⚠ READ FIRST — THE LCD SCREEN IS NOT INCLUDED IN ANY OPTION ON THIS PAGE
Not in the Upper Half. Not in the Mid Panel. Not in the Lower Half. Not in the Whole Unit. The LCD is a separate consumable part (replacement needed every ~1,000 printing hours) and is sold separately — link at the bottom of this page. On damaged/donor units the LCD is almost always already consumed (worn out) — never expect a working LCD from any unit or half on this page. No power cord / power brick, no vat tank, no build plate and no accessories are included with any option — parts only.
TOUCH SCREEN ≠ LCD SCREEN — two different parts, don't mix them up:
- Touch Screen = the small control display on the FRONT of the machine that you tap to run the printer. It is part of the Lower Half.
- LCD Screen = the large masking screen UNDER the resin tank that shapes the UV light for every printed layer. It mounts on the Mid Panel — and it is NEVER included in this listing.
THE 3 ZONES OF THE PRINTER (this is how every option below is cut):
| ⬆ UPPER HALF — everything ABOVE the red aluminum panel: Z tower, linear rails, Z axis assembly, build-plate arm. |
| 🟥 MID PANEL — the red aluminum panel itself, with the 2 threaded holes for the vat tank knobs. The LCD screen sits on this panel — and is NOT included. |
| ⬇ LOWER HALF — everything BELOW the red aluminum panel: UV light source, touch screen (front control display), mainboard, internal power board, fans. |
WHAT YOU GET — OPTION BY OPTION
| Option you pick | ✅ Included | ❌ NOT included |
|---|---|---|
| Upper Half | Z tower with linear rails, Z axis assembly, build-plate arm | No LCD, no mid panel, no lower half, no UV hood/lid (sold separately as UV Lids), no accessories |
| Mid Panel | The red aluminum panel with the 2 threaded holes for the vat tank knobs | LCD NOT included (it only mounts on this panel) — panel only, nothing else |
| Lower Half | Base unit with UV light source and Fresnel lens, touch screen (front control display), mainboard, internal power board, fans. TESTED before shipping: powers on, UV light source verified working | NO LCD SCREEN — the LCD is not part of the lower half. No power cord / power brick, no vat tank, no build plate |
| Z Axis Assembly | The Z axis portion of the upper half | Limit switch NOT included unless you ask for it in your order note |
| Fresnel Lens (under LCD) | The Fresnel lens only — the lens that sits between the UV light source and the LCD | It is NOT the LCD screen — lens only, no screen included | UV Lids (filthy) | The red UV cover hood only, cosmetic condition as described | Nothing else |
| Whole Unit (Defected) | One complete damaged donor unit | May miss one or ALL parts / hardware / accessories — see the warranty note below. LCD may be bad (it is a consumable) |
| Other Particular Parts | The single part you name in your order note (e.g. UV light source, touch screen, Fresnel lens) instead of a whole half | Anything you did not name |
CONDITION — PLEASE READ: every Lower Half is tested before shipping — we make sure it powers on and the UV light source is functional. All other options on this page are stripped from returned or damaged units as-is: the parts listed are physically PRESENT, but an individual part may itself carry the defect the donor unit was retired for. An inspection slip ships with your order noting what was found working / not working.
The same applies to LCDs everywhere in our store: even a used LCD that passes our light-exposure test carries no guarantee — the test only proves it lit up at the moment of inspection. LCDs are wear items; always plan on replacing them.
Need one specific part working? Leave a note WITH your order naming it (e.g. "I need the UV working") and we will pick a donor unit that matches. No note = we ship from the lot as-is.
*Parts for the Saturn 4 series are on a separate page (they are structurally different for stripping): https://greatdealsnv.com/products/s4-parts
Whole units w/ defects: the unit was returned in poor condition with heavy signs of wear/tear and aesthetic issues such as scratches, dents, cracking. It might not come with original factory packaging. It might miss one or ALL parts/hardware/accessories. Our store warranty: customers will make 1 FULLY functional unit for every purchase of 2 units — or you get FREE replacement parts on your fix-up projects. Great as a source of parts/hardware (if you buy just 1) or as DIY fix-up projects for experienced experts.
Most common defects/damage for resin 3D printers
— Upper half issues —
A) Bad monochrome masking LCD, not rendering the exact image shown on the touchscreen. This is routine maintenance (consumable part — replacement LCD is due/required every 1,000 hrs).
B) Movement issues — Z axis not moving/homing properly, buzzing, bent lead screw, etc.
— Lower half issues —
C) Bad UV — dim/partial/no UV light emission.
D) Miscellaneous issues: cosmetic body damage, stuck knobs, firmware errors, touch screen no response, not powering on (PSU), noisy fans, etc.
