This two-part model kit represents the Maybach HL230 P30 engine used during World War Two by many German heavy tanks including late Tiger Is, King TIgers (Tiger IIs), Panthers, Jagpanthers, Jagdtigers, and late Stuermtigers. This model is intended as an accurate replacement for the Tamiya 1/25 scale TIger I's wholly inaccurate, largely fictional, engine model. Some adjustment to the Tamiya kit's parts may be necessary for best fit. 3D-printed acrylic plastic is brittle. Care is recommended during assembly and handling.
This 3D-printed motor is designed from scans of original factory drawings, entitled "French Army studies of captured equipment, 1945: General Arrangement Drawings HL230 P30", in the possession of the bureau d'études de l'Atelier d'Issy-les-MoulineauX (AMX).
Some part cleanup will be necessary. During the 3D printing process, a waxy substance is used to support certain part features. Although the parts are cleaned by Shapeways afterwards, some waxy residue may remain. It can be safely removed with water and a mild aqueous detergent like "Dawn" dishwashing detergent, baby shampoo (no conditioner), or "Simple Green" using an old, soft toothbrush, Q-tips or pipe cleaners. Customers report that "Bestine" and "Goo Gone" also work well.
During the printing process, liquid resin is cured by ultraviolet light. Microscopic bits of resin may remain uncured. Let your parts sit in direct sunlight for a few hours to fully cure the resin. After your parts have fully cured, careful use of an inexpensive "air eraser" emitting common household baking soda can help smooth surfaces or remove unwanted frost without harming detail prior to painting. An air eraser, similar to an airbrush but much cheaper, can be found on Amazon.com. Models by Harbor Freight and Paasche are popular.
Water-based acrylic paints meant for plastics is strongly recommended. Other paints, especially enamels, may not cure on Frosted Detail 3D-printed plastics.

From Wikipedia: "The Maybach HL230 was a water-cooled 60° 23 liter V12 gasoline engine designed by Maybach. It was used during World War II in heavy German tanks, namely the Panther, Jagdpanther, Tiger II, Jagdtiger (HL230 P30), and later versions of the Tiger Iand Sturmtiger (HL230 P45)....The engine was a follow-up version of the slightly smaller HL210 that had a displacement of 21 liters and, unlike the HL230, analuminium crankcase and block. The HL210 was used to equip the first 250 Tiger I tanks built.
"The engine had a volume of 23,095 cm³ (approx. 1,925 cm³ per cylinder) and a maximum output of 700 PS (690 hp, 515 kW) at 3,000 rpm. Maximum torque is 1850 Nm at 2,100 rpm. Typical output was 600 PS (592 hp, 441 kW) at 2,500 rpm.
"The crankcase and block were made of cast grey iron. The cylinder heads were made from cast-iron. The engine weighs 1200 kg and its dimensions were 1000 x 1190 x 1310 mm. Aspiration was provided by four twin-choke Solex type 52JFF carburettors. As was typical practice for Maybach, the engine used a tunnel crankshaft.
Approximately 9,000 HL230s were produced in total by Maybach, Auto Union and Daimler-Benz."
