1. Silicone Material Introduction

Full-size figures use one of two skins: platinum-cure silicone or thermoplastic elastomer, usually shortened to TPE. Underneath sits a steel or PVC skeleton wrapped in foam, or a hollow cavity in cheaper builds. The skin decides feel and lifespan; the core decides weight.

What the Outer Layer Is Made Of

Silicone cures from two parts without shrinking, so it holds mold detail down to a few tenths of a millimeter. Softer blends feel more lifelike but tear at seams. TPE is poured, stays stretchier, and loses mineral oil over time, which is why older bodies look dry.

Silicone vs TPE: A Practical Comparison

Ranges below reflect mid-range and premium builds.

Where Electronics Meet the Body

A connected head holds the speaker, microphone and control board; the chest or abdomen holds the battery and harness. Cables pass through the neck and shoulder, which flex most, so connected figures develop faults earlier.

Check where the charging port sits: ports under a removable scalp panel stay drier than exposed neck ones. A well-built silicone sex doll shows its port and seam construction in the product photos, which is a fair test of the shell design.

Hybrid Builds and Foam Cores

A silicone head on a TPE body is the standard mid-range build now. Foam cores cut weight by 20 to 30 percent, which matters above 160 cm and matters twice as much on stairs.

2. Customization Options

Customization is narrower than catalogs imply. You choose from existing molds, and the decisions that matter are fit, finish and serviceability.

Faces, Hair, and Eyes

Most makers offer fixed head sculpts. You pick a head, skin tone, eye color and wig; makeup is painted and sealed at the factory. Interchangeable heads let one body carry two looks.

Body, Skin Tone, and Proportions

Expect one or two heights per mold family, two to six skin tones, and options such as breast size, hip width and standing feet. Standing feet protect the soles if the figure is posed upright. Bespoke proportions add weeks and often double the price.

Electronic Options and What They Add

Electronics are sold as tiers:

• Voice only. A speaker with recorded or app-generated speech, plus a microphone for wake words; adds 150 to 400 US dollars.
• App control. Bluetooth or Wi-Fi pairing for settings, voice packs and firmware; adds 200 to 500 dollars.
• Touch sensors. Pads in the chest, hips or hands trigger speech or vibration; adds 300 to 700 dollars.
• Animatronics. Motors for blinking, jaw, head turn or hip motion; adds 800 to 2,500 dollars and the most failure points.

What Cannot Be Changed Later

Skeleton type, joint count, battery placement and port position are fixed at build time. Changing them means returning the body. A compact mini sex doll at 100 cm often has no electronics bay at all.

3. Buying Guide

Weight is the specification buyers underestimate, and it decides whether a figure gets used or stored. Choose materials inside the limit set by your space and your stairs.

Start With Height, Weight, and Storage

A 160 cm TPE body at 32 kg is manageable on a bed and awkward on stairs. A silicone body of the same height at 45 kg is a two-person lift. A 165 cm figure needs a case at least 170 cm long, and a fitted case adds 30 to 120 dollars.

Price Bands and What They Buy

Below 900 dollars you get TPE under 150 cm, a torso, or a compact model with a basic skeleton. Between 1,200 and 2,500 dollars, expect a full-size TPE body with a 12-joint skeleton or a smaller silicone figure. Above 3,000 dollars, silicone shells, foam cores and electronics become realistic.

Electronics take a large share of the premium and a small share of the usable life, so budget for the body first. A sex doll torso at 8 to 15 kg is the cheapest way to test the material.

Skeleton, Joints, and Poseability

Listings usually quote 10 to 16 joints: neck, shoulders, elbows, wrists, waist, hips, knees and ankles, with articulated fingers adding up to 10 points per hand. More joints mean more poses and more places to loosen.

A Pre-Purchase Checklist

• Weight in kilograms, confirmed in writing.
• Joint count and skeleton material.
• Battery runtime and charge time.
• Warranty split by body and electronics.
• Spare heads and chargers in stock.
• Return window and freight responsibility.

4. Maintenance & Care

The body needs the same routine with or without electronics. The electronics add two rules: keep water out of the head, keep the battery away from heat.

Cleaning Without Damaging Electronics

Power down and unplug first. Use mild, fragrance-free soap on a soft cloth, wipe seams and folds, dry with microfiber, and let the surface air for 30 minutes before dressing. Keep water off the neck seam and port covers. Silicone tolerates this indefinitely; TPE needs renewing powder every two to four weeks.

Charging, Storage, and Battery Care

Built-in packs are often 5,000 to 10,000 mAh and give four to ten hours of mixed use. Charge on a hard surface and avoid leaving a full pack plugged in for days. For storage over a month, charge to half and top up every three months. Store flat or on a stand to avoid deforming a hip joint.

Repair and Spare Parts

Silicone patches with a platinum-cure kit; TPE needs a patch or a new skin section. Speakers and sensor pads are often replaceable when the maker stocks them, so ask whether the head can be serviced separately. A failed board should not scrap a 3,000 dollar body.

5. Shipping & Privacy Policy

Two privacy questions apply to a connected figure: who sees the box, and who sees the data.

Packaging and Delivery

Orders ship in a plain, double-walled carton with no product name on the label and a neutral sender. Dispatch is usually 7 to 20 business days depending on build and destination, and large crates often need a signature. Photograph crush damage before signing; carriers usually require a claim within 48 to 72 hours.

Data Privacy on Connected Models

A connected figure can collect voice clips, app usage, sensor triggers and location. Check whether speech is processed on the device or in the cloud, whether an account is mandatory, and whether recordings are stored. Use a dedicated email address, deny location permissions, and turn off cloud voice history. Treat any Wi-Fi model as a microphone in your home.

Import Rules Are Yours to Check

Customs rules vary and change without notice. Some countries treat full-size figures as obscene material; others apply duty by weight or declared material. No retailer can guarantee an outcome at the border, and we do not. Confirm the rules for your address before ordering and keep the invoice to hand.

6. Trust & Guarantee

The body and the electronics fail differently, so they should carry different terms.

What a Warranty Usually Covers

Typical terms are 30 days on seam and mold defects, 6 to 12 months on electronics and 12 months on the skeleton. Reputable sellers replace a faulty board when moisture or impact did not cause the fault. Get the split in writing; a one-year headline often hides a 30-day body clause.

What It Usually Excludes

Water damage, drops, melted TPE from heat, dye stains and joint loosening are almost always excluded, as are battery degradation and wear on painted details. That mirrors a phone warranty, so test every feature in the first month.

How to Vet a Seller

Look for a physical address, a working phone number and a returns policy that names who pays freight. Ask for a photo of the actual unit rather than a catalog render. A published best sex dolls comparison helps here, because it shows how specifications are normally presented.

Final Thoughts

An AI sex doll makes sense when you want a premium body and treat the electronics as a detachable extra. It makes less sense when software is the main reason for buying, because the body outlives the board and the app may not outlive the warranty. Set the budget around the body, confirm the warranty split, and judge the shell before the software. For construction detail, start with the realistic sex dolls range.
