pri cene 3d tlaciarne ta real gun vyjde aj lacnejsie :)

ale kokotiny treba pisat v adamovi

To nie je uplne pravda,
3D tlaciaren sa da postavit za par tisic korun, a hlavne potom uz na nej mozes tlacit kolko chces. (a co chces)

Ale s tou zbranou je to hype.

00000101000635330212938706955978069559970695609906956128

normalna pouzitelna 3D tlaciaren nestoji par tisic korun
ale ano, neznie to zle:)

rep-rap (na ktorom tlacil tu zbran) stoji par tisic,
teda suciastky do neho, poskladat si musis sam. (nas stal tak 8K pred rokom, a vyvoj ide dopredu)

Na nasom dosahujeme presnost pod milimeter,
tazko povedat kolko presne, ale som s tym napr. schopny tlacit funkcne kluce.

wake up;)

BTW neboli ste toto leto na nadvori SNG ukazovat ako ta tlaciaren tlaci?
(myslim, ze to bola vtedy nejaka akcia progressbaru ci co, ci ako)

000001010006353302129387069559780695599706956099069561280695630306956318

ty mas k nemu pristup na nejake self tlacenie?
:)
potreboval by som cosi

no ale co je normalna pouzitelna 3d tlaciaren?

aj reprapy vedia mat celkom kvalitny a pouzitelny vystup (to je ta za par tisic)

S prepacenim "nepodstatne otazky" typu "cena real zbrane vs. cena tlaciarne a cena materialu na vyrobu plastovej napodoby" ma v tomto pripade (vobec) nezaujimaju. (Toto nech si riesia kapitalisti a nech to nedava spavat im.)

To co je zaujimave a jemne znepokojive su napriklad veci ako "dostupnost home made zbrani" a aj samotny fakt toho, ze maju potencial byt z plastu a atd. a pod..

00000101000635330212938706955978069559970695605006962214

IMHO toto nie je vacsie ohrozenie ako clovek s prakom. Dostrel rovnaky, presnost takisto. Len tato 3d zbran IMHO nevydrzi viac ako 1 vystrel.

0000010100063533021293870695597806955997069560500696221406962597

Tri veci:
1. Tato zbran vydrazala viac ako jeden vystrel.

2. Povodna AR-15 ma dostrel cca 500 metrov, tato plastova nech by mala efektivny dostrel hoc 100 metrov, myslim, ze to bude viac nez dokazes "efektivne dostrelit" s prakom.

3. Mna znepokojuje smerovanie a buduce moznosti, nie dnesny stav technologie.

Ad. "vygidor": jj, dobre pises, presne pises.

Ad. "ntn": Niet sporu, ale tak hadam to co si pisal je snad (cca) vsetkym jasne. Snad. :-]

"The problem is that even the strongest 3D-printable thermoplastic currently available for the FDM process (Ultem 9085) doesn't even have half the tensile strength needed to withstand the 24,000 psi maximum allowed chamber pressure of the .22LR round as defined by SAAMI (the Sporting Arms and Manufacturer's Institute).
As such, yes, a 100 percent 3D-printed gun made on a RepRap could certainly go "bang," but even with a barrel of large enough diameter to keep it from exploding, there would be so much deformation in the bore that most of the available energy would be sapped by gas leakage around the projectile (to say nothing of the utter lack of accuracy). In the end, you'd have a smoking, charred crater left for a barrel bore after the single shot."

dostrel ar-15 komp. zbrane je cez 3km (3500+ metrov), to, co spominas je ucinny dostrel na bodovy ciel (point target).
sice neporovnatelne, ale vz.58 (ina raz ako ar-15 komp. zbran, ktoru "tlacili" na tej tlaciarni a ina dlzka hlavne, ktora je pre max. dostrel rozhodujuca) ma ucinny dostrel 600m na bodovy ciel a max. dostrel je cca 2800m a po celej dlzke je smrtiaci.

kazdopadne "amatersky zbrojar" nepotebuje ziadnu 3d tlaciaren, staci mu hornbach, baumax ci iny dodavatel a dielnicka s nastrojmi pre rucne a strojove opracovanie kovov ;)

Nie nie nie, vystrely mozu byt akekolvek, plastova hlaven proste neznesie ani ten tlak ani opotrebenie. Prvy vystrel ju zmeni na nepoznanie a bude IMHO prakticky nepouzitelna. Druha vec je ze pri vystrele sa projektil urcite neroztoci, co je potrebne pre dostrel aj presnost.

PS: buducnost je zla, s tym suhlasim

00000101000635330212938706955978069559970695605006956067

jasne, nech ta to nezaujima, lebo to sa vobec netyka toho, co ta jemne znepokojuje :)
niee
