	A single shot .380 ACP pistol.[2][4][5] Fully 3D printed including springs, requiring only a roofing nail Notable as the first publicly released printed firearm design
Grizzly,[3][8] Grizzly 2.0,[9] G22 v3[10]	2013-082013, August (original), G22 v3 (latest)[8][10]	Hybrid firearm: Rifle	Single-shot	FDM w/ ABS	"Matthew" (pseudonym)[8][9][10]	.22 caliber barrel liner, metal rods, metric fasteners, springs, screws	.22 LR

	It can hold 5 .22 caliber cartridges.[11][12] Unlike the many early 3D-printed firearm designs, which were overbuilt in order to withstand the pressures and strain on the material from modern gunpowder cartridges, the Reprringer is small and only slightly larger than an equivalent gun made from steel.[11]

Reason[22]	2013-112014, October	Weapon: M1911 pistol	Semi-automatic Recoil operation	DMLS[23]	Solid Concepts[24]		10mm Auto
	Created roughly after a year the first-known metal 3D-printed gun was produced.[22] Has the word "Reason" etched on it, along with an excerpt from the Declaration of Independence on the barrel.[23]
XPR-1[25]	2015-102015, October	Weapon: Plasma Armature Railgun		FDM	David Wirth[26]
	First 3D printed railgun structure. Closed source - designs and code released to research institutions only. Employed a mixture of traditional and additive manufacturing. Rails were traditionally machined, as well as the fasteners and electronics.
Uses a plastic frame, slide, and fire control components with a steel barrel liner, breechblock, firing pin, and spring. First in line of "PG22" single shot pistols and revolvers. Individually designed, rather than built off of open-source plans.
First commercial handheld coilgun.[27]
FGC-9 / FGC-9 MkII	2020, March 27 (MKI); 2021, April 16, (MKII)	Hybrid Firearm: Semiautomatic carbine or Short-Barreled Rifle or Pistol	Semi-automatic simple blowback	FDM	JStark1809 (DetDisp)	Steel round stock, springs, AR-15 fire control group springs, fasteners, stainless steel tubing	9×19mm Parabellum
	Based on Shuty AP-9. No parts kit required: barrel can be rifled via Electrochemical machining (ECM). Version two, labeled MKII, features an updated design with an H&K MP5 style charging handle. The MKII was released to work with a string of smaller releases, including an improved barrel making process and V2 Menendez Mag. Includes the "ButWhatAboutAmmo" tutorial for fabricating ammunition.
Thump 'n Grind[28]	2021, July	Signaling device: Launcher		FDM	AWCY?	Steel rods, tubing, AR-15 FCG, fasteners	37mm ammunition
The Harlot[29]	2022, February	Primarily printed firearm: Pistol	Single-shot	FDM	BAD-CAD / Black Lotus Coalition	.22 caliber barrel liner, spring, fasteners	.22 LR
	A mostly printed .22 LR pistol. Uses a DIY metal barrel, firing pin, and spring. Simple and extremely cheap, designed to cost $5-$8. Commonly created to be sold at gun buybacks for profit.[30] A large number of remixes and variants of this design have been created.
Urutau [31][32]	2024, August 20	Hybrid Firearm: Bullpup Short-Barreled Rifle or Standard Rifle[31]	Semi-Automatic Straight-Blowback[31]	FDM	Joseph The Parrot, A.K.A. Zé Carioca[31][32]	30cm or 1ft of 12mm X 20mm or 1/2” X 3/4” steel bar stock, Stainless Steel Rods, 16mm OD 8mm ID Steel Hydraulic Pipe, springs, screws, Long or Stainless Steel pins, M3 Threaded spacers with a diameter of 5mm, 623ZZ Ball Bearings, M3 Brass Heatset Inserts[31]	9x19mm
	While most of the underlying mechanics of The Urutau are comparable to the FGC-9 and Partisan 9, all parts were significantly redesigned.[31] All parts are made from easily accessible, less-firearm-related components that improve supply chain resilience and enhance the builder's operational security when sourcing materials.[31] Parts kits are commercially available to Americans but not required for anyone[33][34] Barrel is manufacturable with Electrochemical Machining (ECM)[35] It uses a telescoping bolt which is pinned together and glued in place, a 3D printed fire control group/trigger designed from the ground up and CZ Scorpion magazines[31] Aside from the ejection port, the entire gun is ambidextrous.[31] Urutau incorporates safety features to manage the risk of an out-of-battery detonation.[31] With all necessary machines, tools, and materials on hand and the time to treat the project like a full-time job, the Urutau is manufacturable in less than a week.[31] The estimated minimum cost to construct a Urutau stands at around $500 for the initial gun, including printer and hardware, and $200 for each subsequent gun.[31] Documentation written by RSmith28 includes a guide for avoiding detection by law enforcement[31][36][32] Files include "The New Second Amendment", a nine-page manifesto encouraging Urutau builders "to permanently undermine global firearm prohibition"[37][32] Given the open-source nature and CC0 1.0 Universal license applied to the Urutau, many modifications to the original design have appeared online.[38] Some of these modifications include modified grips and barrel covers.[38]

	An additively manufactured titanium weapon suppressor. It is 50% lighter than some conventional steel suppressors.[75] Oceania Defense has made three variations of the 5.56mm/.223 suppressor so far: the 556-45 Samson (an AR-15 suppressor designed to operate on semi auto Short-barreled rifle to 12.5" barrels), 556-SBR (designed for hard use on 10.5" barrel for AR-15 firearms in 5.56mm/.223 ammunition) and 556-45 Suppressor (direct thread on suppressor which overlaps the barrel designed to reduce a baffle strike)[73]

	An additively manufactured titanium weapon suppressor. 50% lighter than some conventional steel suppressors.[75] Oceania Defence made 3 variations of the 7.62mm rifle suppressor. the 300 BLK Long (designed for use with the 300 AAC Blackout cartridge in both subsonic and supersonic. It fits under the rail of a Samson or similar rail system on the AR-15-type rifle, but can to perform acceptably on bolt action 7.62×51mm/.308 rifles as well), 762-AR10 Suppressor (designed for the AR-10/LAR-8 7.62mm/.308 rifle but will also work with any bolt-action rifle in .30 caliber or less) and 762-G3 Suppressor (designed for the Heckler & Koch G3 and fits the HK91 series of 7.62mm/.308 rifles, as well as the HK33 and HK93 series of 5.56×45mm rifles).[78]
Small-caliber suppressors: Long version for 9mm carbines[79] UTU for pistols, including M1911 and 9mm[80]	2013-11November 2013[74]	Muzzle device: Titanium pistol suppressor[79]	SLM w/ Titanium[75]	Oceania Defence Ltd.[75][74][76] and Rapid Advanced Manufacturing[77]	9x19mm Parabellum, .45 ACP
	Long version is designed to operate on 9×19mm Parabellum carbines firing fully automatic.[79] It fits under the rail of a Samson or similar rail system on the AR-15-type rifle.[79] This is a sealed can and is only suitable for use with jacketed bullets.[79] Pistol version is designed with a Neilsen which allows it to be used with most of the common John Browning tilting-barrel designs, including the swinging-linked M1911 and the cam-lock system operated Glock pistols. The Neilsen is an assembly in the aft end of the suppressor that allows the gasses to push the suppressor forward while allowing the unimpeded rearward movement of the barrel and slide assembly using a stainless steel spring and titanium piston.[80] It is able to function well with a wide range of ammo, although its sound reduction performs best with subsonic bullets heavier than 124 grains, with 147 or 158 grain bullets being the quietest.[80] It is designed to be run wet or dry, averaging 127.7–128.4 dBA with 147 grain or 127.6–134.2 dBA with 124 grain when dry and 123.1 dBA with 147 grain or 129.1 dBA with 124 grain when wet.[80] It is an additively manufactured titanium weapon suppressor. It is 50% lighter than some conventional steel suppressors[75]

ABS

Acrylonitrile butadiene styrene, a common thermoplastic with relatively high heat resistance.

ABSplus is a stronger, proprietary blend of ABS by Stratasys.

PLA

Polylactic acid, a bio-plastic. Easier to print, stiffer, and more brittle than other plastics.
