer.
