以上是傳統的手槍結構

以下是該公司的聲明稿(Read Me File)

以下是Defense Distributed “解放者” 3D列印手槍教程的首次發佈。我們於2013年5月3日完

成該手槍的第一次性能測試,於2013年5月5日完成第二次性能測試。

我們的設計源於對EXP001和EXP002的研究和改良。對EXP002的改變主要包括:

-增加了槍管locking lug filet,以減少射擊時槍管承受的壓力。

-在握把上增加了0.2英寸的孔洞,從而組裝時不再需要螺絲。同時, 如果在距離拐角處

0.4*0.4英寸的位置上鑽0.2英寸的孔洞,AR-15的握把也將適用於本槍。另外,你也可以

選擇從Defense Distributed的官網上下載並列印AR-15的槍把,從而避免安裝時使用金屬螺

絲。

-抹除了流水號

-將hammer body撞針孔縮小至140mils以增加撞針的準確性。

-強化握把

如何合法組裝解放者手槍:

-僅僅列印出the frame sideways(最小尺寸是Z坐標軸???)

USC18 922(p)(2)(A)規定:“軍火”並不包括the frame or receiver及類似裝置。因此,不使

用鋼材,全塑膠列印出the frame部分是合法的。(I have no idea which parts they are)

-列印完the frame後,在扳機前方1.2*1.2*1.0英寸的孔洞處安裝一塊1.19*1.19*0.99英寸的

金屬。如果你不希望這塊金屬暴露出來,可以安裝底蓋遮住它。

-在固定後,這塊金屬禁止被移出,它是the frame的核心部分。現在,你的槍包含了6盎司

金屬,它就可以被各種安檢、掃描器器檢驗出來(完全合法了),接下來,你可以開始列印

剩下的部分了。

-列印剩下的所有部分

槍管必須沿Z軸放置。

the springs側面必須光滑。

在列印the hammer body時,要確保撞針孔位於Z軸上。

the hammer should be printed on its side

扳機must be printed on its side

.........................在Z軸上,以減小摩擦

...............................

................................(the way to place it... I cannot image what kind of way it is )

我們先組裝扳機。拿起扳機簧,你會發現在ovular hole的一側有個很小的凸槽,在這個凸

槽位置安裝扳機,同時給扳機簧留出足夠空間以防它碰觸the frame的底部。The spring’s

free end 應該指向槍的尾部,和扳機方向相反。將the spring的兩部分配對組裝,並插入the

frame。

接下來,我們來到the hammer部分。保持the striking cylinder面朝the frame前方,將the

hammer插入the hammer body, 安裝hammer閂固定。然後把兩個彈簧壓入the hammer,當

hammer豎起時,彈簧應被壓縮(而非伸展)。在兩個彈簧都被裝入後,拉出the hammer後

部的線圈孔,把the spring的連接棒塞入該線圈孔中。(....I can’t image the way they move

in the next two sentences),然後將另外一個spring 退回,並將the spring連接棒固定0於線圈

孔。把hammer拉回來並確認一切順利。把hammer拉回來後,放入螺絲釘並確保撞針外圈

套入該螺絲釘固定——這將在hammer豎起時保證螺絲釘不滑落。注意:確保撞針外圈帶凹

槽的一面面向the hammer。

之後,把the hammer放入the frame。確保the hammer和扳機固定緊密。插入三個frame螺

絲固定hammer。

最後,將握把滑入the frame並插入最後一個frame螺絲釘。

你的自由者手槍就組裝完成啦!

Tips: 在使用槍筒前,我們建議加熱丙酮至沸騰並擦拭槍管30秒以減少內經摩擦(treating

means wipe right?),這將增加槍管1到10發的壽命。

我們建議同時列印幾個備用槍管且每個槍管只使用一次。更換槍管十分方便:旋轉槍管以解

除鎖定,然後拉出槍管。如果槍管的固定凸輪損壞,請將手槍槍口指向地面並除去殘留部

位,再將一個新槍管放入,旋轉鎖定。

 

以下是原文:

This is the first DD Liberator release, tested functional on 5/3/2013 and again on 5/5/2013.  Design tweaks included from EXP001 and EXP002 experimental results.
Changes from EXP002:
-Barrel locking lug filet added to reduce stress concentration
-.2" hole added to handle to allow assembly without screw.  AR-15 grips will fit, but need a .2" hole drilled .4x.4" from corner.  Or download DD's modified AR-15 grip.  This is done so you don't need a metal screw to hold the grip on.
-SN removed.
-Hammer body firing pin hole reduced to 140mils to improve firing pin concentricity on primer.
-Trigger stiffened.

How to legally assemble the DD Liberator:
-Print (ONLY) the frame sideways (the shortest dimension is the Z axis).  USC18 922(p)(2)(A)*: "For the purposes of this subsection (The Undetectable Firearms Act of 1988) - the term 'firearm' does not include the frame or receiver of any such weapon;"
Thus, you can legally print ONLY the frame entirely in plastic, even without 3.7 ounces of steel. 

-Once the frame is finished, epoxy a 1.19x1.19x0.99" block of steel in the 1.2x1.2x1.0" hole in front of the trigger guard.  Add the bottom cover over the metal if you don't want it to show.

-Once the epoxy has tried, the steel is no longer removable, and is an integral part of the frame.  Now your gun has ~6 ounces of steel and is thus considered a 'detectable' firearm.  So now you can print all the other parts.

-Print all the other parts. 
The barrel must be built up in the z axis. 
The springs must be printed flat on their side. 
The hammer body should be printed such that the firing pin hole is in the z axis.
The hammer should be printed on its side.
The trigger must be printed on its side.
The spring connecting rod bushing should be printed up in the z axis, to reduce friction.
The spring connecting rod should be printed on its side.
All pins should be printed on their side to take advantage of intralayer strength.


We'll build the trigger first.  Take the trigger spring and note that there's a very small lip on one side of the ovular hole.  This lip mounts flush to the trigger piece, and gives the spring enough clearance to not drag on the bottom of the inside of the frame.  The spring's free ends should point away from the trigger, towards the back of the gun.  Mate these two pieces, and then insert into the frame.

Next, we'll build the hammer subassembly.  Insert the hammer into the hammer body with the striking cylinder facing the front of the frame.  Insert the hammer pin to connect the hammer to the hammer body.  Now press both coil springs onto the hammer body.  When the hammer is cocked, the coil spring diameter should reduce (not expand).  Once both coils are pressed on, pull one of the coil eyelets behind the hammer, and then insert the spring connecting rod into said eyelet.  Rest the rod on the hammer.  Slide the spring connecting rod bushing over the spring connecting rod, then pull the other spring back and insert the spring connecting rod into the eyelet.  Pull the hammer back and make sure everything is working well.  Pull the hammer back and drop in the nail and then insert the firing pin bushing concentric to the nail's head.  This keeps the nail from falling out when the hammer is cocked.  Notice that one side of the firing pin bushing is chamfered... that side faces the hammer.

Next, drop the hammer into the frame.  Note that the hammer secures the trigger.  Insert three frame pins to secure the hammer body.

Finally, slide the grip onto the frame and insert the grip pin.  Your Liberator is now ready to go!

Before firing a barrel, we recommend heating acetone to boiling and treating the barrel for ~30 seconds to decrease the inner diameter friction, which increases barrel life from 1 round to ~10 rounds.  Note that we recommend printing multiple barrels and using each only once.  Swapping the barrels is simple and fast: rotate the barrel to release the locking cam.  Pull up on the barrel.  If the barrel cam broke, turn the Liberator upside down to remove the debris.  Then drop your new barrel in and rotate it until it locks.
